Incarceration serves to remove offenders from a community, but also creates hardships on families, including the loss of an income or a caregiver, in addition to long-term effects on mental health for all involved. After incarceration, people often encounter challenges in obtaining meaningful employment, leading to reductions in long-term productivity, recidivism and widespread effects on a community's social, health and educational systems. Disparities in this rate by race or ethnicity can highlight structural differences in how communities are affected and treated by the public safety and criminal justice system.

In 2023, African Americans in Lancaster were incarcerated at a rate of 83 persons per 10,000 residents, more than nine times the rate of 9 per 10,000 for White residents. Latinos, at 37 per 10,000 residents, were incarcerated at more than four times the rate of White residents. These disparities are larger than in Pennsylvania as a whole, where African Americans are incarcerated at nearly six times the rate of whites and Latinos at two times the rate of Whites.

Among comparison counties, Lancaster had the lowest rate of incarceration among African Americans, and the second highest rate among Latinos, behind Dauphin (43).

Disparities in incarceration are the result of racialized stereotypes, policies and practices and community conditions. Stereotypes that portray Black and Latino people, especially males, as inherently dangerous, criminal, and violent lay the foundation for police surveillance and disparate and harsher treatment by the criminal justice system. Communities of color are more likely to be under surveillance and policies such as stop and frisk perpetuate increased police contact. Punitive drug laws have had disproportionate impact on Black and Latino communities. Even though Blacks and whites have similar rates of drug use, Black people are more likely to be arrested and experience harsher sentences. In general, whites experience less harsh sentences when convicted of similar crimes as Black and Latinos. Given economic disparities, people of color are less likely to experience pre-trial release after arrest. The concentration of Black and Latino communities in highly segregated communities with limited economic opportunities and ineffective schools may also foster crime involvement.
