Over the past decade, Annville's population has remained relatively stable, with slight fluctuations. The median income has shown an overall increasing trend, rising from $61,626 in 2019 to $67,798 in 2022. This increase in median income might indicate a reduced need for additional affordable housing in recent years.

The racial composition of Annville has remained predominantly white, though there has been a slight decrease in the white population from 90% in 2019 to 86% in 2022. Concurrently, there has been a small increase in the Hispanic population from 6% to 8%, and in the Black population from 2% to 4% during the same period.

Annville's LIHTC-funded affordable housing inventory consists of a single project completed in 1999, providing 22 one-bedroom units targeted towards the elderly population. While this project covers only a small percentage of the city's estimated housing stock, it has been a consistent source of affordable housing for over two decades. The city's relatively stable population and increasing median income in recent years may explain the lack of additional LIHTC projects. However, the slight changes in racial demographics could potentially influence future affordable housing needs in the community.
