`census_area`

Pack: fcc · Endpoint: https://gateway.pipeworx.io/fcc/mcp

Resolve a US latitude/longitude (decimal degrees) to its full Census area record: block/county/state FIPS + names plus 2020 block population and FCC market-area codes (BEA, BTA, CMA, EAG, MEA, MTA, PEA, REA, RPC, VPC). Richer than census_block; use when you need population or FCC licensing market codes for a point.

Parameters

Name	Type	Required	Description
`lat`	number	yes	Latitude in decimal degrees (e.g. 38.8976).
`lon`	number	yes	Longitude in decimal degrees (e.g. -77.0365).
`censusYear`	string	no	Census vintage: “2020” (default) or “2010”.
