Revisions & Notes

On rare occasions, the Point-in-Time estimates published in prior editions of the AHAR have been subsequently updated. The estimates described in this file represent the latest versions of these data (as of the publication of this file). The revisions are summarized below:

  1. Beginning in the 2014 AHAR Part 1, the PIT estimates of unsheltered people experiencing homelessness in the Los Angeles City and County CoC, CA-600, were updated for the years 2007–2013. Within the CoC, the adjustments subtracted: 20,746 total people from 2007 and 2008; 9,451 total people in 2009 and 2010; 10,800 total people in 2011 and 2012; and 18,274 total people from 2013. These adjustments also caused drops in the key unsheltered populations reported on the AHAR, individuals, people in families, veterans, and chronically homeless individuals. More details on the size of each adjustment, by population, can be found in the 2014 AHAR Part 1.

  2. Beginning in the 2014 AHAR Part 1, the PIT estimate of veterans experiencing homelessness in shelter projects in the Phoenix/Mesa/Maricopa County Regional CoC, AZ-502, was updated for the year 2013, increasing by 214 veterans. This update did not change the total number of people experiencing homelessness in shelter projects (or overall) in the CoC—just the number of those people who were classified as veterans.

  3. Beginning in the 2015 AHAR Part 1, the PIT estimates of unsheltered people experiencing homelessness in the Las Vegas/Clark County CoC, NV-500, were updated for the years 2007–2014. Within the CoC, the adjustments subtracted: 3,884 total people from 2007 and 2008; 3,389 total people in 2009 and 2010; 1,429 total people in 2011 and 2012; 1,404 total people from 2013; and 1,974 total people from 2014. These adjustments also caused drops in the key unsheltered populations reported on the AHAR, individuals, people in families, veterans, and chronically homeless individuals. More details on the size of each adjustment, by population, can be found in the 2015 AHAR Part 1.

  4. Beginning in the 2015 AHAR Part 1, the PIT estimates of veterans experiencing homelessness in the Anchorage CoC, AK-500, were updated for the year 2014. The sheltered estimate for this CoC increased by 71 veterans, and the unsheltered estimate increased by 18 veterans. Neither of these updates changed the total number of people experiencing homelessness in the CoC—just the number of those people who were classified as veterans.

  5. Beginning in the 2017 AHAR Part 2 and the 2018 AHAR Part 1, the PIT estimates of unsheltered people experiencing homelessness in the Los Angeles City and County CoC, CA-600, were updated for the year 2017, decreasing by a total of 2,746 people. The adjustment also caused drops in the key unsheltered populations reported on the AHAR, individuals, people in families, veterans, and chronically homeless individuals. More details on the size of each adjustment, by population, can be found in the 2017 AHAR Part 2 and the 2018 AHAR Part 1.

  6. Beginning in the 2019 AHAR Part 1, the PIT estimates describing people experiencing homelessness in 2018 in Danbury, Connecticut, were shifted between two Connecticut CoCs to reflect a change in the jurisdictions they serve; 123 people experiencing homelessness in Danbury and originally reported in CT-505’s 2018 PIT count were moved to CT-503. This shift did not change the national estimates or state estimates, as it simply moved people from one Connecticut CoC to another.

  7. State “MP” N/As 2015, 2016; State “AS” N/As 2015-2020. Therefore, removed those 2 states for the trend data.

  8. Reason for manual-input of MI and SUD variables

As explained by HUD:

“Unfortunately, HUD decided not to release the data (Severely Mentally Ill & Chronic Substance Abuse) in excel or csv format. The data are included in the PDF files because CoCs reported on those data elements, but HUD has the disclaimer on each report because the data quality is unreliable. Data collection and reporting were inconsistent, and there were methodology changes. Note that each report states: ‘HUD has conducted a limited data quality review but has not independently verified all of the information submitted by each CoC. The reader is therefore cautioned that since compliance with these standards may vary, the reliability and consistency of the homeless counts may also vary among CoCs. Additionally, a shift in the methodology a CoC uses to count the homeless may cause a change in homeless counts between reporting periods.’”
