New York City Projection Areas
Data Format:
ESRI Shapefile
File or table name:

Data Projection:

Coordinate system:

Theme keywords:
boundary, borough, boundaries
Abstract:
These projection areas were created to project populations at a small area level, from 2000 to 2030. First and foremost, these aggregations were driven by population size in 2000 – projection areas had to have a minimum population of 15,000, because this reduces the error associated with the projected population. This criterion resulted in combinations of neighborhoods that probably would not occur if one were solely designating boundaries of historical neighborhoods. Moreover, the neighborhood names associated with the projection areas are not intended to be definitive.
Projection areas were created using whole census tracts that were exact subdivisions of New York City’s 55 Public Use Microdata Areas (PUMAs). (PUMAs were developed for use with the Census Bureau’s Public Use Microdata Samples (PUMS) and are approximations of Community Districts.) Projection areas were not permitted to cross PUMA boundaries.
Users need to be cognizant of the reason why these projection areas were created, and the demographic and geographic constraints inherent in how they were configured.

- Abstract:
- These projection areas were created to project populations at a small area level, from 2000 to 2030. First and foremost, these aggregations were driven by population size in 2000 – projection areas had to have a minimum population of 15,000, because this reduces the error associated with the projected population. This criterion resulted in combinations of neighborhoods that probably would not occur if one were solely designating boundaries of historical neighborhoods. Moreover, the neighborhood names associated with the projection areas are not intended to be definitive.
Projection areas were created using whole census tracts that were exact subdivisions of New York City’s 55 Public Use Microdata Areas (PUMAs). (PUMAs were developed for use with the Census Bureau’s Public Use Microdata Samples (PUMS) and are approximations of Community Districts.) Projection areas were not permitted to cross PUMA boundaries.

- Purpose:
- These boundaries were created by the Department of City Planning for assessing small area population projections.
