Map Reliability Calculator

How error prone is your map? If you’re mapping American Community Survey (ACS) data, then our Map Reliability Calculator will help guide you in the creation of statistically reliable map categories.

Map Reliability Calculator (2.5k geo limit — faster)

Map Reliability Calculator (75k geo limit — slower)

For examples of how to use the Map Reliability Calculator, see case study #2 in the U.S. Census Bureau’s ACS Handbook on What State and Local Government Users Need to Know.

Watch our presentation to the Centers for Disease Control and Prevention (CDC) for a broad overview of issues related to mapping ACS data and background on the Map Reliability Calculator.
