Census Block Scraper
Resolves US coordinates to their Census block FIPS code, county, state and 2020 block population via the FCC Area API. No login, no proxy, no browser.
Input
| Field | Type | Notes |
|---|---|---|
locations | array | Required. "latitude,longitude" strings. Default: US Capitol, Empire State Building, Golden Gate Bridge. |
censusYear | string | 2020 | 2010 | 2000. Default 2020. |
Output
One row per coordinate: latitude, longitude, censusYear, blockFips,
stateFips, countyFipsPart, tractCode, blockCode, countyFips,
countyName, stateCode, stateName, blockPopulation, boundingBox.
Notes
- FIPS codes are strings, not numbers. California's state FIPS is
06; the moment it becomes a number it turns into6and stops joining against any other Census dataset. Everything here stays a string. - The 15-digit block code is also split into its parts — state, county, tract, block — because most Census joins key on the tract or county prefix rather than the whole block.
- A coordinate on a boundary can return more than one result, so every result is emitted rather than only the first.
block_pop_2020is only populated for the 2020 geography; earlier Census years return the block without a population and the field stays null.- Coordinates outside US coverage come back with an empty
resultsarray and HTTP 200, so they are logged and skipped, not treated as errors.
