Incarceration Rate: We’re Number 1
The Prison Policy Initiative looked at the US incarceration rates and compared them to the founding NATO countries. Again, the United States can claim Number One status. The incarceration rate in the United States is 664 prisoners per 100,000 population. Next highest among NATO countries is the United Kingdom with 129 per 100,000, followed by Portugal (111 prisoners) and Canada (104).
