What is a Private Prison?

A private prison, also known as a for-profit prison, is a place where individuals are physically confined or incarcerated by a third party that is contracted by a government agency. Private prisons are operated by private prison companies purely for profit, unlike public prisons which are managed by the government.

The operation of private prisons is controversial, with proponents arguing they provide cost savings and flexibility while critics argue they have misaligned incentives and are associated with higher levels of violence. Below is an overview of how private prisons function in the United States:

History of Private Prisons

  • The origins of private prisons in the US date back to the 1980s. Facing capacity issues and rising costs, some state governments began exploring the idea of outsourcing prisons.
  • The first modern private prison in the US opened in 1984 in Tennessee. It was operated by the Corrections Corporation of America (CCA), now known as CoreCivic.
  • Through the 1990s and 2000s, the number of people incarcerated in the US grew rapidly, fueled in part by stricter drug policies. This increased demand for prisons.
  • By the late 1990s, over a dozen states had contracted with CCA or other companies to operate private prisons. The federal government also began using them.

How Private Prisons Operate

  • Private prison companies build their own facilities or lease/purchase existing prisons from state governments to operate.
  • Major companies like CoreCivic and GEO Group operate hundreds of private prison facilities around the US.
  • They contract with government agencies (states, federal Bureau of Prisons) to house their prisoners, charging a per diem rate per prisoner.
  • Private prison contracts typically specify expected services/performance metrics like staffing levels, programming, healthcare, food, policies, etc.
  • Government oversight varies but private prisons must follow major regulations like constitutional protections for inmates.

Use and Growth of Private Prisons

  • Today approximately 8% of US prisoners are held in private prisons – around 115,000 inmates.
  • The federal system has the highest percentage (over 25%) housed in private prisons. Most states have at least some contracts.
  • Private prisons saw steady growth, until stabilizing around 2015. But the trend may be reversing – California is phasing them out completely.
  • The two largest companies, CoreCivic and GEO Group, earn billions in annual revenue and wield significant lobbying influence. But their stocks have struggled recently.
  • While growth has slowed, private prisons won’t disappear overnight given existing contracts. But debates continue around their appropriate role.

Pros and Cons of Private vs Public Prisons

There are various arguments made for and against the use of private prisons compared to publicly operated facilities. Below are some of the main pros and cons:

Potential Advantages of Private Prisons

  • Cost savings – Private prisons can provide operational cost savings, through economies of scale and efficiency measures. Avoiding public employee pensions/benefits also lowers costs.
  • Flexible capacity – Private companies can build new prisons faster than governments to add capacity quickly. Unused facilities can also be repurposed or sold off.
  • Performance incentives – Contracts can include penalties, bonuses, etc. to incentivize private prisons to meet specific performance metrics. This can promote efficiency.
  • Innovation – Private companies may be more willing to experiment with new technologies, managerial tactics, prisoner programs, that could improve quality and lower costs.

Potential Disadvantages of Private Prisons

  • Misaligned incentives – For-profit prisons generate revenue by cutting costs and filling beds. This could incentivize them to inappropriately skimp on quality, lobby for stricter policies, etc. to maximize profits.
  • Accountability – Lack of public oversight makes it harder to monitor conditions, safety, quality of care and ensure proper treatment of inmates.
  • Cherry-picking – Private prisons often house only the healthiest, best behaved inmates to keep costs down. Public facilities take on the most challenging populations.
  • Staffing & safety – Private prisons often have lower staffing ratios and significantly higher rates of violence, escapes, contraband, etc. High turnover also undermines safety.
  • Lack of transparency – Private companies consider facts like operational costs, security issues, lawsuits etc. proprietary information, avoiding public scrutiny.
  • Cutting corners – To maximize revenue, private prisons may cut back on critical services like healthcare, food quality, rehabilitation programs, staff training, facility maintenance and more.

Key Statistics on Private vs Public Prisons

How do private prisons really compare to publicly run facilities on issues like costs, capacity, safety and more? Here are some key statistics:

Measure Private Prisons Public Prisons
Average daily cost per inmate $60.10 $63.41
Occupancy rate 90% 95-110%
Average salary for guards $31,159 $56,820
Escapes per 10,000 prisoners 3 2
Deaths per 100,000 prisoners 153 128
Assaults per 1,000 prisoners 49 18

Key takeaways:

  • Daily costs are comparable, with private prisons having a slight edge. Though some dispute these figures.
  • Private prisons operate with less overcrowding. But critics argue they cherry-pick inmates.
  • Staffing costs are much lower, with 50% less spent on salaries in the private sector. But this leads to safety issues.
  • Assault rates are nearly 3X higher in private facilities. Death and escape rates show similar trends.
  • Overall, the data indicates serious quality and safety issues in many private prisons.

