The median income in Mount Vernon has shown fluctuations over the past decade. It rose from $77,054 in 2013 to a peak of $90,639 in 2021. There was a decrease to $75,782 in 2022. Despite these fluctuations, the overall trend shows an increase in median income from 2013 to 2022, even with the recent decrease. This suggests a generally prosperous community that has maintained its economic status while experiencing minor demographic shifts.

The population has remained relatively stable, growing from 6,670 in 2013 to 6,776 in 2022, a modest increase of about 1.6% over a decade. This stability in population, combined with the maintained racial composition and overall increase in median income, indicates a community that has experienced economic growth without significant demographic change.

Mount Vernon's demographics stand in contrast to national trends towards increasing diversity. Many U.S. cities have been experiencing a shift towards "Moderate Diversity" or "High Diversity" over the past decade. Mount Vernon's stability as a predominantly white community with increasing affluence suggests it may be somewhat insulated from broader demographic shifts occurring in more urban or diverse areas of the country.

The recent drop in median income from 2021 to 2022 could be reflective of broader economic challenges faced nationwide, such as inflation and economic uncertainty following the COVID-19 pandemic. However, the overall increase in median income over the decade indicates that Mount Vernon has generally maintained its economic standing, even as it has resisted significant demographic change.

Mount Vernon presents a picture of a stable, affluent, predominantly white community that has experienced minor increases in diversity and overall economic growth over the past decade, while maintaining its core demographic character. The community appears to be slowly trending towards slightly increased diversity, but at a pace much slower than many other areas of the country.
