Over the last decade, Arlington Heights has experienced population fluctuations, with the most recent data showing a population of 74,207 in 2022. The median income has increased from $79,940 in 2013 to $113,970 in 2022, potentially indicating a growing need for affordable housing options for lower-income residents.

The racial distribution data from 2022 shows that the city is predominantly white (73%), with Asian (10%), Hispanic (9%), and Black (5%) populations also represented. The introduction of LIHTC-funded housing in 2019 may reflect efforts to maintain diversity and inclusivity in the community as income levels rise.

Arlington Heights has a small but recent LIHTC-funded affordable housing presence, with one project providing 18 low-income units. This represents a small percentage of the city's estimated housing stock but marks the beginning of LIHTC involvement in the community. The rising median income over the past decade suggests a potential increasing need for affordable housing options. The city's racial diversity, coupled with its growing economy, may continue to influence future affordable housing initiatives.
