Throughout the analyzed period (2013-2022), Tybee Island has maintained a "Low Diversity" categorization. The white population has remained above 90% for the entire period, with minor fluctuations. The Black population increased slightly from 2% in 2014 to 3% in 2022. The percentage of individuals identifying as two or more races grew from 1% in 2014 to 3% in 2022. These changes suggest a gradual trend towards slightly increased diversity, though not enough to shift the overall categorization of the community.
The median income in Tybee Island has shown significant growth and volatility over the past decade. From 2013 to 2022, the median income increased from $70,200 to $89,624, representing a 27.7% growth. There was a notable spike in 2021, with median income reaching $113,228, before dropping back in 2022. This upward trend in median income correlates with the subtle increases in diversity, suggesting that the area may be attracting a more diverse, affluent population.
Population trends have remained relatively stable, with minor fluctuations between 2,700 and 3,000 residents throughout the period. This stability suggests that any demographic changes are likely due to gradual replacement of existing residents rather than significant influxes of new populations.
Tybee Island's "Low Diversity" categorization contrasts with national trends towards increasing diversity in many urban and suburban areas. The significant income growth observed in Tybee Island outpaces national averages for the same period, indicating a particularly prosperous local economy or an influx of higher-income residents. The stability in population numbers, despite rising incomes, suggests that Tybee Island may have limited housing stock or zoning restrictions that prevent significant population growth, which is common in desirable coastal communities.
While Tybee Island remains a predominantly white, affluent community with low diversity, there are subtle signs of demographic change. The economic prosperity of the area, as evidenced by rising median incomes, may be a factor in attracting a slightly more diverse population. However, these changes are gradual and have not yet significantly altered the overall demographic makeup of the community. The area's desirability as a coastal location likely contributes to its economic strength and stable population, potentially limiting more rapid demographic shifts.
