Get the SUMLEVEL code (e.g. "040", "150") from a fipstype string (e.g. "state", "blockgroup")

SUMLEVEL strings extracted from a Census GEO_ID are always 3 characters (e.g. "020", "040", "150"), so this function returns 3-character strings to match that width.

Usage

sumlevel_from_fipstype(ftype)

Arguments

ftype

character vector of fipstype strings; case-insensitive

Value

character vector of 3-character SUMLEVEL codes, NA for unsupported
