OK someone is either making up nonsensical data or there s some obscure census data However much some of us really want Chicago to bloom I have found nothing so far demonstrating that It was estimated in 2006 that the population of Chicago was slightly over 3 million The latest census estimates put Chicago on a consistent decline and even older Illinois estimates which I had looked at before a long time ago and can t seem to find again which aren t 2006 put Chicago projected in 2006 at less than 3 million It doesn t even make sense on a theoretical level it took 10 years 1990 200 to grow by like 112k people I highly doubt that all of a sudden Chicago took that same level of growth in a little more than half that Someone find some solid data backing up that statement within the next few days or so or I ll take it out
