Viru Prison in Estonia A prison (from Old French prisoun)1 is a place in which people are physically confined and, usually, deprived of a range of personal freedoms. Imprisonment or incarceration is a legal penalty that may be imposed by the state for the commission of a crime. Other terms are penitentiary, correctional facility, remand center, detention center and gaol (or jail). In the United States, "jail" and "prison" refer to separate levels of incarceration; generally speaking, jails are county or city administrated institutions which house both inmates awaiting trial on the local level and convicted misdemeanants serving a term of one year or less, while prisons are state or federal facilities housing those awaiting trial on the state or federal level and convicted felons serving a term of more than one year. On the federal level, this terminology has been largely superseded by a more complex five-tier system implemented by the Federal Bureau of Prisons that ranges from low security "Prison Camps" to medium security "Correctional Institutions" and finally maximum security "Penitentiaries". An outer view of Administrative Block of Central Jail Faisalabad, Pakistan in 2010 A criminal suspect who has been charged with or is likely to be charged with criminal offense may be held on remand in prison if he is denied or unable to meet conditions of bail, or is unable or unwilling to post bail. A criminal defendant may also be held in prison while awaiting trial or a trial verdict. If found guilty, a defendant will be convicted and may receive a custodial sentence requiring imprisonment. As well as convicted or suspected criminals, prisons may be used for internment of those not charged with a crime. Prisons may also be used as a tool of political repression to detain political prisoners, prisoners of conscience, and "enemies of the state", particularly by authoritarian regimes. In times of war or conflict, prisoners of war may also be detained in prisons. A prison system is the organizational arrangement of the provision and operation of prisons, and depending on their nature, may invoke a corrections system. Although people have been imprisoned throughout history, they have also regularly been able to perform prison escapes.

(May 2010) For most of history, imprisoning has not been a punishment in itself, but rather a way to confine criminals until corporal or capital punishment was administered. There were prisons used for detention in Jerusalem in Old Testament times, and the Bible details the imprisonment of Joseph in Egypt.2 Dungeons were used to hold prisoners; those who were not killed or left to die there often became galley slaves or faced penal transportations. In other cases debtors were often thrown into debtor's prisons, until they paid their jailers enough money in exchange for a limited degree of freedom. Only in the 19th century, beginning in Britain, did prisons as known today become commonplace. The modern prisons system was born in London, as a result of the views of Jeremy Bentham. The notion of prisoners being incarcerated as part of their punishment and not simply as a holding state until trial or hanging, was at the time revolutionary. Britain practiced penal transportation of convicted criminals to penal colony in the British colonies in the Americas, from the 1610s through the American Revolution in the 1770s and to penal colonies in Australia between 1788 and 1868. France sent criminals to tropical penal colonies including Louisiana in the early 18th century.3 Penal colonies in French Guiana operated until 1951 (in particular, infamous Île du Diable (Devil's Island)). Katorga prisons were established in the 17th century in Tsardom of Russia in underpopulated areas of Siberia and the Russian Far East that had few towns or food sources. Since these times, Siberia gained its fearful connotation of punishment. Design and facilities The main entrance to the Utah State Prison Barbed tape is a feature of prisons. A modern jail cell

Male and female prisoners are typically kept in separate locations or separate prisons altogether.4 Prison accommodation, especially modern prisons in the developed world, are often divided into wings. A building holding more than one wing is known as a "hall". Many prisons are divided into two sections, one containing prisoners before trial and the other containing convicted prisoners. Amongst the facilities that prisons may have are: A main entrance, which may be known as the 'gatelodge' or 'sally port' (stemming from old castle nomenclature) A religious facility, which will often house chaplaincy offices and facilities for counselling of individuals or groups An 'education facility', often including a library, providing adult education or continuing education opportunities A gym or an exercise yard, a fenced, usually open-air-area which prisoners may use for recreational and exercise purposes A healthcare facility or hospital A segregation unit (also called a 'block' or 'isolation cell'), used to separate unruly, dangerous, or vulnerable prisoners from the general population, also sometimes used as punishment (see solitary confinement) A section of vulnerable prisoners (VPs), or protective custody (PC) units, used to accommodate prisoners classified as vulnerable, such as sex offenders, former police officers, informants and those that have gotten into debt or trouble with other prisoners A section of safe cells, used to keep prisoners under constant visual observation, for example when considered at risk of suicide A visiting area, where prisoners may be allowed restricted contact with relatives, friends, lawyers, or other people A death row in some prisons, a section for criminals awaiting execution A staff accommodation area, where staff and corrections officers live in the prison, typical of historical prisons A service/facilities area housing support facilities like kitchens Industrial or agricultural plants operated with convict labour A recreational area containing items such as a TV and pool table A corrections officer in Finland Prisons are normally surrounded by fencing, walls, earthworks, geographical features, or other barriers to prevent escape. Multiple barriers, concertina wire, electrified fencing, secured and defensible main gates, armed guard towers, lighting, motion sensors, dogs and roving patrols may all also be present depending on the level of security. Remotely controlled doors, CCTV monitoring, alarms, cages, restraints, nonlethal and lethal weapons, riot-control gear and physical segregation of units and prisoners may all also be present within a prison to monitor and control the movement and activity of prisoners within the facility. Modern prison designs have sought to increasingly restrict and control the movement of prisoners throughout the facility while permitting a maximal degree of direct monitoring by a smaller corrections staff. As compared to traditional large landing-cellblock designs which were inherited from the 19th century and which permitted only intermittent observation of prisoners, many newer prisons are designed in a decentralized "podular" layout. Smaller, separate and self-contained housing units known as "pods" or "modules" are designed to hold between sixteen and fifty prisoners each and are arranged around exercise yards or support facilities in a decentralized "campus" pattern. A small number of corrections officers, sometimes a single officer, is assigned to supervise each pod. The pods contain tiers of cells arranged around a central control station or desk from which a single officer can monitor all of the cells and the entire pod, control cell doors and communicate with the rest of the prison. Pods may be designed for high-security "indirect-supervision", in which officers in segregated and sealed control booths monitor smaller numbers of prisoners confined to their cells. An alternative is "direct-supervision", in which officers work within the pod and directly interact with and supervise prisoners, who may spend the day outside their cells in a central "dayroom" on the floor of the pod. Movement in or out of the pod to and from exercise yards, work assignments or medical appointments can be restricted to individual pods at designated times and is generally centrally controlled. Goods and services, such as meals, laundry, commissary, educational materials, religious services and medical care can increasingly be brought to individual pods or cells as well. Despite these design innovations, overcrowding at many prisons, particularly in the U.S., has resulted in a contrary trend, as many prisons are forced to house large numbers of prisoners, often hundreds at a time, in gymnasiums or other large buildings that have been converted into massive open dormitories. Lower-security prisons are often designed with less restrictive features, confining prisoners at night in smaller locked dormitories or even cottage or cabin-like housing while permitting them freer movement around the grounds to work or activities during the day. Security levels

The levels of security within a prison system are categorized differently around the world, but tend to follow a distinct pattern. Most developed countries divide prisons into separate security classes depending on the inmate population and the security needed to keep them under control. Accordingly, most developed countries have classes ranging from the most secure, which typically hold violent prisoners and those judged most likely to escape, to the least, which are most often used to house non-violent offenders or those for whom more stringent security is deemed unnecessary. Below are some different examples of prison classifications from around the world. England and Wales Main article: Prison security categories in the United Kingdom In England and Wales, prisoners are assigned security classes when they are sentenced. Thus prisons are given security classifications depending on the prisoners it is designed to hold. Therefore, prisons classified as "A" would typically house prisoners assigned the "A" category during sentencing, and be designed with the level of security necessary for that class. The categories of prisoners in descending order are: Category A: prisoners are those whose escape would be highly dangerous to the public or national security. Category B: prisoners are those who do not require maximum security, but for whom escape needs to be made very difficult. Category C: prisoners are those who cannot be trusted in open conditions but who are unlikely to try to escape. Category D: prisoners are those who can be reasonably trusted not to try to escape, and are given the privilege of an open prison. Prisoners at 'D Cat' (as it is commonly known) prisons, are, subject to approval, given ROTL (Release On Temporary License) to work in the community or to go on 'home leave' once they have passed their FLED (Full License Eligibility Dates), which is usually a quarter of the way through the sentence. The British prison system is also divided into "Open" and "Closed" prisons. Categories A-C are considered "Closed" prisons as prisoners cannot be trusted to interact with society, while category D prisons are generally "Open", meaning that prisoners with a good record and who are approved can be allowed limited function in society such as home-leave or a nominal employment. United States ADX Florence is presently the only facility housing supermax units operating in the Federal Bureau of Prisons. Federal Prison Camp, Alderson, a minimum security U.S. federal prison for women Supermax: As the name implies, the custody level goes beyond Maximum by segregating the "worst of the worst" criminals and terrorists who pose a threat to national security. These inmates have individual cells and are kept in lockdown for 23 hours per day. Meals are served through "chuck holes" in the cell door, and each inmate is permitted out of their cell for one hour of exercise per day, alone. They are permitted no contact with other inmates and are under constant surveillance via closed-circuit television cameras. Administrative: Administrative security is a classification of prisons or detention centers that are for a specific purpose, such as housing mentally ill offenders. These range in levels of security from Minimum to Administrative Maximum Security (ADMAX), as in the case of ADX Florence in Colorado. Maximum: A custody level in which both design and construction as well as inmate classification reflect the need to provide maximum external and internal control and supervision of inmates primarily through the use of high security perimeters and extensive use of internal physical barriers and check points. Inmates accorded this status present serious escape risks or pose serious threats to themselves, to other inmates, to staff, or the orderly running of the institution. Supervision of inmates is direct and constant. High: The "Middle Ground" for violent crimes, High security institutions have highly-secured perimeters (featuring walls or reinforced fences), multiple- and single-occupant cell housing, the highest staff-to-inmate ratio, and close control of inmate movement. Medium: A custody level in which design and construction as well as inmate classification reflect the need to provide secure external and internal control and supervision of inmates. Inmates accorded to this status may present a moderate escape risk or may pose a threat to other inmates, staff, or the orderly running of the institution. Supervision remains constant and direct. Through an inmate's willingness to comply with institutional rules and regulations, increased job and program opportunities exist.