Leading Private Prison Companies

While dozens of private companies operate correctional and detention facilities in the US, two dominate the market:


  • Formerly Corrections Corporation of America, one of the first modern private prison firms
  • Manages over 50 private prisons with capacity for ~80,000 inmates, plus other detention centers
  • Generates over $1.9 billion in annual revenue, about half from state contracts
  • Has faced numerous lawsuits and scandals over violence, understaffing, contraband and poor conditions

GEO Group

  • Major competitor to CoreCivic, operates 64+ facilities with ~75,000 beds
  • 72% of revenue (~$2.2 billion) comes from federal contracts, 25% from states
  • Also faces many controversies – poorly run facilities, complaints of mistreatment, legal violations
  • Based in Florida, politically active with significant lobbying clout

While smaller firms exist, these two giants dominate the private prison industry in America. Both continue aggressively pursuing new government contracts, though facing more legal and political pushback.

Private Detention Centers for Immigrants

Private prisons also operate immigration detention facilities for ICE (Immigration and Customs Enforcement):

  • Over 70% of ICE detainees are held in private detention centers and county jails under contract.
  • CoreCivic and GEO Group are major operators of these facilities which generate lucrative per diem revenue.
  • Immigration detention is reported to be even more profitable than criminal incarceration for private prison companies.
  • There have been frequent complaints about poor conditions, lack of medical care, deaths in custody, and other abuses.
  • Under the Biden administration, long-term plans for immigration reform could reduce reliance on private detention. But capacity is still strained under current policies.

Arguments Around Prison Privatization

The debate around private vs public prisons provokes passionate arguments on both sides. Below are some of the key positions:

Arguments Supporting Prison Privatization

  • Creates competition and market pressures to encourage both private and public prisons to innovate and lower costs
  • Provides governments greater flexibility to add/reduce capacity quickly as needs change
  • Shifts financial risk and administrative burdens from taxpayers to private operators
  • Increases accountability via market competition and performance-based contracts
  • Private sector experience translates to more efficient operations and corrected misconduct

Arguments Against Prison Privatization

  • Fundamental civic duties like incarceration should never be delegated to for-profit companies
  • Cost cutting incentives lead private prisons to sacrifice quality, safety and humane treatment
  • Lack of transparency and oversight accountability in private facilities
  • No convincing evidence that privatization translates to real cost savings or innovative practices
  • Creates unethical financial incentives to lobby for policies/laws that maximize incarceration
  • Contributes to overall rise of the prison industrial complex focused on punishment over rehabilitation

Oversight Issues with Private Prisons

A major concern around private prisons is the comparative lack of oversight and accountability to the public. Some key issues include:

  • Monitoring – Most state/federal contracts do not provide enough resources for agencies to regularly monitor conditions and operations in private prisons. And companies provide minimal internal data.
  • Transparency – Unlike public prisons, private facilities are not subject to freedom of information laws. They avoid sharing details on finances, incidents, lawsuits, practices etc.
  • Policy influence – Private prison companies leverage lobbying and campaign contributions to shape laws and policies around sentencing, drugs, immigration etc. that maximize profits.
  • No independent monitoring – External research, oversight and investigations from independent entities like non-profits, journalists etc. is very limited due to lack of access.
  • Toothless regulators – Even when violations are found via lawsuits, fines or contract penalties, private prison companies have minimal accountability beyond risking that specific contract.

Stronger regulatory frameworks have been proposed – from partnering with watchdog groups to introducing robust transparency laws targeting prison contractors. But so far, the industry has successfully opposed or watered down most reform efforts.

Failures and Controversies

Private prison operators claim their facilities offer comparable services and conditions to publicly managed prisons. But in reality, major issues with private prisons have frequently emerged:

Understaffing and Staff Misconduct

  • To cut labor costs, private prisons often operate with inadequate staffing levels, leading to decreased safety and increased violence.
  • Insufficient training and high turnover rates also undermine professionalism. Low wages may encourage staff misconduct and corruption.

Health and Safety Issues

  • With prisoners having no choice, private operators may cut corners on essentials like health care, food, sanitation, maintenance and rehabilitation services.
  • Assault rates against inmates and guards are much higher in private facilities along with contraband, riots and escapes.

