Calculations

  1. For the Racial Equity visualizations, we were previously grouping all the Middle Eastern or North African (MENA) data collected in HDIS with the 'white' category to avoid comparing less than a year of data collected with the MENA category with a full year of ACS data. With a full year of MENA data starting in this release, MENA and White categories are un-grouped on the racial equity visualizations for calendar year 2024.

Calculations

  1. Age is now calculated in accordance with FY 2024 HMIS Standard Reporting Glossarylogic (see page 17). Previously, age was calculated solely based on Date of Birth and project start date. It now accurately reflects the report start date as well. Any visualization that includes age may have different values compared to previous releases.
  2. Household Type is now calculated in accordance with the FY2024 HMIS Standard Reporting Glossary. Previously, the most recent enrollment was used to determine household type, rather than the logic suggested on page 21 of the Standard Reporting Glossary which uses all active enrollments during a report period and has tie–breaking logic. See the section on page 21 that starts with “The Following Logic should be applied in order:” Any visualization that includes household type may have different values compared to previous releases.
