The Census Bureau Data API provides developers with access to a wide range of statistical data collected by the U.S. Census Bureau, facilitating integration into applications and data visualizations.
Tools
Geocode Address
Tool to geocode a single address to get latitude/longitude coordinates. Use when you need to convert a street address into geographic coordinates.
Geocode Address For Census Geographies
Geocode an address and return Census geography identifiers including state, county, tract, block group, and block FIPS codes. This tool converts a physical address into geographic coordinates and returns detailed Census geography information including FIPS codes for various geographic levels (state, county, census tract, block group, block) plus additional geographies like congressional districts, places, and statistical areas. Use this when you need to link an address to Census geographic identifiers for data analysis or geographic queries.
Geocode Address Parts
Tool to geocode an address using separate components (street, city, state, ZIP) to get latitude/longitude coordinates. Use when you have address data in separate fields rather than a single line.
Geocode Address With Geography
Tool to geocode an address and return both coordinates and Census geography information. Use when you need geographic coordinates plus Census geographic identifiers like state FIPS, county FIPS, census tract, and block codes.
Geocode Coordinates
Reverse geocode latitude/longitude coordinates to Census geographic areas. Takes decimal degree coordinates and returns associated Census geographies including states, counties, tracts, blocks, congressional districts, and other Census-defined geographic boundaries. Use this tool to identify what Census geographic areas a specific location falls within. Note: This uses the Census Geocoding Services API, which has a different base URL than the standard Census data API (uses geocoding.geo.census.gov).
Geocode Puerto Rico Address With Geography
Tool to geocode a Puerto Rico address and return coordinates plus Census geography data. Use for Puerto Rico addresses when you need geographic coordinates and Census identifiers like state, county, tract, and block codes. Supports urbanization names specific to Puerto Rico addressing.
