The population has remained relatively stable, fluctuating between 71,825 and 77,259 over the decade. This stability, combined with rising incomes, may indicate a community that is becoming more established and potentially more exclusive.

The income growth in Arlington Heights likely outpaces national averages, potentially reflecting broader trends of income inequality and concentration of wealth in suburban areas.

Based on the observed trends, Arlington Heights is likely to maintain its "Low Diversity" status in the near future. However, there are indications that it may be slowly transitioning towards a "Moderate Diversity" category. The presence of significant Asian and Hispanic populations suggests a gradual diversification process.

Economically, the upward trend in median income is likely to continue, potentially attracting more diverse, high-income professionals. This could lead to a scenario where Arlington Heights becomes a "Transitional Community" in the coming years, with increasing representation from Asian and Hispanic populations, particularly in higher income brackets.

The community might evolve into a "Moderate Diversity" category over the next decade if current trends accelerate, with the white population potentially dropping below 70% and Asian and Hispanic populations each growing to around 15%. This transition would likely be accompanied by continued increases in median income, potentially reshaping the socio-economic landscape of Arlington Heights.

Arlington Heights currently maintains a relatively homogeneous racial composition, however economic factors and subtle demographic shifts suggest a potential for increased diversity in the future, albeit at a gradual pace. The community's evolving character will likely be shaped by the interplay between its growing affluence and its slowly diversifying population.
