Over the past decade, Belage has experienced notable demographic changes. In 2013, the neighborhood was categorized as "White Majority" with 52% of the population. By 2022, it transitioned to a "Moderate Diversity" classification. This shift is attributed to a decrease in the White population percentage and an increase in other racial groups, particularly Asian and Hispanic populations. The Asian population has remained relatively stable, fluctuating between 22% and 32% over the years. The Hispanic population has shown a gradual increase from 12% in 2013 to 14% in 2022. The Black population, while small, has increased from 6% in 2013 to 8% in 2022.

The median income in Belage has shown an upward trend. From $188,988 in 2013, it rose to $200,000 by 2019 and has remained at that level through 2022. This consistent high income level correlates with the increasing diversity, suggesting that the neighborhood has attracted affluent individuals from various racial backgrounds. As the median income increased, the population decreased from 48 in 2013 to 36 in 2022. This could indicate a trend towards larger, more expensive homes replacing smaller residences, potentially pricing out some former residents and attracting wealthier newcomers.
