The median household income in Gretna has increased from $93,873 in 2013 to $118,925 in 2022, with a peak of $133,437 in 2021. This represents an increase of about 26.7% over nine years, outpacing inflation and indicating strong economic growth in the area.

The population has grown from 11,398 in 2013 to 17,938 in 2022, representing a growth of about 57.4%. This rapid population growth, combined with rising incomes, suggests that Gretna has become an increasingly desirable place to live, likely attracting affluent residents.

The correlation between the minor increase in diversity and the significant rise in median income suggests that the area may be attracting a small number of diverse, high-income professionals. However, the persistent "Low Diversity" status indicates that this diversification is happening at a very slow pace.

Gretna's demographic profile is relatively unusual in the context of broader national trends. Many suburban areas across the United States have been experiencing more rapid diversification over the past decade. Gretna's persistent "Low Diversity" status, combined with its high median income and rapid population growth, suggests it may be a particularly desirable enclave for affluent white residents.

The substantial income growth in Gretna outpaces national averages, which have seen more modest gains in median household income over the same period. This indicates that Gretna is becoming increasingly affluent relative to national norms, potentially creating a more exclusive community.

While Gretna (zip code 68028) has experienced significant economic growth and population increase over the past decade, its racial demographics have remained relatively stable, maintaining its status as a "Low Diversity" community with a strong "White Majority." The minor increases in diversity, particularly in the Hispanic population, suggest the potential for future changes, but these shifts are occurring at a much slower pace than the area's economic growth.
