Criminal Justice Expenditures: Police, Corrections, and Courts
Police expenditures include spending on police, sheriffs, state highway patrols, and other governmental departments charged with protecting public safety.
Corrections expenditures are for the operation, maintenance, and construction of prisons and jails, as well as the activities of probation officers and parole boards.
Courts expenditures, which the Census defines as "judicial" expenditures, cover government spending on civil and criminal courts plus spending on activities associated with courts such as prosecuting and district attorneys, public defenders, witness fees, law libraries, and register of wills. It does not include probation or crime victim compensation and reparation.1

In 2017, state and local governments spent $115 billion on police (4 percent of state and local direct general expenditures), $79 billion on corrections (3 percent), and $48 billion on courts (2 percent)
Nearly all state and local spending on police, corrections, and courts in 2017 went toward operational costs such as salaries and benefits (96 percent for police and 97 percent for corrections and courts). Capital spending accounted for only 4 percent of police expenditures and 3 percent of corrections and courts expenditures.
Capital spending has never been a large share of either police or courts expenditures. From 1977 to 2017, the highest annual share of capital spending for police expenditures was 5 percent (multiple years). From 1992 to 2017, the highest share of capital spending for court expenditures was 6 percent (1997). (We do not have access to courts expenditure data for years prior to 1992.)
In contrast, capital spending on corrections, such as prison construction, was greater than 10 percent every year from 1977 to 1995. The share of capital spending on correction expenditures reached a high of 16 percent in 1988.
Most spending on police was done by local governments (87 percent) in 2017. Overall, police spending was 1 percent of state direct general expenditures and 6 percent of local direct general expenditures. State expenditures on police mostly included spending on highway patrols, while local funds supported sheriffs' offices and police departments.
Looking at specific types of local government, police spending in 2017 accounted for 13 percent of municipal direct general expenditures, 9 percent of township expenditures, and 8 percent of county expenditures.
In contrast, most direct spending on corrections was done by state governments in 2017 (62 percent). Overall, corrections spending was just over 3 percent of state direct general expenditures and a little less than 2 percent of local direct general expenditures in 2017. State spending on corrections included state-operated prisons, while local spending was concentrated on spending for county jails.
Spending on courts was equally delivered by state and local governments in 2017 (50 percent for each level). Overall, judicial spending was 2 percent of state direct general expenditures and 1 percent of local direct general expenditures. Among local governments, court spending in 2017 as a percentage of general expenditures was the highest at the county level (5 percent of county expenditures).
Nearly all state and local spending on police, corrections, and courts was funded by state and local governments because federal grants account for a very small share of these expenditures.
However, these data do not include direct federal spending on criminal justice (e.g., federal prisons). For example, the federal government directly spent $29 billion on police, $7 billion on corrections, and $15 billion on courts in 2016.
From 1977 to 2017, state and local government spending on police increased from $42 billion to $115 billion (in 2017 inflation-adjusted dollars). As a percentage of direct general expenditures, police spending has remained consistently at just under 4 percent for the past 40 years.
Over the same period, state and local spending on corrections increased from $18 billion to $79 billion (in 2017 inflation-adjusted dollars). As a percentage of direct general expenditures, corrections spending increased from 1.6 percent to 2.6 percent.
From 1992 to 2017, state and local government spending on courts increased from $29 billion to $48 billion in 2017 inflation-adjusted dollars (the court expenditure data only go back to 1992; it is not included in the graph below). Court spending as a percentage of state and local direct general expenditures remained just under 2 percent over that period.
Across the US, state and local governments spent $352 per capita on police protection in 2017. The District of Columbia3 spent the most per capita on police in 2017 at $910, followed by New York ($530), Alaska ($494), and California ($487). The lowest-spending per capita states in 2017 were Kentucky ($186), Indiana ($200), West Virginia ($217), and Arkansas ($224).
State and local governments spent $242 per capita on corrections in 2017. Alaska spent the most per capita on corrections in 2017 ($436), followed by California ($371), Wyoming ($352), and New Mexico ($343). The lowest-spending states per capita in 2017 were Iowa and Massachusetts (both $139).

In 2017, states and local governments spent $142 per capita on courts. Alaska spent the most on courts per capita in 2017 ($319), followed by Wyoming ($237) and New York ($215). The lowest spending states in 2017 were South Carolina ($73) and Arkansas ($74).
Per capita spending is an incomplete metric because it does not provide any information about a state’s demographics, policy decisions, or administrative procedures.
For example, states with high per capita spending on police tend to have high levels of spending per employee, reflecting the labor-intensive nature of police work. Thus, cost of living differences account for some of the variation in per capita spending.
Meanwhile, states with high per capita spending on corrections are a mix of states with high labor costs and large populations of individuals in local or state prisons or under parole or probation, such as Alaska or Delaware. States that spend more per capita tend to have higher costs of living, driving wages up.
However, police and corrections employees are often paid above the amount that these labor market conditions might predict. Some states with moderate per capita corrections costs, such as Georgia, compensate for a high number of people in prison, on probation, or on parole by employing fewer staff per inmate, probationer, and parolee, and by spending less per employee on payroll costs.4
There are also significant differences in police spending across localities simply because different levels of government fund police (and other services) in different states. For example, the city of Las Vegas, Nevada spent less than 2 percent of its budget on the police in 2017, but Clark County, Nevada spent 15 percent. In contrast, police spending was roughly 2 percent of the Cook County, Illinois, budget in 2017 but nearly 20 percent of the Chicago city budget. New York City spent $5.7 billion on police in 2017 but that was just 6 percent of its budget because New York City public school spending was included in the city's budget—and accounted for a third of the city’s spending.
The average spending on police for jurisdictions with more than one million people was 9.7 percent in 2017. The average for jurisdictions with fewer than 50,000 people was 16.7 percent. Again, this variation is driven in large part by what particular services jurisdictions deliver (and do not deliver).
