Over the past decade, Peoria Heights has experienced a slight population decline, from 12,010 in 2013 to 11,060 in 2022. The median income has fluctuated, peaking at $63,101 in 2014 before decreasing to $56,185 in 2022. This trend may indicate an increasing need for affordable housing options.

The racial composition of the village has remained relatively stable. The white population has consistently represented the majority at approximately 84-86% of the total population. The Black population has decreased slightly from 9% in 2013 to 5% in 2022, while the Hispanic and Asian populations have shown small increases.

Despite these demographic changes, no new LIHTC projects have been developed in the last decade. This could be attributed to various factors, including limited funding availability or changes in local housing policies.

Peoria Heights has a single LIHTC-funded affordable housing project, Nuhill Properties, which has served the community since 1991. While this project provides 7 low-income units, it covers only a small fraction of the village's estimated housing inventory. The demographic trends over the past decade, including a slight population decline and fluctuating median income, suggest a potential ongoing need for affordable housing options in the village. However, the absence of new LIHTC projects in recent years indicates that other factors may be influencing affordable housing development in Peoria Heights.
