This substantial income growth coincided with a population increase from 65,033 in 2019 to 71,669 in 2022, potentially indicating economic development and job growth in the area. The high Hispanic population in Harlingen aligns with broader demographic trends in Texas, particularly in regions near the U.S.-Mexico border. The recent rapid income growth exceeds national averages, suggesting localized economic improvements or changes in the job market.

Based on observed trends, Harlingen is likely to maintain its status as a Hispanic Majority community in the near future. However, the economic trajectory suggests potential for change. If the upward trend in median income continues, it could attract more diverse populations, potentially leading to a transition towards a Moderate Diversity category over time. The economic changes and population growth might indicate the beginnings of a Transitional Community, which could manifest in gradual increases in other racial groups, particularly if economic opportunities continue to expand. The rapid income growth, if not evenly distributed, could lead to increased focus on income inequality within the Hispanic Majority population.

In conclusion, Harlingen currently fits the Low Diversity and Hispanic Majority categories. Its economic trajectory suggests potential for gradual demographic shifts. The city may be on the cusp of becoming a Transitional Community if current economic trends continue to attract a more diverse population. However, any such transition is likely to be slow, given the current overwhelming Hispanic majority.
