The median income in Deweyville has shown an overall upward trend, rising from $74,130 in 2013 to $78,229 in 2022. This represents a 5.5% increase over the decade, slightly outpacing inflation. As the community has become slightly more diverse, the median income has generally increased, suggesting that the incoming populations may be contributing to economic growth.

The stability of the white majority alongside rising incomes may indicate that the area is attractive to middle to upper-middle-class families from various backgrounds. The population has decreased from 23,317 in 2013 to 20,840 in 2022, a 10.6% decline. This could suggest that while the area is becoming more affluent, it may be experiencing some outmigration, possibly due to rising costs of living or changing job markets.

The demographic shifts in Deweyville, though slow, align with broader national trends of increasing diversity in suburban and rural areas. The income growth in the area appears to be moderate and stable. The population decline contrasts with the growth seen in many Texas suburbs, suggesting that Deweyville may be facing unique local challenges or may be part of a broader rural population decline trend.

Deweyville remains a "Low Diversity" community with a strong "White Majority," but there are signs of a gradual transition towards greater diversity. This shift is occurring alongside moderate economic growth, as evidenced by rising median incomes. The declining population raises questions about the long-term sustainability of these trends and the overall attractiveness of the area to new residents. The community appears to be in the early stages of a demographic transition.
