2010 Geographies
Table G-1	Table G-1: New York City 2000 Census Tracts with Boundary/Number Changes (involving block pop) For 2010 Census
NTAs (Names & Codes) NTAs (Tracts & Streets)	Maps of Neighborhood Tabulation Areas (NTAs). Neighborhood Tabulation Areas, or NTAs, are aggregations of census tracts that are subsets of New York City's 55 Public Use Microdata Areas (PUMAs). Primarily due to these constraints, NTA boundaries and their associated names may not definitively represent neighborhoods.
PUMA/ Community District Map	A map showing the relationship between Public Use Microdata Areas (PUMAs) and Community Districts (CDs). The 55 Census designated PUMA subareas approximate New York City’s Community Districts and are not coterminous. The Census Bureau sets a minimum PUMA population requirement at 100,000 persons.
Census Tract/ NTA/PUMA Equivalencies	A file that shows the relationship between 2010 census tracts, Neighborhood Tabulation Areas (NTAs), and Public Use Microdata Areas (PUMAs).
