As your report states, the 2008 numbers come from a listing that only includes apartment that are being advertised for rent. So, using your Carroll Gardens/Park Slope example, the median for all apartments that were occupied is $1,090. This includes rent stabilized tenants who have been there for years. It does not include any apartments that are available for rent at current market prices.