Close Security: Close Security prisons are institutions which house inmates too dangerous for Low Security, but who did not commit a crime worthy of incarceration in a Medium Security Facility. These prisons are rare, as most inmates fall into either "Medium" or "Low" Security Classifications. These facilities are often located in separate areas of a Low or Medium security Prison. Low: A custody level in which both the design and construction as well as inmate classification reflect the goal of returning to the inmate a greater sense of personal responsibility and autonomy while still providing for supervision and monitoring of behavior and activity. Inmates within this security level are not considered a serious risk to the safety of staff, inmates or to the public. Program participation is mandated and geared toward their potential reintegration into the community. Additional access to the community is limited and under constant direct staff supervision Minimum: The Lowest Level of Security to which an inmate can be assigned directly. This type of Prison is typically a "Prison Farm", or other work-oriented facility, and most often houses petty or "White collar" criminals. Pre-release. A custody level in which both design and construction as well as inmate classification reflect the goal of restoring to the inmate maximum responsibility and control of their own behavior and actions prior to their release. Direct supervision of these inmates is not required, but intermittent observation may be appropriate under certain conditions. Inmates within this level may be permitted to access the community unescorted to participate in programming, including but not limited to work release or educational release.

(August 2010) Giddings State School in unincorporated Lee County, Texas is a juvenile correctional facility of the Texas Youth Commission. The United States Disciplinary Barracks in Fort Leavenworth, Kansas is a military prison. Juvenile Main article: Youth detention center Prisons for juveniles (people under 17 or 18, depending on the jurisdiction) are known as young offender institutes or similar designation and hold minors who have been remanded into custody or serving sentence. Many countries have their own age of criminal responsibility in which children are deemed legally responsible for their actions for a crime. Countries such as Canada may try to sentence a juvenile as an adult, but have them serve their sentence in a juvenile facility until they reach the age of majority, at which time they would be transferred to an adult facility. Military Main article: Military prison Prisons form part of military systems, and are used variously to house prisoners of war, unlawful combatants, those whose freedom is deemed a national security risk by military or civilian authorities, and members of the military found guilty of a serious crime. Political Main article: Political prisoner Certain countries maintain or have in the past had a system of political prisons; arguably the gulags associated with Stalinism are best known. Psychiatric Main article: Psychiatric hospital Some psychiatric facilities have characteristics of prisons, particularly when confining patients who have committed a crime and are considered dangerous. In addition, many prisons have psychiatric units dedicated to housing offenders diagnosed with a wide variety of mental disorders. Rehabilitation Main article: Rehabilitation (penology) Meta-analysis of previous studies shows that prison sentences do not reduce future offenses, when compared to non-residential sanctions.5 This meta-analysis of one hundred separate studies found that post-release offenses were around 7% higher after imprisonment compared with non-residential sanctions, at statistically significant levels. Another meta-analysis of 101 separate tests of the impact of prison on crime found a 3% increase in offending after imprisonment.6 Longer periods of time in prison make outcomes worse, not better; offending increases by around 3% as prison sentences increase in length.5 Effective rehabilitation programs reduce the likelihood of re-offense and recidivism.6 Effective programs are characterised by three things: first, they provide more hours for people with known offense risk factors (the Risk Principle); secondly, they address problems and needs that have a proven causal link to offending (the Needs Principle); and thirdly, they use cognitive-behavioural approaches to behaviour modification (the Responsivity Principle). Providing rehabilitation to people at lower risk of reoffending results in a 3% reduction in reoffending, while providing rehabilitation to people with a high risk of reoffending is three times as effective, resulting in a 10% reduction in subsequent offending.6 Risk factors for reoffending are: age at first offense, number of prior offenses, level of family and personal problems in childhood and other historical factors, along with level of current needs related to offending. Those individuals who had many personal and family problems in childhood (particularly 19 or more), started offending before puberty, and have committed multiple priors are more likely to reoffend in future, according to longitudinal studies internationally.7

