How was density measured for each site?
Using the 2000 Census and a street mapping software program, we measured the density in units per acre for each site. With online access to Census 2000 data, calculating density proved a relatively straightforward task (click here for a step-by-step description of the process). Once block level data were downloaded, we divided the number of housing units by the acreage of the selected areas to determine a unit per acre number.
