Americans believe the country’s prison system is reliable at keeping inmates behind bars but falls short on reform efforts and safety, according to a new Gallup poll.

According to the Oct. 1-16 survey of 1,000 adults by Gallup, about 62% rated the nation’s prison system as “excellent” or “good” at maintaining high security.

By contrast, only 16% of respondents said the system does an excellent or good job at rehabilitating inmates so they are less likely to commit crimes in the future. Nearly eight in 10 (79%) rated rehabilitation efforts as only fair or poor.

Additionally, just 24% believe the prison system succeeds in maintaining a safe environment for inmates, while the remaining two-thirds see safety ratings as fair or poor.

The poll reports these views are strikingly similar to those recorded 25 years ago, underscoring longstanding public dissatisfaction with reform progress despite high security marks.

Demographic breakdowns show few major differences, but higher-income Americans, men and white adults tend to rate prison security more positively. Meanwhile, younger adults and people of color express slightly better views of rehabilitation-related efforts – though still low overall.
