The Public Use Microdata Sample (PUMS) file contains records representing a 10-percent sample of the  occupied and vacant housing units in Guam and the people in the occupied units. People living in group  quarters also are included in the sample. The file contains a weight of 10 for each person and housing  unit, which when applied to the individual records, expands the samples to the relevant total. See  Chapter 6, Data Dictionary, for a complete list of the variables in this file.
