# Census Bureau AI integration on Definable > The Census Bureau Data API provides developers with access to a wide range of statistical data collected by the U.S. ## What this connects 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. Vendor: https://www.census.gov/developers/ ## Tools available **81** tools available. First 12: - `CENSUS_BUREAU_GEOCODE_ADDRESS` — 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. - `CENSUS_BUREAU_GEOCODE_ADDRESS_GEOGRAPHIES` — 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. - `CENSUS_BUREAU_GEOCODE_ADDRESS_PARTS` — 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. - `CENSUS_BUREAU_GEOCODE_ADDRESS_WITH_GEOGRAPHY` — 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. - `CENSUS_BUREAU_GEOCODE_COORDINATES` — 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). - `CENSUS_BUREAU_GEOCODE_GEOGRAPHIES_ADDRESS_PR` — 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. - `CENSUS_BUREAU_GEOCODE_GEOGRAPHIES_BATCH` — Batch Geocode Addresses with Geographies — Batch geocode multiple addresses from a CSV file and return Census geography codes. Tool to geocode up to 10,000 addresses at once from a CSV file. Use when you need to convert addresses to geographic coordinates (latitude/longitude) and retrieve associated Census geography identifiers (state, county, tract, block FIPS codes). Input CSV format: Unique ID, Street address, City, State, ZIP Returns: Original data plus match status, coordinates, and geographic codes. - `CENSUS_BUREAU_GEOCODE_LOCATION_ADDRESS_PR` — Geocode Puerto Rico Address — Tool to geocode a Puerto Rico address with urbanization to latitude/longitude coordinates. Use when geocoding addresses in Puerto Rico that include urbanization or municipio components. - `CENSUS_BUREAU_GET_ACS1_YEAR_ESTIMATES` — Get ACS 1-Year Estimates — Tool to retrieve 1-year American Community Survey (ACS) estimates for a specified geography. Use when you need the most recent annual ACS data for a given area. - `CENSUS_BUREAU_GET_ACS5_YEAR_ESTIMATES` — Get ACS 5-Year Estimates — Retrieve 5-year American Community Survey (ACS) estimates from the U.S. Census Bureau. The ACS 5-year estimates provide reliable data for all geographic areas by combining 5 years of survey data. Use this tool to get population demographics, income statistics, housing characteristics, and other socioeconomic data at various geographic levels (nation, state, county, tract, place, metro area, etc.). Returns data as a list of rows where the first row contains column headers (variable names and geography identifiers) and subsequent rows contain the data values. - `CENSUS_BUREAU_GET_COMMUNITY_RESILIENCE_ESTIMATES` — Get Community Resilience Estimates — Retrieve U.S. Census Bureau Community Resilience Estimates (CRE) data. The CRE measures social vulnerability to disasters by estimating the number of individuals with risk factors (e.g., income, disability, housing) that may limit their capacity to absorb, recover from, and respond to the impacts of disasters. Key variables: - PRED0_E: Estimated persons with 0 risk factors (most resilient) - PRED12_E: Estimated persons with 1-2 risk factors - PRED3_E: Estimated persons with 3+ risk factors (most vulnerable) - POPUNI: Total population universe - Variables ending in _M are margins of error for the corresponding estimates Available for years 2019, 2021, 2022, 2023 at state and county levels. - `CENSUS_BUREAU_GET_COUNTY_BUSINESS_PATTERNS` — Get County Business Patterns — Tool to retrieve County Business Patterns (CBP) data for a specified year. Use when you need county-level business establishment and employment statistics filtered by industry and geography. ## Auth Auth schemes: `API_KEY`. ## How agents use Census Bureau Inside a Definable workflow, Census Bureau is one of the tools the **Distributor specialist** can call. Example coordination patterns: - **Researcher → Census Bureau** — the Researcher (GPT-5.5) pulls context from Census Bureau (records, threads, documents), synthesises findings, and briefs the rest of the team. - **Writer → Distributor → Census Bureau** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into Census Bureau (create record, post message, draft email). - **Designer / Engineer → Distributor → Census Bureau** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via Census Bureau (attach file, open PR comment, post status). The Verifier checks every Census Bureau call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention. ## Categories - analytics — https://definable.ai/apps/category/analytics/ - databases — https://definable.ai/apps/category/databases/ ## Related - HTML page: https://definable.ai/apps/census_bureau/ - Same category (analytics): https://definable.ai/apps/category/analytics/ - All integrations: https://definable.ai/apps/ - Workflow (multi-agent loop): https://definable.ai/workflow/ - Apps llms.txt index: https://definable.ai/llms-apps.txt