Poor Conditions and Abuse

  • Numerous lawsuits, fines, contract cancellations and federal reports have cited private prisons for overcrowding, abuse of inmates, poor living conditions and use of force violations.

High Profile Scandals

  • Some examples include the “Kids for Cash” scheme of judges receiving kickbacks for youth convictions, massive riots in facilities run by CCA, negligent deaths and many sexual abuse cases.

Despite claims to the contrary, the empirical evidence indicates serious systemic issues in quality, safety, and humane treatment within the private prison industry.

The Future of Private Prisons

Private prisons are at a potential inflection point in the US:

Declining Growth Trends

  • After years of expansion, the number of inmates in private prisons has stabilized since 2015.
  • Several states including California, Illinois, New York and Nevada have banned or are phasing out private prisons and detention centers. Others may restrict their use.
  • Faced with declining occupancy and stagnant stock prices, GEO Group and CoreCivic are under pressure to justify their business models.

Federal Policy Changes

  • Under the Obama administration, the DOJ moved to end all federal private prison contracts. This reversal was later rescinded under President Trump.
  • With the Biden administration, federal policies like criminal justice reform and reduced immigration detention could substantially cut demand for private beds.

Pushback and Activism

  • Ongoing activism, shareholder resolutions, divestment efforts, political lobbying etc. by civil rights groups aims to sway private prison policies and shut down contracts.
  • Major banks have faced pressure to stop lending to GEO Group and CoreCivic. These financing challenges could threaten their financial viability.

While entrenched lobbying power and existing contracts provide some protection, the environment for private prisons is clearly growing more hostile. But how rapidly the industry shrinks depends on the interplay of grassroots activism, political winds, and public sentiment in coming years.

Questions and Answers on Private Prisons

What are the key arguments for private prisons?

The main arguments made in favor of private prisons are:

  • They provide cost savings compared to public prisons
  • They can add capacity quickly and flexibly scale up or down
  • They shift certain financial risks away from taxpayers
  • They encourage performance improvements through competition
  • They leverage private sector innovation and efficiency

However, many dispute these claimed benefits in practice.

How do private immigration detention centers differ from criminal prisons?

While also run for profit, immigration detention centers tend to:

  • Hold people awaiting hearings or deportation, not serving criminal sentences
  • Have even less oversight and poorest conditions due to less regulation
  • Generate higher profit margins for operators through federal contracts
  • Face increased scrutiny for issues like deaths in custody, abuse, lack of healthcare etc.

What alternatives exist besides private or standard public prisons?

Potential alternatives models include:

  • More focus on rehabilitation and vocational programs to reduce recidivism
  • Community-based alternatives like probation, restorative justice, counseling, electronic monitoring etc.
  • Public-private partnerships to maintain government oversight while utilizing private financing
  • Government-owned facilities operated by private contractors in a hybrid model
  • Sentencing reform, decriminalization of nonviolent offenses, diversion programs and other ways to reduce prison populations overall

How viable are proposals to improve private prison oversight?

While proposals exist, improving oversight faces challenges given the industry’s significant resources and political influence. Potential reforms include:

  • Requiring detailed public reporting from private contractors on finances, conditions, incidents etc.
  • Independent monitoring of facilities by watchdog non-profits
  • Restricting lobbying by prison companies to avoid self-serving influence on laws
  • Increased fines, penalties and contract termination triggers to incentivize compliance
  • More resources for regulators to regularly audit conditions and enforce standards

Could private prison companies adapt their business models if incarceration declines?

Faced with declining prison populations, private prison firms could potentially:

  • Diversify into related markets like parole management, electronic monitoring, rehabilitation providers etc.
  • Increase focus on detention for the immigration and customs enforcement market
  • Expand in overseas markets if opportunities arise
  • Sell off assets and return value to shareholders

However, fundamentally changing their business models could threaten profitability while facing public and political backlash.


In summary, private prisons are controversial facilities operated by for-profit companies under contract with governments to incarcerate inmates. While proponents argue they reduce costs and add flexibility, critics cite evidence of misaligned incentives leading to significant quality and safety issues. With an inflection point seemingly reached, the future direction of the industry remains uncertain and will hinge on political currents, public attitudes, and the success of reform efforts targeting transparency, accountability and oversight. But the role of private prisons continues to provoke heated debate around privatization, justice, rehabilitation and the broader American criminal justice system.
