Local jails in the United States experienced a large decline in their inmate populations from June 30, 2019 to June 30, 2020, which can be attributed mainly to the COVID-19 pandemic. The inmate population confined in local jails was 549,100 at the end of June 2020, down from 734,500 at the end of June 2019. The midyear 2020 inmate population was the lowest since 1996, when 518,500 inmates were confined in local jails (not shown in tables).
