Whittier's demographic makeup with a Hispanic majority is consistent with trends in many parts of California, particularly in urban areas. The significant income growth over the past decade aligns with broader economic trends seen in many parts of the state.

Based on observed trends, Whittier is likely to maintain its "Hispanic Majority" status in the near future. The slow increase in diversity and rising incomes suggest a potential move towards a "Transitional Community" status. If current trends continue, a further slight decrease in the White population percentage, potential growth in Asian and multi-racial categories, and continued income growth may occur. These factors could eventually lead Whittier to transition into a "High Diversity" category, especially if the Hispanic majority begins to decrease and other racial groups increase their representation.

The economic prosperity could drive increased diversity by attracting a more varied workforce. However, demographic changes often occur slowly, and Whittier's strong Hispanic majority suggests that any major shifts would likely take place over an extended period, potentially beyond the next decade.
