This growth coincides with the gradual diversification of the neighborhood. Despite income growth, the population decreased from 3,636 in 2013 to 2,793 in 2022, a 23.2% decline. The increasing median income alongside growing White and Hispanic populations suggests potential gentrification, with new, higher-income residents moving into the area.
