Monessen has experienced a declining population trend over the past decade, decreasing from 7,583 in 2015 to 6,876 in 2022. Despite this population decrease, the median income has shown a general upward trend, rising from $36,895 in 2015 to $48,049 in 2022.

The racial composition of Monessen has remained relatively stable. The white population decreased slightly from 82% in 2015 to 74% in 2022, while the Black population increased from 12% in 2015 to 16% in 2022. The Hispanic population has consistently remained low at approximately 2%.

The absence of new LIHTC projects in the last decade may be attributed to the declining population and increasing median income, potentially reducing the perceived need for additional low-income housing units.

Monessen's LIHTC-funded affordable housing inventory provides 13 low-income units to the community. The program has contributed an average of $17,694 per unit in federal funding. The city's affordable housing stock primarily consists of one-bedroom units, potentially serving smaller households or individuals. Despite the lack of new LIHTC projects in recent years, Monessen has experienced population decline and income growth, which may have influenced affordable housing development decisions. The racial composition has remained relatively stable with slight shifts towards increased diversity.
