Jailed Population is one of the 23 indicators of peace measured by the Global Peace Index. It is an 'internal' indicator of peace, meaning it measures peace within a country.


Jailed Population is a quantitative assessment of numbers of people held in custody by the prison administration in a given year, per 100,000 people.  


Jailed Population is scored on a scale from 1 (lowest incarceration rates) to 5 (highest).

In countries that score 1, there are less than approximately 110 prisoners per 100,000 population.

In countries that score 5, there are greater than approximately 740 prisoners per 100,000 population.


Jailed Population is a quantitative assessment using data from the International Centre for Prison Studies’s World Prison Brief.
