The NYC Planning Department's American Community Survey (ACS) update to the NYC Census Factfinder (NYC CFF) application has just been released. It is now possible to get 2009-2013 ACS profiles for Neighborhood Tabulation Areas and user defined census tract aggregations, in addition to demographic profiles from the 2000 and 2010 censuses. The ACS profiles include basic count estimates, but also percentages, means, and median estimates for custom geographies. Another key benefit of this update is that detailed statistical reliability information, including Margins of Error and Coefficients of Variation, are available for user-defined geographies. Additionally, data with poor statistical reliability are shown in gray as an alert to users.