In support of the Needs Principle, programs that specifically target criminogenic needs (causal needs and problems), see a 19% reduction in reoffending.6 In support of the Responsivity Principle, there is a 23% reduction in reoffending after participating in programs that use cognitive-behavioural methods to bring about changes in behaviour, thinking, and relationships.6 When all three principles are effectively applied, the impact on offending is a 26–32% reduction,68 compared to a 3–7% increase in offending found with imprisonment alone. Residential approaches—whether in prison or some other live-in option—tend to be less effective than non-residential approaches.6 These researchers found that effective programs delivered in the community were followed by a 35% reduction in reoffending, whereas effective programs delivered in residential settings (such as prisons and halfway houses) were followed by a 17% reduction in reoffending. One very likely reason for this is that for teens and adults, mixing with antisocial peers increases the risk of offending. In prison or residences inmates spend a great deal of time with other people immersed in criminal pursuits and beliefs, whereas in community-based programs there is more opportunity to mix with people involved in constructive, law-abiding activities. Antisocial peers in prisons and residences can form a very powerful pressure group, subtly and not so subtly influencing the behavior of other inmates. Resocialization Rabbi Philip R. Alstat, c. 1920 Main article: Resocialization Resocialization is a sociological concept dealing with the process of mentally and emotionally "re-training" a person so that he or she can operate in an environment other than that which he or she is accustomed to. Resocialization into a total institution involves a complete change of personality. Key examples include the process of resocializing new recruits into the military so that they can operate as soldiers (or, in other words, as members of a cohesive unit) and the reverse process, in which those who have become accustomed to such roles return to society after military. Prison ministry Main article: Prison religion Rabbi Philip R. Alstat, an early champion of prison ministry who served as a chaplain for three decades for The Tombs, the Manhattan Detention Facility, described the role of prison chaplains through its link to both rehabilitation and resocialization. In a 1970 interview with a New York Times reported, he was quoted as saying, "My goals are the same as those of the prison authorities--to make better human beings. The only difference is that their means are discipline, security, and iron bars. Mine are the spiritual ministrations that operate with the mind and the heart."9 Population statistics World map showing number of prisoners per 100,000 citizens As of 2006, it is estimated that at least 9.25 million people are currently imprisoned worldwide.10 It is probable that this number is likely to be much higher, in view of general under-reporting and a lack of data from various countries, especially authoritarian regimes. In absolute terms, the United States currently has the largest inmate population in the world, with more than 2½ million11 or more than one in a hundred adults12 in prison and jails. Although the United States represents less than 5% of the world's population, over 25% of the people incarcerated around the world are housed in the American prison system. Pulitzer Prize winning author Joseph T. Hallinan wrote in his book Going Up the River: Travels in a Prison Nation, "so common is the prison experience that the federal government predicts one in eleven men will be incarcerated in his lifetime, one in four if he is black." In 2002, both Russia and China also had prison populations in excess of 1 million.13 By October 2006, the Russian prison population declined to 869,814 which translated into 611 prisoners per 100,000 population. As a percentage of total population, the United States also has the largest imprisoned population, with 739 people per 100,000 serving time, awaiting trial or otherwise detained.14 In March 2007, the United Kingdom had 80,000 inmates (up from 73,000 in 2003 and 44,000 in 1985) in its facilities, one of the highest rates among the western members of the European Union (EU) (a record formerly held by Portugal). The highest imprisonment rates among the larger EU members include that of Poland, which in August 2007 had about 90,000 inmates, i.e. 234 prisoners per 100,000 inhabitants,15 while the highest rates are in the Baltic states Estonia, Latvia and Lithuania with estimated rates of 240, 292 and 333 respectively in 2006.14

The high proportion of prisoners in some developed countries is from various causes, but the attitude toward drug-taking plays a considerable part.citation needed In undeveloped countries, rates of incarceration are often lower.citation needed In general, such societies have fewer goods to steal and a more community based social system, with less judicial law-enforcement. Also their economies may not support the high cost of incarceration.

