Updated September 25, 2026. A guide for California families to who runs jails and prisons, who goes where, daily life, the history behind the two systems, and the decisions that matter after an arrest. Legal and operational details were checked against court, corrections, county, and government research sources. Statistics below identify their reporting periods.
Quick answer: A jail usually holds people after arrest, while a case is pending, or during a local sentence. A prison generally holds people serving a state or federal sentence after conviction. California has an important exception to the usual short-stay description of jail: some felony sentences last years and are served in county jail. For a family seeking release, the decisive question is the person’s legal status, charges, and holds. Being in jail does not automatically mean bail is available, and an ordinary bail bond does not cancel a prison sentence.
Jail vs. Prison at a Glance
| Question | County or local jail | State or federal prison |
|---|---|---|
| Who runs it? | Usually a sheriff or another local corrections agency | A state corrections department or the federal Bureau of Prisons |
| Who is held there? | People awaiting court action, people serving local sentences, and people held for other authorities | Primarily people serving sentences after conviction; some correctional systems also operate pretrial facilities |
| Does being there mean someone was convicted? | No. Many people in jail have not been convicted on the current charge | Usually, when referring to someone serving a prison sentence |
| How long is the stay? | It can be hours, days, months, or years, depending on the case and sentence | Generally longer sentences, with the release date governed by the sentence and applicable law |
| Can bail help? | Sometimes, when the charges and custody status allow release on bail | An ordinary bail bond does not end a prison sentence; postconviction release requires a separate legal basis |
| What happens day to day? | Booking, screening, court appearances, releases, housing, and local programs | Classification, housing, work and education assignments, treatment, visits, and release preparation |
| What should a family check first? | Booking record, all holds, court date, bail status, and the correct facility | Corrections locator, institution assignment, visiting rules, and the person’s lawyer |
| California agencies | County agencies, with state minimum standards and inspections by the Board of State and Community Corrections | California Department of Corrections and Rehabilitation, usually called CDCR; federal custody is separate |

What Is a Jail?
A jail is the local custody system most families encounter after an arrest. It holds people while the courts determine what happens next, as well as people serving local sentences. The familiar description, "jail is for a year or less," is a useful starting point for the national distinction. It is an incomplete description of California law.
Under Penal Code section 1170(h), specified felony sentences can be served in county jail. Whether that provision applies depends on the offense and statutory exclusions, including relevant prior convictions and registration requirements. A felony label alone does not tell a family where the sentence will be served.
Sheriffs operate most California county jails. Government Code section 26605 establishes the sheriff’s usual responsibility, but there are exceptions. Napa County’s Department of Corrections, for example, operates separately from its sheriff. The Board of State and Community Corrections, or BSCC, sets minimum standards and inspects local detention facilities. It does not manage each jail’s daily operations.
The national numbers show why jail is so closely connected to unfinished cases. In the Bureau of Justice Statistics’ final 2024 report, published September 2026, local jails held 658,700 people at midyear, and 68 percent were classified as unconvicted. During July 2023 through June 2024, they recorded 7.9 million admissions and an estimated average stay of 31 days. Admissions count booking events, including repeat admissions, rather than unique people.
Those are national figures, not a prediction for an individual case. Someone released after booking and someone waiting many months for trial both belong to the same system. An average cannot tell a family when their person will come home.
What Is a Prison?
A prison generally holds people serving longer sentences after conviction. In California state cases, CDCR operates the prison system. Federal criminal cases use a separate system, including Bureau of Prisons institutions and detention centers.
The agency’s name is not enough to establish someone’s legal status. A federal detention center can hold a person awaiting trial. Some states combine jail and prison functions within one corrections department. Immigration detention is a separate civil process and should not be treated as an ordinary California criminal-bail case. Start with the arresting authority and actual custody record.
For California’s current scale, the CDCR population report for September 23, 2026 counted 85,646 people in its institutions and 87,604 when conservation camps were included. Its broader in-custody and community reentry supervision total was 88,893. These categories are different, so they should not be mixed with one another’s capacity percentages.
The same report placed institutions at 126.4 percent of design capacity. Its footnote explains a September change that excludes housing units inactive for more than a year from that calculation. A comparison with an older percentage must account for that change. The report still listed California Rehabilitation Center, but with zero residents, during the announced closure process.
