Variable General Info
College educated residents (greened vacant lots) ?Comment:From Geolytics Incorporated (East Brunswick, New Jersey) and the US Census Bureau (Washington, DC), we obtained block group-level estimates of demographic variables for each year of the study. Education was defined in terms of the number of residents aged 25 years or older who had completed at least some college. Education at the block group level was partitioned among greened lot and control sites. |
