Over the past decade, Black Hammock Island has undergone a gradual transition from a homogeneous community to one showing early signs of diversification. In 2013, the neighborhood was classified as Low Diversity with a 99% white population. By 2022, while still maintaining a White Majority status, the community has seen a modest increase in diversity. The white population decreased from 99% in 2013 to 82% in 2022. Hispanic representation increased from 1% to 7%. Asian population grew from 0% to 4%. The category of two or more races expanded from 0% to 6%. This shift suggests that Black Hammock Island is in the early stages of becoming a Transitional Community, moving slowly away from Low Diversity towards Moderate Diversity.

The demographic changes have coincided with economic growth. Median income rose from $65,923 in 2013 to $85,938 in 2022, a 30% increase. The population fluctuated but showed overall growth from 1,903 in 2013 to 2,312 in 2022. The rising income levels may have attracted a more diverse population, potentially explaining the gradual increase in minority representation. Conversely, the influx of new residents from various backgrounds could have contributed to economic growth through increased business activity and property values.
