The Rent factfile for 2006-2007 differs from previous years in that for the first time the analysis includes 5 and 6+ bedroom sizes. In addition, as the threshold for associations required to complete the long version of the Regulatory Statistical Return (RSR) has been raised from 250 units to 1,000 the comparison this year is based on those associations with 1000+ units that completed the long RSR in both 2006 and 2007.
