FIPS Support was withdrawn for the following entities (with former FIPS series): • States & equivalent entities (FIPS 5-2) • Counties & equivalent entities (FIPS 6-4) • Congressional Districts (FIPS 9-1) • Metropolitan/Micropolitan Statistical Areas & related statistical areas (FIPS 8-6) • Places & county subdivisions (55-3)
FIPS to ANSI Transition Code standards with oversight changes only: • States and equivalent entities • FIPS 5-2 • ANSI: INCITS 38:2009
FIPS to ANSI Transition Code standards with oversight changes only: • Counties and equivalent entities • FIPS 6-4 • ANSI: INCITS 31:2009
FIPS to ANSI Transition Code standards with oversight changes only: • Congressional Districts • FIPS 9-1 • ANSI: INCITS 455:2009
Metropolitan and micropolitan statistical areas and related statistical entities Code structure adopted in 2003 was not under FIPS oversight Geographic EntityLengthRange Metropolitan Statistical Areas 5 digits 10000-59999 Micropolitan Statistical Areas 5 digits 10000-59999 Metropolitan Divisions 5 digits 10004-59994* New England City and Town Areas 5 digits 70000-79999 NECTA Divisions 5 digits 70004-79994* Combined Statistical Areas 3 digits 100-599 Combined NECTAs 3 digits 700-799 *Metropolitan divisions and NECTA divisions are distinguished from metropolitan and micropolitan statistical areas and NECTAs by codes that end in “4.” Now ANSI INCITS 454:2009
Place and County Subdivisions • US Geological Survey was the maintenance agency for FIPS 55-3. • Adopted Geographic Names Information System (GNIS) ID as standard code, effective January 1, 2006 • GNIS ID is a variable length, permanent, numeric identifier, up to 10 digits (though none are longer than 8 digits)
FIPS v. ANSI for Places FIPS GNIS GNIS (civil) (populated place) Alexandria, VA 01000 1498415 1492456 Baltimore, MD 04000 1702381 597040 Seattle, WA 63000 2411856 1512650 Tacoma, WA 70000 2412025 1512713 Takoma Park, MD 76650 2390660 598146 Washington, DC 50000 1702382 531871
IMPORTANT NOTE: Use the ID number for “CIVIL” under the feature class to match to Census data when using the ANSI code
What will the Census Bureau do? GNIS IDs will be included in the MAF/TIGER database for the following entities: • States and equivalent areas* • Counties and equivalent areas* • County subdivisions • Sub-minor civil divisions (Puerto Rico only) Consolidated cities • Incorporated places and census designated places • American Indian/Alaska Native/Native Hawaiian areas • Alaska Native Regional Corporations • American Indian tribal subdivisions *Supplemental codes only; the GNIS ID does not supplant the standard 2-digit state code and 3-digit county code.
What will the Census Bureau do? • Commitment to maintain and issue new 5-digit place and county subdivision codes through at least 2012 • Because “FIPS” is a well-known and recognized acronym, we will retain it as “Federal Information Processing Series”
What will the Census Bureau do? We will include the GNIS ID (as fixed length character data) in products containing geographic information, along with the 5-digit place and county subdivision codes.
