American Community Survey (ACS) data is available in Business Analyst Online (BAO) and Community Analyst via the color-coded maps and Smart Map Search. Users can thematically display the ACS estimates, then apply the Reliability toggle in the map legend to view the estimates' associated reliability. Colors used for shading the maps are the same as the colors of the reliability symbols. To better understand the data, users can also view the value of the ACS estimate, the ACS margin of error, and the coefficient of variation for selected geographies. The coefficient of variation is used to determine the reliability of the estimate.
