Current data (2012) give a figure of 8% vacancy in a market that is 34%+ renters. This is across the board, however. Details show a very occupied downtown apartment situation and the vacancy rises as you go into certain ring areas. Take into account that the data trend lines aren't all that long. Cleveland was only begun in 2005. That said, the 2012 occupancy is the highest on record. All information was obtained from Census ACS data.
