As a matter of policy, the French government does not collect data on
race, religion or ethnicity on its citizens in any capacity, making it
difficult to obtain precise figures on the makeup of prison populations.
But demographers, sociologists and Muslim leaders have compiled
generally accepted estimates showing Muslim inmate populations
nationwide averaging between 60 and 70 percent.
In Britain,
11 percent of prisoners are Muslim in contrast to about 3 percent of
all inhabitants, according to the Justice Ministry. Research by the Open
Society Institute, an advocacy organization, shows that in the
Netherlands 20 percent of adult prisoners and 26 percent of all juvenile
offenders are Muslim ; the country is about 5.5 percent Muslim. In
Belgium, Muslims from Morocco and Turkey make up at least 16 percent of
the prison population, compared with 2 percent of the general populace,
the research found.
Ce qui est incroyable c’est la comparaison d’ordre de grandeur avec nos voisins.
