The HNA is comprised of numerous data sources including the U.S. Census and the American Community Survey (ACS) which are all based on earlier (2019) findings. More recent, federal data was not available at the time this report was written. Although a Census was conducted in 2020, release of the data products has been delayed. You can read more about that here and here.
Also, bear in mind that the HNA data, in addition to the housing policy framework review and public engagement, are what guides the development of the HAP. The housing policy framework review evaluates current progress toward meeting the city’s housing element and the effectiveness of housing programs and policies. The public engagement process allows the community-at-large and key stakeholders to speak to the city’s more recent housing trends and needs.
