The median income in the area has shown an upward trend, particularly from 2019 onwards. It increased from $58,507 in 2019 to $71,216 in 2020, a 22% increase. This economic improvement coincides with a slight increase in the white population percentage and a decrease in the Black population percentage from 2021 to 2022.

The population has fluctuated over the years, decreasing from 4,182 in 2010 to 3,797 in 2016, before increasing to 4,112 in 2022. This population recovery aligns with the period of income growth, suggesting improved economic opportunities may have influenced population changes.

The economic growth in this zip code appears to exceed national trends, particularly considering the challenges posed by the COVID-19 pandemic in 2020. The persistence of a "White Majority" in this Georgia zip code contrasts with broader national trends towards increasing diversity in many urban and suburban areas.

The brief shift towards greater diversity in 2021, followed by a return to a stronger white majority in 2022, could indicate underlying socio-economic or policy changes affecting demographic composition. The disappearance of the Hispanic population by 2022 is noteworthy and unusual compared to national trends.

In conclusion, zip code 30220 maintains a "White Majority" status with "Low Diversity" and has experienced significant economic growth. The community has shown fluctuations in racial composition, particularly in the Black and Hispanic populations, which may be related to the area's economic changes. These trends suggest a dynamic local environment that, while not following broader national diversity trends, is experiencing economic improvements.
