2020 Census Tracts to 2020 NTAs and CDTAs Equivalency
This file shows the relationship between New York City’s 2020 census tracts, 2020 Neighborhood Tabulation Areas (NTAs), and Community District Tabulation Areas (CDTAs). 2020 census tracts nest within 2020 NTAs, and 2020 NTAs nest within CDTAs, so each census tract is listed only once. Note that CDTAs sometimes cross borough boundaries, and therefore will not add up to borough totals for the Bronx, Queens, and Manhattan. As they are nested within CDTAs, NTAs will likewise not add up to borough totals. Also note that census tracts in New York City’s water areas are excluded from this file.

Columns
Each source column, with the name and type we use to store it.
The publisher has not provided a data dictionary.
4 of 14 columns carry a concept; 14 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.