For families, the practical difference is the length and structure of custody. CDCR’s reception process includes evaluation, classification, and placement. The department describes an initial reception and classification period of up to 90 days, but approval, bed availability, and transport can add time before a move to the assigned institution. A transfer can change visiting eligibility and communication procedures, so check the institution’s rules rather than applying the former jail’s rules.
How Jails and Prisons Operate Day to Day
Jail: a system built around arrivals, court, and releases
Booking creates a series of responsibilities: identify the person, document the charges and property, screen for health needs, decide appropriate housing, and connect custody to the court calendar. A person may leave quickly, move to another agency, or remain for a lengthy case. Jail administrators must plan for those different possibilities at the same time.
That turnover makes continuity difficult. Someone can arrive without medication records, miss a program because of a court trip, or transfer before a treatment plan is established. These are reasons to ask specific questions about a facility’s services. They do not establish that every jail lacks treatment or that every person arriving at prison is medically stable.
Staffing also varies. Some counties use sheriff’s deputies, others use correctional deputies or corrections officers, and some combine different roles. The California Commission on Peace Officer Standards and Training describes the distinct jail-deputy training framework. Los Angeles also offers a custody career track. Describing jail work as merely a temporary stop before patrol misses that professional specialization.
California’s local detention rules establish minimum requirements for visiting and other conditions. The applicable rules depend on the type of facility and can contain exceptions. Families should read the jail’s current visiting instructions, including approval, identification, scheduling, and whether a visit is in person or by video.
Prison: longer assignments and more structured routines
Prisons organize daily life around housing assignments, security counts, programs, work, meals, movement, and visits. A longer stay can make a sustained educational or vocational course possible. It can also mean a longer separation from children, work, and the community. Access to a program still depends on eligibility, assignment, staffing, and the institution.
CDCR offers contact, noncontact, and eligible family visits. These are different arrangements with their own rules. Family visiting is not available to everyone. Audio calls from CDCR institutions became free in January 2023, but access remains subject to institutional procedures.
Medical care also has a different administrative structure. California Correctional Health Care Services operates within a system shaped by a receivership ordered in 2005, with the first Receiver appointed in 2006. County jail care is organized locally. A family dealing with a transfer should give the receiving facility current medication and health information through its designated process and raise urgent concerns promptly.
The main difference is organizational. Jails manage large numbers of uncertain stays and court-related movements. Prisons plan for longer periods of custody. Neither structure guarantees safety, adequate treatment, or a smooth transition.
In Their Words: Is Jail Worse Than Prison?
Some people who have lived in both describe jail as harder to endure day to day. Their accounts help explain experiences that a population table cannot capture. They are testimony about particular places and periods, not a representative survey of every jail and prison.
Christopher Blackwell, writing in May 2024 about a two-week return to Pierce County Jail in December 2022 after years in Washington prisons, described people experiencing "the worst days of their lives." His firsthand account in The Appeal focuses on instability and the difficulty of returning to that environment.
In The Marshall Project’s 2015 Rikers oral history, Robert Eaddy said, "Once you get upstate, you can relax." That comparison described his experience of New York’s jail and prison systems. It does not promise that prison will feel safer for someone else.
In a March 2024 Vera Institute account, James Nelson, an organizer with Dignity and Power Now, recalled months in Men’s Central Jail in 1986 before years in state custody. His account describes violence and the lasting effects of that experience. It is valuable testimony about the jail he knew, with a specific historical setting.
There is a serious counterweight. Prison can impose years or decades of separation, and individual prisons have documented violence and care failures. Historical BJS suicide data for 2000-2019 show different patterns across jail and prison systems, but a national rate cannot identify the safer housing assignment for a particular person today.
Our separate guides examine documented conditions in California county jails and California state prisons. For a family making decisions now, the actual facility, housing, health needs, and available legal options matter more than a blanket declaration that jail or prison is always worse.
Why Do Jails and Prisons Both Exist?
The division developed over time. Local detention for people awaiting legal proceedings long predates the modern penitentiary. The Assize of Clarendon of 1166, for example, directed the creation of county jails where none existed. Colonial America inherited local detention institutions along with other English legal structures.
American reformers later expanded imprisonment itself as a sentence. Philadelphia’s Walnut Street Jail became an important early penitentiary experiment in 1790, and Eastern State Penitentiary opened in 1829. Those developments helped shape the modern prison. They do not mean Americans invented confinement or every form of prison.
