The median income in Green Isle has shown an upward trend over the past decade. In 2013, the median income was $66,511. By 2021, it had risen to $85,123, an increase of about 28% over eight years. There was a slight decrease to $79,534 in 2022, but this still represents a significant increase from 2013 levels.

Population trends show a gradual increase from 807 in 2010 to 897 in 2019, followed by a decrease to 843 in 2020, and then a slight recovery to 868 in 2022. These population changes have been relatively minor and have not significantly altered the racial makeup of the community.

Green Isle's demographic stability contrasts with national trends towards increasing diversity in many areas of the United States. The city's consistently high percentage of white residents and low representation of other racial groups suggests that it has not experienced the demographic shifts seen in many other parts of the country.

The economic growth in Green Isle, as evidenced by the rising median income, aligns with broader trends of economic recovery and growth following the 2008 financial crisis. However, the lack of corresponding increase in racial diversity is noteworthy and may indicate factors such as limited job market diversity, housing patterns, or community preferences that have maintained the existing demographic structure.

Green Isle presents a picture of a stable, predominantly white community that has experienced economic growth without significant changes in its racial composition over the past decade. While there are hints of very slight increases in diversity, the overall characterization remains one of "Low Diversity" with strong economic indicators.
