Every year, Chicago Agent magazine publishes Real Data, a residential reference book that provides realty professionals with important stats about the previous year and helps with planning business for the current year. Our most recent book included information gathered from January 2010 through October 2010, though real estate professionals  referred back to the valuable stats throughout 2011. Here were the statistics that proved the most popular with Chicagoland Realtors in 2011, and be sure to check back in the first week of January for Real Data statistics from 2011:
