The Planning Database (PDB) contains select 5-year ACS estimates, 2010 Census operational variables, and the Low Response Score (LRS). The LRS is the predicted percent of households that will not self-respond in a given block group or census tract. New to the 2019 PDB are ACS 5-year internet access statistics and 5-year ACS self-response rates at the tract level.
The Response Outreach Area Mapper (ROAM) is an interactive mapping application, developed to make it easier to identify hard-to-survey areas and the socioeconomic and demographic profiles of those areas. It is based on a subset of PDB data at the census tract-level, including the LRS, poverty status, education level, race, Hispanic origin, and language spoken at home.
