`nta_acs_data.Rd`

A dataset containing U.S. Census Bureau American Community Survey (ACS) estimates and margins of error of selected demographic, social, and economic variables for all neighborhood tabulation areas (NTAs) in New York City. Variables are five-year tract-level estimates from the 2013-2017 ACS aggregated to NTAs. Six of the 195 NTAs cover parks, cemeteries, and airports and do not have any population. They are not included in this dataset.

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.
