Area & Neighborhood Boundary Data

Spatial Data. Visually Mapped. Precise Location.

Largest Database of Spatial Data for Access to Area & Neighborhood Boundaries

ATTOM now offers the largest database ever compiled for area and neighborhood boundaries.

Our area and neighborhood boundary data covers the entire U.S., which includes more than 502 metros, 328,356 residential subdivisions, and 40,878 neighborhood boundaries.

How Area & Neighborhood Boundary Works

It starts with a hierarchy of macro-neighborhoods, neighborhoods, and sub-neighborhoods.

It’s defined by multiple authoritative sources such as local government, real estate, tourism, local media and customer feedback.

Hand-digitized area boundaries that are unambiguous and non-overlapping are added, which results in more accurate search and cleaner visualizations in analysis.

ATTOM delivers your data in an industry-standard geographic information system (GIS) format called shapefiles, which are refreshed quarterly.


Boundaries File

Contains the base-level content required to search for and display the geographic boundary. Presents the boundaries on a map and used within a database to determine specific point using longitude and latitude.


Relationship File

Contains a series of relationships among and between boundaries. Indicates if boundaries overlap each other, are near each other or are wholly contained within each other.


Attribute File

Contains value-added content about the geography that you can interact with for analysis and display purposes like population, family size, school address information and more. Also contains linking keys back to the boundaries.


Hierarchy File

Typically includes hierarchical or “nesting” relationships among boundaries. Explains any nesting hierarchy of any boundaries that have a “within” relationship.


Geo Lookups

Contains information about the relationships between any geographic boundaries you may license. Lookups are standardized to provide better usability and improved information.
