Zip code 51106 in Sioux City, Iowa, is classified as a "Low Diversity" area based on demographic data. As of 2022, the white population comprises 80% of the total 26,601 residents. The median income is $68,853, indicating a middle-class community.
Over the past decade, this zip code has maintained its "Low Diversity" status but shows signs of gradual transition. The white population decreased from 89% in 2013 to 80% in 2022. Other racial groups have shown small but steady increases. The Hispanic population grew from 7% to 10%, the Black population from nearly 0% to 5%, and those identifying as two or more races increased from 1% to 4%.
These trends suggest a slow but consistent diversification of the community. If current trends continue, the area may transition from "Low Diversity" to "Moderate Diversity" in the coming years.
The median income in the zip code has shown overall growth, increasing from $63,531 in 2013 to $68,853 in 2022, an 8.4% increase over nine years. This growth outpaces inflation for the same period, indicating a slight improvement in real income for residents. A significant spike in median income to $80,033 occurred in 2021, followed by a sharp decline in 2022.
The population has grown modestly, increasing from 24,987 in 2013 to 26,601 in 2022, a 6.5% increase. This growth suggests that the area remains attractive to new residents.
The trends observed in this zip code align with broader patterns seen in many midsize American cities. The gradual increase in diversity, particularly in Hispanic and multiracial populations, reflects national demographic shifts. However, the area's transition appears to be occurring at a slower pace than in many urban centers.
The steady economic growth, as reflected in the median income trends, suggests that the area has maintained relative economic stability even as it becomes more diverse. This could indicate that the demographic changes are not disrupting the local economy but may be contributing to its resilience and growth.
Zip code 51106 in Sioux City, Iowa, remains a predominantly white, low-diversity area, but shows clear signs of gradual diversification. This slow but steady demographic shift, coupled with modest economic growth, positions the community as a potential "Transitional Community" in the coming years.