The two functions developed different administrative homes: local governments continued to hold people near local courts, while states built institutions for longer sentences. American federalism reinforced the separation. Federal criminal cases added another correctional system.
That history explains the familiar arrangement, but it does not make it inevitable. Some states place both functions in a statewide corrections system. Other countries organize pretrial and sentenced custody differently while still making a legal distinction between an accusation and a conviction.
How Other Countries Organize Custody
"Remand" is a useful word when reading about custody outside the United States. It commonly refers to holding someone while proceedings are pending. The country may call the building a prison even though the person has not been convicted.
The Norwegian Correctional Service manages both pretrial detention and sentenced custody. Its emphasis on normality and preparation for release has influenced reforms elsewhere. It does not follow that Norway has no pretrial detention, or that every country has one national corrections agency.
Canada uses a different division. Its official corrections statistics distinguish federal custody for sentences of two years or more from provincial and territorial custody for shorter sentences and remand. That is a different boundary from the usual American county-jail versus state-prison arrangement.
California has adopted ideas from international corrections through the California Model. Similar ideas have also been tried in local American custody. A National Institute of Justice review includes the Middlesex House of Correction and Jail’s P.A.C.T. program, opened in 2018. The review describes emerging initiatives and the need for evaluation, not proof that a particular design works equally well everywhere.
Comparisons are most useful when they identify a practice that can be evaluated, such as staff training, daily activity, or continuity of care. An international reoffending percentage is much less useful without knowing the release cohort, follow-up period, definition of reoffending, and people counted.
How California Built Two Custody Systems
California’s early prison history began with confinement aboard the Waban and construction at San Quentin. CDCR’s history of the prison ships describes how those origins led to the state’s first prison. San Quentin opened in 1852, and Folsom followed in 1880. County jails developed alongside local courts and law enforcement.
The modern turning point was the overcrowding litigation. In Brown v. Plata, decided in 2011, the U.S. Supreme Court upheld an order requiring California to reduce its prison population to 137.5 percent of design capacity. The case concerned the relationship between overcrowding and constitutionally inadequate medical and mental health care.
California’s 2011 public safety realignment then shifted responsibility for specified felony sentences and some postrelease supervision to counties. It did not simply empty prisons into local jails. The law changed where eligible sentences would be served and which agency would supervise eligible people after release. The Judicial Council’s realignment overview explains those distinct changes.
For jails, that meant responsibilities beyond a quick stay near court. Some facilities now had to accommodate people serving substantial felony terms as well as people newly arrested. The Legislative Analyst’s Office’s realignment retrospective discusses the fiscal and operational consequences, including state support for local detention construction.
More recently, falling prison populations have led to closures and consolidation. Those decisions change local employment, travel for families, and the distribution of people among remaining facilities. A lower statewide count does not by itself establish better conditions inside every institution.
How California Connects Jails, Courts, and Prisons
Arrest and the first court appearance
After an arrest, a person may be cited and released, released under an available pretrial process, or held for court. California courts explain what happens at arraignment, including the charges, counsel, plea, and release issues.
Penal Code section 825 requires an appearance without unnecessary delay and generally within 48 hours, with statutory exclusions and court-session provisions. The rule is not a promise that every arrest leads to court exactly two calendar days later. Our guide to how long it takes to see a judge explains the practical timing question in more detail.
People who are released can continue through the case outside custody. Arraignment, trial, and sentencing do not inherently require someone to remain in jail throughout.
Sentencing and transfer
A case can end in dismissal, acquittal, diversion, probation, a local sentence, a prison sentence, or another lawful outcome. When section 1170(h) applies, the sentence may include county jail and a period of mandatory supervision. California Rule of Court 4.415 addresses the decision to suspend a concluding portion of an eligible sentence for that supervision.
When a state prison commitment is imposed, Penal Code section 1216 governs delivery to the prison system. Transport and reception involve agency coordination. The five-working-day provision sometimes mentioned in this context concerns county reimbursement under Penal Code section 4016.5. It is not a guaranteed transfer deadline a family can use to predict a person’s location.
