Willow Grove has experienced demographic changes over the past decade. The population has remained relatively stable, increasing slightly from 17,517 in 2014 to 18,255 in 2022. Median income has grown significantly, rising from $79,095 in 2014 to $90,780 in 2022, indicating an improvement in residents' economic conditions.

The racial distribution in Willow Grove has shown a gradual decrease in the white population, from 82% in 2014 to 76% in 2022. There has been a modest increase in diversity, with growth in the Hispanic population (from 3% to 6%) and the two or more races category (from 3% to 5%). The black population has remained stable at approximately 8%, while the Asian population has fluctuated between 4% and 5%.

The completion of the Crest Manor project in 2016 coincides with a period of relative demographic stability in Willow Grove. The project may have been developed to address the needs of the growing diverse population and to provide affordable housing options in an area experiencing rising median incomes.

Willow Grove's LIHTC-funded affordable housing inventory, though limited to one project, provides 46 low-income units across various unit sizes. The project represents a small but significant portion of the city's housing stock, contributing to the diversity of housing options available to residents. The demographic trends over the past decade, including population stability, increasing median income, and growing diversity, suggest an evolving community that may benefit from continued investment in affordable housing to ensure equitable access to housing for all residents.