Germany Further information: Prisons in Germany Germany has 194 prisons (of which 19 are open institutions). Official statistics showed 80,214 places on March 31, 2007. On the same day, there were 75,719 prisoners (of which 13,168 pre-trial; 60,619 serving sentences; 1,932 others, i.e. mainly civil prisoners; 4,068 were female). This is less than the highest value of 81,176 prisoners on March 31, 2003.2425 Ireland Most jails in the Republic of Ireland were built in the 19th century, including Kilmainham Gaol (no longer in use), Mountjoy Prison and Portlaoise Prison. A new €30m prison is planned at Thornton Hall to replace Mountjoy. Poland As of the end of August 2007, Poland officially declared 90,199 prisoners (13,374 pre-trial; 76,434 serving sentences; 391 others; 2,743 prisoners were female), giving an imprisonment rate per 100,000 inhabitants of about 234. The overpopulation rate (number of prisoners held compared to number of places for prisoners) was estimated by the official prison service as 119%.15

The growth rate of imprisonment in Poland during 2006–2007 was approximately 4% annually, based on the August 2007 estimate of 90,199 prisoners and the June 2005 estimate of 82,572 prisoners.26 Turkey Main article: Prisons in Turkey Prisons in Turkey are classified as closed, semi-open and open prisons. Closed prisons are separated into different kinds according to its structure and the number of prisoners held. Examples are A type, B type, E type and F type. F types are high security prisons, known in the United States as Supermax.

Further information: Incarceration in the United States See also: U.S. Bureau of Prisons In the United States penal system, a jail is a correctional institution used to detain persons who are in the lawful custody of the state, including accused persons awaiting trial and those who have been convicted of a crime and are serving a sentence of less than one year.2728 Jails are generally small penitentiaries run by individual counties and cities,28 though some jails in larger communities may be as large and hold as many inmates as regular prisons. As with prisons, some jails have different wings for certain types of offenders, and have work programs for inmates who demonstrate good behavior. Approximately half of the U.S. jail population consists of pretrial detainees who have not been convicted or sentenced. Prisoners serving terms longer than one year are typically housed in correctional facilities operated by state governments.29 Unlike most state prisons, a jail usually houses both men and women in separate portions of the same facility. Some jails lease space to house inmates from the federal government, state prisons or from other counties for profit. Number of inmates. 1920 to 2006. In 2005, a report by the Bureau of Justice Statistics found that 62 percent of people in jails have not been convicted, and are awaiting trial.30 As of 2005[update], local jails held or supervised 819,434 individuals. Nine percent of these individuals were in programs such as community service, work release, weekend reporting, electronic monitoring, and other alternative programs.28 The United States has less than 5% of the world's population31 and 23.4% of the world's prison population.32 2,304,115 were incarcerated in U.S. prisons and jails in 2008.33 In 2002, 93.2% of prisoners were male. About 10.4% of all black males in the United States between the ages of 25 and 29 were sentenced and in prison, compared to 2.4% of Hispanic males and 1.3% of white males.34 In the United States, as compared to regular 'mainline' state and federal prisons, in which prisoners have already been investigated and classified by corrections personnel before being assigned to a level of security, in which many of the prisoners are committed for longer periods of time, and in which the population is on average older, jails usually house prisoners who are on average younger and have varying or unknown histories and propensities for violence or disciplinary problems. As a result, many jails operate their booking and receiving units at a relatively high level of correctional security, and also witness a disproportionately large amount of violence and disciplinary problems as compared to mainline facilities. There are three main management styles common in most U. S. jails. The first and oldest style is Intermittent Surveillance. Intermittent Surveillance involves rows of cells along security corridors. These corridors are patrolled by staff providing periodic observation. Most problems occur between these intermittent patrols. The second supervisory style is Remote Surveillance. Remote Surveillance involves cells and their corresponding dayrooms divided into "pods" which are under constant supervision by jail staff from a central control room. Staff in the central control room commonly observe three to four "pods" at one time. The third and most recently conceived supervisory style is Direct Supervision.35 Direct Supervision involves a dayroom with numerous cells under constant and direct supervision by staff who are stationed inside the housing unit. Staff are constantly interacting with inmates and controlling inmate behavior. The success of Direct Supervision relies on the staff's ability to control this behavior and for facility management to create detention environments that facilitate the staff's effectiveness. This style is also the most cost effective of the three.35 Dorchester Penitentiary in New Brunswick, Canada, part of Corrections Canada. Opened in 1880 as a maximum security prison, it now functions as a medium security facility. Canada

The 52 penitentiaries in Canada are operated by the federal government, and are for those who have been sentenced to serve more than 2 years of custody. The boundary of two years separating provincial and federal custody underlies the sentencing of some offenders to "two years less a day", so they can serve their sentences in provincial correctional institutions.
