The median income in McDonough demonstrated an overall upward trend, rising from $62,373 in 2013 to $72,733 in 2022. This growth was not linear. A significant increase in median income occurred between 2019 ($68,598) and 2021 ($78,483), followed by a decrease in 2022. This fluctuation coincides with the rapid population growth and shifting racial demographics, suggesting a complex relationship between economic and demographic factors.

The trends observed in McDonough align with broader patterns seen in many suburban areas near major metropolitan centers. The increase in racial diversity, particularly the growth of the Black population, is consistent with trends of suburbanization among minority communities observed in many parts of the United States.

Based on the observed trends, McDonough is likely to continue its status as a "Racial Majority" city with a predominant Black population. The consistent growth in the "Two or More Races" category suggests that the city may eventually transition towards a "Majority-Minority" status, where no single racial group constitutes a majority, but minority groups collectively form the majority.

Economically, if McDonough continues to attract new residents and maintain its growth trajectory, it may experience further increases in median income. However, the recent decrease in 2022 suggests potential volatility, possibly due to broader economic factors or local changes.

McDonough appears to be a dynamic, evolving community experiencing significant demographic shifts alongside economic development. The city's future will likely be characterized by increasing diversity within its Black majority context, potentially leading to new social and economic dynamics that will shape its development in the coming years.
