can someone do the math?

it seems to me, that with 30 in and 45 out a day, less than 1% recidivism, and some 21,000 currently being held, that we are talking a large percentage of iraqis have either been held in prison by the usa, or have someone in their family who has, over the past 4 years. (One of the crimes for which Saddam Hussein was rightly decried was the massive use of incarcerations.)

• BAGHDAD — The U.S. military said Saturday it has released more than 10,000 detainees in Iraq so far this year _ more than in all of 2007 _ as it continues to try phase out its running of Iraqi prisons.
• The military said about 21,000 people remained in custody, and it is currently releasing about 45 detainees and detaining 30 a day.("More than 10,000 detainees released in Iraq,"by SELCAN HACAOGLU, AP, August 2, 2008)
