The U.S. spends more on prisons and jails than it does on educating children – and 15 states spend at least $27,000
more per prisoner than they do per student, according to a new report.

Americans account for 4.4 percent of the global population, but 22 percent of the world’s prison population.

California spends $8.6 billion a year on its prison system, more than any other state, averaging $64,642 per inmate. It’s also the state with the biggest gap between education and prison spending, paying just $11,495 per student for a difference of $53,146, according to a new analysis by personal finance site GoBankingRates.

Several factors play into the imbalance, including U.S. incarceration rates, which have more than tripled over the past three decades – even as crime rates have fallen. During the same period, government spending on K-12 education increased by 107 percent, according to a report by the U.S. Department of Education

Another factor in the spending gap between education and incarceration is that it takes more workers to run a prison than a school, with each American teacher supervising an average of 20.8 students, while prison guards oversee an average of 5.3 prisoners.

In addition, it costs more to house and feed prisoners three times a day, compared to school children who do not require the same 24-hour oversight.

While it may seem that prison spending and education spending are disparate, experts have drawn correlations between the two.

For example, about 66 percent of state prison inmates haven’t graduated high school, and young black men aged 20-24 without a high school diploma are more likely to be in jail or prison than they are to have a job, according to the U.S. Department of Education.

New York had the second-largest gap between per student and per prisoner costs – and spends more on each than any other state. Spending per student in New York is $22,366, compared to the $69,355 it invests per inmate, for a difference of $46,989.

Connecticut follows, with a $43,202 gap between its $18,957 spending per student and $43,201 per inmate costs.

New Jersey narrowly ranks fourth, with a $43,201 gap between per student spending ($18,402) and per inmate expenditures ($61,603).

Rhode Island lands in fifth place, with a $43,033 gap when comparing per student spending ($15,531) to costs per inmate ($58,564).
