The median income in Carbondale has shown an upward trend, rising from $34,064 in 2013 to $41,979 in 2022, an increase of about 23%. This economic growth coincides with a decrease in population from 34,405 in 2013 to 29,350 in 2022. The inverse relationship between population decline and income growth may suggest a shift in the city's economic base or the departure of lower-income residents.

The trends in Carbondale reflect some broader national patterns. Many small to mid-sized cities have experienced population decreases, particularly those with significant student populations. The increase in median income, despite population decline, aligns with national trends of income growth in the post-2008 recession era.

Based on observed trends, Carbondale is likely to continue its gradual shift towards increased diversity. It may remain in the "Moderate Diversity" category for the near future, with potential to transition towards "High Diversity" if current trends continue. The slow but steady increase in Asian and Hispanic populations, combined with the stable Black population, suggests that the White majority may decrease below 60% in the coming years.

Economically, if the trend of population decrease and income increase continues, Carbondale might experience a shift in its socio-economic makeup. This could lead to gentrification in some areas, potentially altering the racial and economic landscape of certain neighborhoods.

These predictions are based on extrapolation of current trends. Unforeseen factors such as changes in university enrollment, economic policies, or migration patterns could significantly alter these projections. Continued monitoring of these demographic and economic indicators will be crucial for understanding Carbondale's evolving community dynamics.