Release from prison and supervision
Some people leaving prison go to county postrelease community supervision, called PRCS. Others remain under state parole. The applicable route depends on the law and the person’s case. Violations can result in local custody, but not every violation produces a jail term, and special rules can require a return to CDCR for certain people on life parole. The Judicial Council overview explains the distinction.
The practical lesson is to ask which agency has authority at each stage. The booking jail, sentencing court, receiving prison, and supervising department can be different agencies with different records and responsibilities.
How the Major Counties Run Their Jails
These examples show the shape of local systems. They are not a list of current vacancies or a prediction of where a particular arrest will be booked. For an individual, use the county’s current locator and confirm any transfer.
| County | How its jail system is organized | Official starting point |
|---|---|---|
| Los Angeles | A large network including downtown facilities and the Pitchess complex in Castaic. The sheriff reported an average daily population of 13,054 in 2025. | 2025 custody report |
| San Diego | Seven detention facilities, with different intake and housing roles. | Detention Services Bureau |
| San Bernardino | Four main adult detention facilities, including West Valley. | Sheriff’s corrections division |
| Orange | Multiple custody facilities, including Theo Lacy. Its listed 3,442-bed capacity is a capacity figure, not a current headcount. | Theo Lacy facility information |
| Riverside | Five jails spread across a geographically large county. | Corrections Operations |
| Sacramento | Main Jail and Rio Cosumnes Correctional Center have distinct roles within one county system. | County jail fact sheet |
| Alameda | Santa Rita is the county’s principal adult jail. Long custody spells make the short-stay stereotype especially incomplete. | County jail population analysis |
| San Francisco | The system includes County Jail No. 2 and County Jail No. 3, with separate visiting schedules. Confirm the housing facility before arranging a visit. | Official jail visiting information |
Alameda’s analysis illustrates a measurement issue worth understanding. The average time already spent in custody by people present on two snapshot dates rose from 218 days on June 29, 2019, to 303 days on December 28, 2024. That is not the average completed stay of everyone booked during either year. A snapshot naturally gives more weight to people who remain for a long time.
County averages can conceal substantial differences among housing units and populations. A jail may simultaneously release many people quickly and hold a smaller group for years. A facility guide should therefore identify the relevant dates, population, and measure instead of treating one number as the experience of every person inside.
The Benefits and Costs of Running Both
Local custody can keep a person closer to the court handling the case and, sometimes, closer to family. A local agency can coordinate with county treatment programs and reentry services. Those benefits depend on geography and actual placement. California’s large counties and interstate or federal cases can still leave families traveling long distances.
State prisons can pool resources for specialized treatment, education, and long-term housing. CDCR’s conservation camp program is one example of an organized statewide program, operated with fire agencies for eligible participants. Its existence does not establish that every prison offers equivalent opportunities.
Separate systems also create handoffs. Records, medications, property, family contact, and release planning must move with the person. Different agencies do not make continuity impossible, but they make deliberate coordination necessary. A family should know whom to contact at both the sending and receiving facility.
Costs should be compared with the same care as population figures. The Legislative Analyst’s Office estimates $127,800 per state prisoner for 2025-26, including security, health care, and other expenses. A Contra Costa County grand jury report issued in May 2026 reported local detention spending of approximately $396 per person per day for 2025. Those figures concern different systems and accounting periods. They show that local custody can be expensive; they do not establish that every jail costs more than every prison.
Nor does dividing total spending by the population tell us how much money one release would save. Staffing, buildings, and other costs may persist until a unit or facility closes. The LAO’s analysis of prison capacity examines why institution-level decisions matter for savings.
Counties Without Full-Service Jails and States With Combined Systems
Alpine County offers a useful exception to the assumption that every California county operates a jail. The Alpine County Sheriff’s Office says it has no jail facilities and contracts for jail services with El Dorado and Calaveras counties. That does not mean an Alpine arrest avoids custody, or that every person is sent to the same receiving jail.
Sierra County operates a temporary holding facility. It reports housing people primarily in Nevada County and occasionally in Plumas County. For families, the important distinction is between the agency handling the case and the facility physically holding the person.
At the state level, combined systems put jail and prison functions under a statewide corrections agency. The September 2026 BJS jail report identifies combined systems in Alaska, Connecticut, Delaware, Hawaii, Rhode Island, Vermont, and West Virginia. It separately includes 14 independently operated Alaska jails. "Combined system" therefore does not mean that no local lockup or jail can exist.
