New data released on December 11, 2025, by the Prison Policy Initiative and the Deportation Data Project underscores the critical role that state and local governments play in shaping immigration enforcement. The report provides an in-depth look at how federal immigration authorities, particularly ICE, rely on local institutions and the private prison industry, revealing a complex network that affects thousands of individuals and communities across the nation.
Local Jails at the Heart of Federal Deportation Efforts
One of the report’s most striking findings is the heavy reliance of ICE on local jails and other municipal lock-ups. Nearly half—48%—of all ICE arrests originate from these facilities, demonstrating that federal enforcement is closely tied to local law enforcement operations. These collaborations create a pipeline in which people arrested for minor offenses, or even those merely detained pre-trial, can quickly find themselves subject to federal immigration detention and deportation proceedings.
The implications for communities are significant. Areas where local police and sheriffs actively cooperate with ICE see higher rates of arrests and detention, while jurisdictions that limit or refuse such cooperation experience far lower involvement in federal deportation actions. This dynamic shows that while immigration enforcement is federal in nature, states and localities have tangible power to influence the scope and reach of deportations.
State and Local Authority Can Mitigate Mass Deportations
The report emphasizes that states and localities are not powerless in the face of federal enforcement. Policies and laws that restrict law enforcement collaboration with ICE can dramatically reduce deportation rates. States such as Illinois, New York, and Oregon have instituted measures that limit local agencies’ ability to detain individuals on ICE’s behalf, resulting in far fewer arrests relative to states with mandated cooperation like Texas and Florida.
Such policies, sometimes referred to as “sanctuary” or “limited cooperation” measures, do more than protect individual immigrants—they also reduce the strain on local jails and prevent communities from being financially tied to federal enforcement. The report highlights that local decision-making can effectively serve as a check on ICE operations, demonstrating the tangible power of municipal governance in shaping national outcomes.
The Role of Private Detention Facilities in ICE Enforcement
A critical and often overlooked aspect of immigration detention is the involvement of the private prison industry. Nearly 90% of individuals held in ICE custody are detained in facilities operated by for-profit corporations, including major players such as GEO Group and CoreCivic. These companies are paid per detainee, per day, creating a financial incentive to maintain high detention rates.
The connection between increased ICE arrests and private profit is direct. Every detention bed filled generates revenue, which incentivizes lobbying for policies and practices that sustain or expand federal immigration detention. This model raises significant ethical concerns, as the pursuit of profit intersects with the enforcement of immigration law, shaping detention policies in ways that may not align with public interest or community well-being.
Private detention facilities also amplify the consequences of local law enforcement cooperation. When local jails are leveraged as part of ICE’s enforcement apparatus, detainees are often transferred to private facilities, linking municipal decision-making to the financial interests of corporations. The report highlights how these intertwined systems of federal enforcement, local participation, and private enterprise perpetuate a cycle of detention that impacts both human lives and public budgets.
Why This Matters for Communities and Policy
Understanding the intersection of ICE enforcement and private detention is critical for policymakers, advocates, and residents alike. Local decisions on law enforcement cooperation can shape federal deportation practices, directly affecting who is detained and for how long. Similarly, private prison operators exert influence on detention policies because their business model depends on filled beds and long-term contracts.
Communities seeking to reduce mass deportations and mitigate the human and economic costs of detention can take proactive steps. Municipal leaders can adopt policies that limit or prohibit local agencies from honoring ICE detainers. State governments can legislate oversight and transparency requirements, ensuring that federal enforcement does not create unintended financial or social burdens.

These materials help illuminate how corporate interests intersect with federal enforcement and offer guidance for communities working to prioritize justice, fairness, and humane treatment of detainees.
The Path Forward
The 2025 data on ICE arrests reinforces a simple but powerful principle: federal enforcement is shaped by local and state decisions. By understanding the systemic links between municipal jails, private detention corporations, and federal immigration policy, communities can implement strategies that protect residents, reduce unnecessary detention, and hold the private prison industry accountable. These actions not only safeguard vulnerable populations but also promote a more transparent, equitable, and humane approach to immigration enforcement.
