Need code list for AIA.
The SF1 identification section shows this field -- American Indian Area/Alaska Native Area/
Hawaiian Home Land (FIPS) AIANHHFP 5 81 A/N
00001–89999 American Indian area, Alaska Native area, or Hawaiian home land
This is apparently the code field required by the API (both SF1 and ACS). Geography division cannot locate this file. most all references are now 4 digit ANSI codes (includiing shapefiles).
Hoping you can help with code list or revised API structure.