Connecticut’s correctional history describes the creation of the Department of Correction in 1968 by combining the State Jail Administration, separate institutions, and parole-related functions. Rhode Island’s adult correctional institutions are located on a campus in Cranston, including the men’s intake facility. Those arrangements show that government can organize the same custody functions differently.
One agency can simplify responsibility for a transfer, but consolidation does not guarantee uninterrupted care, consistent staffing, or lower mortality. State size, facilities, budgets, and the population served all matter. These examples are possible administrative models, not proof that copying them would produce the same outcomes in California.
Does Minnesota Run Jails and Prisons Better Than California?
Minnesota is a useful comparison because it also has local jails and a state prison system. Some historical measures favor Minnesota. Others do not. The available figures support a comparison of particular outcomes, not a declaration that one state is better on every measure.
| Historical measure | California | Minnesota | National figure in the same source |
|---|---|---|---|
| State prison deaths per 100,000 in 2019 | 330 | 113 | 330 |
| Average annual state prison suicide rate per 100,000, 2001-2019 | 21 | 16 | 18 |
| Average annual local jail suicide rate per 100,000, 2000-2019 | 40 | 60 | 43 |
Sources: BJS prison mortality tables and BJS suicide tables. These are historical, unadjusted rates, not current facility ratings. The jail-suicide row is a counterweight to the lower Minnesota prison figures.
Minnesota’s corrections department licenses and inspects local correctional facilities, and its Ombuds for Corrections accepts complaints about local facilities. Those are concrete oversight arrangements to examine. Their existence alone does not prove that they caused a difference in death rates.
Recidivism comparisons require another distinction. California’s report on people released in fiscal year 2020-21 reports a three-year conviction rate of 39.5 percent for the overall cohort. Minnesota’s January 2026 performance report reports, for its 2021 release cohort, a 21 percent return-to-prison rate for a new felony and a 33 percent new-felony reconviction rate. Those are different outcomes, and the California measure is not limited to the same new-felony definition.
The responsible question is what a specific policy changes for a comparable group over a comparable period. Differences in age, illness, sentence length, local conditions, and how a state counts an event can change the results. A historical table can guide questions without settling which system is best today.
What Families Should Do
- Identify the correct custody authority. Start with the arresting agency and the person’s full name and date of birth. A recent arrest can lead to a city or county facility, federal custody, or another agency. Our California inmate locator guide and guide to finding someone in jail explain the search process.
- Confirm the reason for every hold. Ask about the current charges, warrants, other cases, supervision holds, and any no-bail order. A bond on one charge does not necessarily resolve a separate reason for custody.
- Get the court date and lawyer’s information. Ask defense counsel about release options, a bail review, and any order that needs attention. Release can involve a citation, recognizance, conditions, or bail, depending on the case. Our California bail-amount guide explains the role of schedules and court decisions.
- Keep transfer and health information together. Record booking and case numbers, the current facility, and the receiving institution after a transfer. Use the facility’s designated process for important health information. A communication gap should be checked, especially when there is a specific safety or medical concern.
- Check contact rules before traveling or sending money. Confirm visiting approval, identification, appointments, telephone procedures, and authorized payment services on the facility’s own website. Rules can change after a transfer.
- Make a plan for release. Arrange transportation, a reliable way to receive notices, and reminders for court and supervision appointments. Read every condition of release and ask the lawyer to explain anything unclear.
How to Stay Out of Both
There is no universal promise that a person can avoid custody. What a family can do is reduce preventable problems and get the right legal help early.
Attend required court appearances, keep contact information current, and follow the actual release order. If a date has been missed, contact defense counsel promptly instead of assuming the problem will resolve itself. Our guide to what happens when a bond is revoked explains why a missed appearance or other violation needs attention.
Ask counsel whether diversion, treatment, probation, or another alternative is available in the particular case. Eligibility depends on the charges, history, statutory rules, and the court’s decision. A program that helped one person may not be available to another.
Keep financial obligations and court conditions distinct. An unpaid contractual balance is not itself a new criminal conviction. Problems with a bond or a proposed surrender have their own rules and should be addressed directly with counsel and the bail company. Do not ignore notices or treat a payment dispute as permission to miss court.
How Bail Hotline Can Help
Everything above this section is written to be useful whether or not you ever call us. This is the one place we talk about ourselves.
