"This report is the second part of a two-part series. The first part is called The 2013 Point-in-Time Estimates of Homelessness: Part 1 of the 2013 Annual Homeless Assessment Report (AHAR) to Congress and was published in November 2013. The Part 1 report provides estimates of homelessness based on the Point-in-Time (PIT) count data gathered by communities throughout the country on a single night in January. The estimates are provided at the national-, state-, and CoC-levels. New to the 2013 AHAR is information on unaccompanied homeless children and youth and chronically homeless people in families.

Part 2 of the 2013 AHAR builds on the Part 1 report by adding 1-year estimates of sheltered homelessness based on data from Homeless Management Information Systems (HMIS). The HMIS estimates provide detailed demographic information about people who use the nation’s shelters during a 12-month period."
