A simple features (sf) dataset containing the geometry of all neighborhood tabulation areas (NTAs) in New York City.
An sf object with 195 rows and 10 variables:
NYC neighborhood tabulation area id
NYC neighborhood tabulation area name
ANSI state FIPS code
ANSI county FIPS code
NYC DCP borough code and census tract number
Census Bureau public use microdata area id
Census Bureau public use microdata area name
NAD83 / New York Long Island (ftUS); EPSG:2263
Neighborhood tabulation areas (NTAs) were created by the NYC Department of City Planning to project populations at a small area level. The boundaries roughly match neighborhoods, but some neighborhoods were combined to reach the minimum population of 15,000 per NTA. Each NTA was created from whole census tracts to allow for aggregating census data to the NTA level. Additionally, NTAs do not cross public use microdata area (PUMA) boundaries.
NTAs are useful geographies because they offer a compromise between very small areas like census blocks or tracts and larger areas like counties, community districts, or PUMAs. Especially when using data from the American Community Survey, NTAs can be useful to reduce the margin of error of single census tract estimates.
