This economic growth correlates with the slight increase in diversity, suggesting that the area may be attracting a more diverse population as it becomes more prosperous. However, the relationship between economic growth and diversity remains limited, given the area's persistent low diversity.

Population trends show steady but modest growth, from 5,015 in 2013 to 5,239 in 2022, an increase of about 4.5%. This slow population growth, combined with rising incomes, suggests a stable, affluent community that is changing gradually.

The area's low diversity contrasts with national trends towards increasing racial and ethnic diversity in many parts of the United States. The median income of $85,113 in 2022 is significantly higher than the national median household income, which was around $70,784 in 2021. The slow pace of diversification in this zip code suggests it may be lagging behind national trends in urban and suburban areas, which have generally seen faster increases in diversity over the past decade.

The zip code 53508 in Belleville, Wisconsin, remains a predominantly white, affluent area with low diversity. There are subtle signs of slow demographic changes. The community's economic prosperity has increased over the decade, which may eventually lead to more significant demographic shifts in the future if current trends continue. However, any transition towards greater diversity is occurring at a much slower pace than in many other parts of the country.
