Over the past decade, Marina Bay has undergone a transition from "Moderate Diversity" to "High Diversity." In 2013, the neighborhood could be categorized as having "Moderate Diversity" with White (32%), Black (29%), and Hispanic (24%) populations being the most prominent. The Asian population was 12%. By 2022, the community had evolved into a "High Diversity" area. Notable changes include an increase in the Asian population from 12% to 19%, a decrease in the Black population from 29% to 22%, a slight increase in the White population from 32% to 34%, a decrease in the Hispanic population from 24% to 16%, and an increase in the two or more races category from 1% to 8%.

The demographic shifts correlate with changes in median income. In 2013, the median income was $79,014. By 2022, it had increased to $97,022, a 22.8% rise. This increase coincides with the growing Asian population and slight increase in the White population, potentially indicating an influx of higher-income residents. The decrease in Black and Hispanic populations might suggest some displacement of lower-income residents or changing neighborhood preferences. The population has grown from 3,699 in 2013 to 4,454 in 2022, a 20.4% increase. This population growth, coupled with rising incomes, suggests that Marina Bay has become an increasingly desirable neighborhood.
