Correctional Populations in the United
States, 2009

Lauren E. Glaze,
BJS Statistician
Correctional authorities supervised
7,225,800 offenders at yearend 2009, which
was slightly fewer offenders (down 48,800)
than in 2008 (figure 1). Correctional supervision
includes adults supervised in the community on
probation or parole and those incarcerated in state
or federal prisons and local jails. This was the first
decline (down 0.7%) observed in the total correc-
tional population since the Bureau of Justice Statis-
tics (BJS) began reporting this population in 1980.1
This report provides summary data on the correc-
tional population and highlights significant changes
in the components of the population. Also, it covers
adults supervised in the community or held in adult
correctional facilities. The total prison population
may include juveniles held in adult facilities in the
six states with combined jail-prison systems.
1See Methodology for a discussion about the sources of correc
tional data.

Note: The annual percent change in the correctional population between 1996 and 1997
and 1997 and 1998 was adjusted to account for expanded probation coverage during those
years. See Methodology for more details.

Prison populations: A comparison between the jurisdiction and custody populations

BJS's official measure of the prison population is the count of
prisoners under the jurisdiction or legal authority of state and
federal correctional officials (1,613,740 in 2009) (see appendix
table 1). These prisoners may be held in prison or jail facilities
located outside of the state or federal prison system. The prison
population reported in table 1 is the custody prison population,
which is different from the jurisdiction prison population. The
custody prison population represents the number of prisoners
physically housed in state (1,319,426 in 2009) and federal
(205,087 in 2009) correctional facilities, regardless of which
entity has legal authority over the prisoners (see appendix table
2).2 This includes state and federal prisoners held in privately

operated facilities. The difference between the custody and
jurisdiction counts is the number of state and federal prisoners
held in the custody of local jails or inmates out to court or
otherwise in transit. Because table 1 presents data on the
number of individuals under correctional supervision by
correctional status, the custody prison population is presented
instead of the jurisdiction prison population. The custody
prison population accounts for the total number of individuals
incarcerated in state or federal prisons, eliminating the
possibility of double counting individuals who may be under
the jurisdiction of one entity but who were in the custody of
another entity.
