This document describes the Public Use File (PUF) created from data collected during monthly MHS. This document provides a brief description of the MHS and the differences between the MHS data and the records available in the PUF. This document also explains how to determine unit-level characteristics from the PUF and how to create estimates and measures of sampling variability from the PUF data. The PUF allows data users greater access to these data than standard tabulations and provides data users the ability to create a wider variety of tables tailored specifically to their data needs.
