The Pinehills neighborhood in Hattiesburg, Mississippi, has undergone a significant demographic transition from 2013 to 2022. As of 2022, the neighborhood is classified as a "Black Majority" community with 59% of the population identifying as Black. This represents a change from its earlier classification as a "White Majority" community in 2013 when 63% of the population identified as white. The shift in racial composition occurred over several stages, transitioning through periods of moderate diversity and majority-minority status before reaching its current demographic profile.

The neighborhood has experienced considerable fluctuations in both population and median income over the past decade. The median income in Pinehills has shown a general downward trend, correlating with the demographic shifts. When the neighborhood was "White Majority" in 2013-2014, median incomes were at their highest. As the community became more diverse, incomes fluctuated but generally decreased. With the transition to "Black Majority," median incomes have remained relatively low.

Population trends in Pinehills have been volatile, with significant increases in 2021 and 2022. The population nearly doubled from 782 in 2020 to 1,602 in 2022. This rapid growth coincides with the shift to a "Black Majority" and could indicate changing perceptions of the neighborhood or new development attracting residents.
