Longitudinal System Analysis (LSA)

A critical aspect of the McKinney-Vento Homeless Assistance Act, as amended, is a focus on viewing the local homeless response as a coordinated system of homeless assistance options as opposed to homeless assistance programs and funding sources that operate independently in a community.

The Longitudinal Systems Analysis (LSA) report, produced from a CoC’s Homelessness Management Information System (HMIS) and submitted annually to HUD via the HDX 2.0, provides HUD and Continuums of Care (CoCs) with critical information about how people experiencing homelessness use their system of care. This page provides guidance for CoCs about how to use and interpret their LSAs as well as for HMIS software providers about how to program the report.
