…Not available. Specific type of capacity is not measured by state.
/Not reported.
a/Population counts are based on the number of inmates held in custody of facilities operated by the jurisdiction. Excludes inmates held in local jails, other states, or private facilities unless otherwise stated. Lowest capacity represents the minimum capacity estimate submitted by the jurisdiction, while highest capacity represents the maximum capacity estimate. When a jurisdiction could only provide a single capacity estimate, it was used as both lowest and highest capacities.
b/Due to differences in the dates when data were extracted, the federal custody count reported for the calculation of capacity includes 258 inmates compared to the yearend custody reported in National Prisoner Statistics (NPS).
c/State defines capacity in a way that differs from BJS’s definition. See Jurisdiction notes.
d/State did not report 2015 capacity data to NPS. Estimates derived from a report to the state legislature and represent 2014 capacity. See Methodology.
e/Private facilities included in capacity and custody counts.
f/State has changed reporting methodology, so 2015 custody counts are not comparable to those published for earlier years.  See Jurisdiction notes for details.
g/Both capacity and custody counts exclude inmates in community-based work release facilities.
h/Capacity estimate includes some beds used for pretrial inmates not reflected in custody count.
i/State did not submit 2015 NPS custody or capacity data.
j/State did not submit 2015 NPS capacity data. Estimates are from 2014. See Jurisdiction notes.
