The median income in Tarentum has shown overall growth, albeit with fluctuations. From 2013 to 2022, median income increased from $47,238 to $53,146, a growth of about 12.5%. The period from 2018 to 2021 saw the most significant income growth, coinciding with a slight increase in diversity. However, there was a noticeable drop in median income from 2021 to 2022 (from $56,484 to $53,146), corresponding with a decrease in diversity and a strengthening of the white majority.

Population has steadily declined from 4,567 in 2010 to 4,328 in 2022, a decrease of about 5.2%.

Tarentum's demographic makeup differs significantly from national averages. The U.S. as a whole has been trending towards greater diversity, with the white population decreasing to about 60% nationally. Tarentum's 89% white population in 2022 indicates it is significantly less diverse than the national average. The median household income in the U.S. was approximately $70,784 in 2021, suggesting that Tarentum's median income of $53,146 in 2022 is notably below the national average.

Based on the observed trends, Tarentum is likely to maintain its Low Diversity, White Majority status in the near future. However, the consistent growth of the Hispanic population and the historical fluctuations in diversity suggest that the community may slowly transition towards Moderate Diversity over the next decade.

Economically, if the trend of income growth resumes after the 2021-2022 dip, the borough might see gradual economic improvement. However, the declining population could pose challenges to economic growth if it continues.

In conclusion, while Tarentum has shown some signs of increasing diversity and economic growth over the past decade, recent trends indicate a reinforcement of its Low Diversity, White Majority status. The community's future may involve a slow transition towards greater diversity and modest economic growth, but significant changes are unlikely in the short term without major demographic or economic shifts.
