The median income in zip code 22448 has remained relatively stable over the decade, fluctuating between $57,505 (2014) and $70,170 (2021), with the most recent figure being $63,707 in 2022. This suggests a slight economic improvement over the decade, though not a dramatic one. Notably, the transition to a clearer White majority did not correspond with a significant increase in median income.

The population of the zip code has decreased dramatically from 1,623 in 2010 to 718 in 2022, a reduction of more than 55%. This significant population decline could be a major factor in the changing racial demographics, possibly indicating that certain racial groups were more likely to leave the area than others.

While national trends have shown increasing diversity in many areas, this zip code has moved in the opposite direction, becoming less diverse over time. The stability in median income, despite significant demographic changes, contrasts with some national patterns where changes in racial composition often correlate with economic shifts. The substantial population decrease in this zip code is noteworthy and may be indicative of broader regional trends, such as rural-to-urban migration or changes in local industries.

In conclusion, zip code 22448 in Dahlgren Center, Virginia, has undergone a significant demographic transformation over the past decade, moving from a moderately diverse community to one with a clear White majority. Despite these racial shifts, the economic indicators have remained relatively stable, suggesting that factors beyond income have been driving these changes. The dramatic population decrease and the growing multiracial population indicate that this area is in a state of significant transition, the full impacts of which may not be fully realized for years to come.