Bail Hotline is family-owned and has served families since 2004. We are licensed through our parent company, DMCG, Inc., with the California Department of Insurance, license #1845394. Our agents answer 24 hours a day, 7 days a week, at (888) 958-1228.
Someone was just arrested. We help you take the next step.
Families do not need to understand the whole corrections system before asking for help. Bring us the information you have. We can help clarify the booking and bond process, explain what is needed for an eligible bond, and walk the cosigner through the agreement before signing.
- A person to call around the clock. Our dedicated posting agents work 24/7, so an arrest outside ordinary business hours does not leave you waiting for our office to open.
- Clear explanations before you commit. We walk every cosigner through the agreement and explain the obligations involved.
- Support while the case is open. We provide text court-date reminders and help clients understand the steps involved in a warrant walk-through.
- Attention to complicated cases. A large, complicated, or out-of-county bond is not an automatic no. We review the situation and explain what we can do.
Every case is different. The judge makes the final decision on matters before the court, and we cannot promise a result or release time. A separate hold or sentence can prevent release even when a bond is posted. Willful violations are treated differently from an honest mistake, so tell us promptly when a problem arises.

Frequently Asked Questions
Is jail worse than prison?
It depends on the facility and the person. Some firsthand accounts describe jail as more chaotic because of turnover, uncertain case outcomes, and limited routine. Prison brings its own dangers and much longer separation. Neither label establishes the conditions someone will experience.
Do you go to jail before prison?
Many people sentenced to California state prison spend time in local custody before transfer. Others remain out of custody during part or all of their case until the court orders otherwise. Arrest, pretrial detention, conviction, and a prison commitment are separate stages.
Can you bail someone out of prison?
An ordinary bail bond does not end a prison sentence. California law does provide for release after conviction in specified circumstances under Penal Code sections 1272 and 1272.1, including rules for release pending an appeal. A lawyer must evaluate that separate question. Someone in a county jail may also be serving a sentence or subject to a hold that ordinary bail cannot resolve.
Who runs jails and who runs prisons?
Most California county jails are run by sheriffs, with exceptions such as Napa’s separate corrections department. CDCR runs California state prisons. The federal Bureau of Prisons operates federal institutions and some detention centers, while the U.S. Marshals Service also arranges federal pretrial detention.
What felonies go to jail instead of prison in California?
Penal Code section 1170(h) routes specified felony terms to county jail, subject to statutory exclusions. The offense’s sentencing provision, relevant history, registration requirements, and other rules matter. It is inaccurate to assume that every nonviolent felony qualifies or that every felony requires state prison.
How long can you stay in county jail?
It depends on the basis for custody. A person might be released shortly after booking, held while a case proceeds, or serve a local sentence. California allows certain felony sentences to be served in county jail for more than a year. A national average stay is not a maximum or an individual release estimate.
What is the difference between a jail, a penitentiary, and a detention center?
"Correctional facility" is a broad term. "Penitentiary" generally refers to a prison, while "detention center" can refer to a pretrial, juvenile, immigration, or other custody facility. The name alone is not enough to establish who runs it or why someone is held there.
What is the difference between state prison and federal prison?
State prisons generally hold people sentenced under state law, while federal prisons generally hold people sentenced for federal offenses. California contains both kinds of facilities. A federal case follows federal release and sentencing procedures, so California county bail practices should not be assumed to apply.
Are there places without county jails?
Yes. Alpine County contracts for jail services outside the county, and some states combine jail and prison functions within a state agency. This changes administration and placement. It does not mean people cannot be detained or that every local holding facility disappears.
Do other countries have the same jail and prison distinction?
Not always. Norway manages pretrial and sentenced custody within its correctional service, while Canada divides responsibility partly by sentence length. Countries may use "prison" for buildings that also hold people awaiting trial. Check the legal status and responsible agency rather than relying on the English name.
Does posting bail mean someone will avoid a prison sentence?
No. Bail concerns release while legal proceedings continue, subject to applicable law and the court’s orders. It does not decide guilt, dismiss charges, or determine the sentence. Defense counsel handles those issues.
Which California jails and prisons are the worst?
Our guides to California’s worst county jails and state prisons with documented problems examine audits, court records, and other dated evidence. They are editorial assessments, not official safety ratings. Conditions and individual experiences can vary within a facility.
