Seneca, Illinois, is a low diversity community with a white majority. As of 2022, the white population comprises 89% of the total, categorizing the city as a "Low Diversity" area. The city's median income was $92,455 in 2022, indicating a relatively affluent community, though this represents a decrease from the previous year.
Over the past decade, Seneca has maintained its status as a "Low Diversity" community. The white population has remained above 75% throughout the period, declining from 96% in 2017 to 89% in 2022. This gradual decrease indicates a slow trend towards increased diversity.
The Hispanic population has shown the most significant growth among minority groups, increasing from 2% in 2019 to 6% in 2022. Small but growing Asian, Black, and multiracial populations have also emerged, suggesting the beginnings of a more diverse community composition.
The median income in Seneca has grown over the past decade, rising from $77,674 in 2013 to a peak of $104,220 in 2021, before decreasing to $92,455 in 2022. This economic trajectory generally correlates with the gradual increase in diversity. The population has fluctuated, peaking at 5,039 in 2018 before declining to 4,646 in 2022.
The trends observed in Seneca align with patterns seen in many suburban communities across the United States. The gradual increase in diversity, coupled with rising incomes until the recent decline, reflects a common trajectory for communities transitioning from homogeneous suburbs to more diverse areas.
Based on observed trends, Seneca appears to be in the early stages of a transition towards greater diversity. If current trends continue, it could transition into a "Moderate Diversity" category within the next 5-10 years. This would likely involve continued growth in the Hispanic population, along with modest increases in other minority groups.
The recent decline in median income requires monitoring. If it represents a temporary fluctuation, the city may return to its upward income trajectory. However, if it marks the beginning of a new trend, it could impact the pace of demographic change, potentially slowing the diversification process.
In conclusion, Seneca remains a predominantly white, affluent community, but subtle shifts in its demographic makeup hint at a slow but steady move towards greater diversity. This evolution, if continued, could reshape the community's character and economic landscape in the coming years.
