The median income in the neighborhood has fluctuated over the years. It was $36,703 in 2013, peaked at $44,594 in 2021, and dropped to $34,565 in 2022. These income fluctuations do not appear to directly correlate with the demographic shifts.

The population has remained relatively stable, ranging from 2,000 to 2,200 residents throughout the decade. This stability in population size, despite racial composition changes, indicates that demographic shifts are likely due to population turnover rather than significant influxes or exoduses.

The increasing Black population percentage in Longleaf Heights-Avenues aligns with patterns seen in many urban areas across the Southern United States. This phenomenon has been observed as African Americans move from Northern cities back to the South over recent decades.

The increasing diversity, particularly in Hispanic and multiracial populations, reflects national trends of increasing diversity in American communities. However, the relatively low percentage of these groups compared to national averages suggests that Hattiesburg may be in the early stages of this diversification process.

The economic fluctuations in the neighborhood, particularly the recent decline in median income, may reflect broader economic challenges faced by many mid-sized cities in the post-2008 recession era and exacerbated by the COVID-19 pandemic.

Longleaf Heights-Avenues presents a neighborhood in transition, moving from a diverse community to one with a stronger Black Majority. While economic indicators have fluctuated, the community has maintained a stable population size, suggesting resilience in the face of demographic and economic changes.
