PERSONS is a 4-digit numeric variable.

Description

PERSONS indicates how many person records are included in the household (i.e., the number of person records associated with the household record in the sample). These person records will all have the same serial number (SERIAL) as the household record. The information contained in the household record will normally apply to all of these persons.

Comparability — General

This variable is fully comparable across all samples.

Note that some samples include vacant households: ones with zero persons. If a data extract is created in rectangular format (the default for the system), vacant households will not be included. The following samples contain vacant households:

Note also that some samples are random samples of individuals, not households. In IPUMS data format, all "households" in such samples have one person. The individual-level samples are identified in the extract system; they are Canada 1971, 1981, 1991, 2001, Chile 1960, Colombia 1964, Costa Rica 1963, Dominican Republic 1960, 1970 Ecuador 1962, Finland 2010, Germany 1970, Kenya 1979, Liberia 1974, Mexico 1960, Netherlands 1960, 1971, 2001, 2011, Pakistan 1981, Slovak Republic 1991, 2001, 2011, Suriname 2004, United Kingdom 2001, and Spain 1981.
