Why does the LSA report require I send three years worth to data?

While we encourage regions to maintain data back to the HUD lookback stop date of October 1, 2012 within HomelessData.com, the LSA report requires data for all actively enrolled clients from the period of 10/1/2015 to 9/30/2018, even though the reporting period itself is only 10/1/2017 to 9/30/2018. 

The rationale for this is that the LSA primarily reports on clients served within the reporting year, but the length of time measures include any day served or self-reported homeless in the 365-day period prior to the household's last active date in the reporting period, plus any additional days homeless associated with an enrollment or self-reported period that is continuous with the end of the 365-day period, as far back as the client’s record extends without a break to the lookback stop date.

The LSA also includes returns data about people who were served within the homeless system and exited during the year prior to the reporting period, and in the year prior to that.  There is also a “Three Year Data Quality” section within the LSA report.

Guidance on how to confirm that the data within the warehouse is comprehensive and covers the entire reporting period can be found in this FAQ.
