The trends observed in Highland Park align with patterns seen in many affluent suburbs across the United States. These areas often experience gradual increases in diversity, particularly among Hispanic and Asian populations, while maintaining a white majority.

Based on observed trends, Highland Park is likely to continue its gradual shift towards increased diversity. The white population may decrease to around 80% in the next 5-10 years. The Hispanic population could reach 12-13%. The Asian population and those identifying as two or more races may each approach 4-5%. These changes would represent increased diversity but would not be sufficient to reclassify Highland Park into a new category.

Economically, the increase in median income is likely to continue, maintaining Highland Park's status as an affluent community. This economic stability may continue to attract a diverse range of high-income residents, potentially accelerating the gradual diversification process.

Highland Park exemplifies a stable, affluent community experiencing slow but steady demographic changes. While it remains in the Low Diversity, White Majority category, the subtle shifts observed suggest a community in the early stages of a long-term transition towards greater diversity.
