Description

Definition
MIGPUMA1 indicates the person's Migration PUMA of residence 1 year ago within the United States.

A Migration PUMA may correspond to either one or multiple PUMAs, so the codes and extents for PUMAs of residence 1 year ago (in MIGPUMA1) and the PUMA (in GEO2_US) of current residence will differ.

Codes in Multi-Year Samples: In Multi-Year ACS files, the meaning of PUMA codes depends on the year the respondent was interviewed. Codes for 2011 and earlier responses are based on 2000 PUMA definitions, and codes for 2012 and later responses are based on 2010 definitions.

See the Geography and GIS page of IPUMS USA for greater details on Migration PUMA definitions, maps, and relationships to PUMAs
