Each record in this file shows the totals for the entire ZCTA and place entity for the ZPOP, ZHU, ZAREA, ZAREALAND, PLPOP, PLHU, PLAREA, and PLAREALAND columns.  As only the intersections between the two entities are shown in the relationship file, the sum of the part columns for all records representing a specific ZCTA or place may not add up to the totals for the ZCTA or place.

As Places are not wall-to-wall entities and do not cover the entire nation, this file may not contain all ZCTAs.

2010 ZCTA to Metropolitan and Micropolitan Statistical Areas Relationship File Layout (zcta_cbsa_rel_10.txt)

This file shows the totals for the entire ZCTA and metropolitan/micropolitan statistical area (also known as core-based statistical area (CBSA)) for the ZPOP, ZHU, ZAREA, ZAREALAND, MPOP, MHU, MAREA, and MAREALAND columns.  As only the intersections between the two entities are shown in the relationship file, the sum of the part columns for all records representing a specific ZCTA or metropolitan/micropolitan statistical area may not add up to the totals for the ZCTA or metropolitan/micropolitan statistical area.

As metropolitan/micropolitan statistical areas are not wall-to-wall entities and do not cover the entire nation, this file may not contain all ZCTAs in the nation.

The metropolitan and micropolitan statistical codes appearing in the relationship file reflect the updates to metropolitan and micropolitan statistical areas as of December 2009, announced by the Office of Management and Budget on December 1, 2009, and in effect for the 2010 Census.
