The American Community Survey (ACS) provides data users with unique insights into the socioeconomic characteristics of local populations. Mapping the data is one way to examine differences in characteristics across geographic areas. However, ACS estimates are subject to sampling variability, so reality on the ground may differ from survey results.
In this webinar, Joel Alvarez—a Senior Demographic Analyst in the Population Division at the NYC Department of City Planning—provided guidance in mapping ACS data. He also demonstrated how to produce statistically reliable maps, using a publicly available Map Reliability Calculator. His presentation was followed by 10 minutes of Q&A.
