While the racial demographics have remained stable, there have been notable economic changes. The median income has grown from $55,772 in 2013 to $67,721 in 2022, representing a 21.4% increase over the decade. This growth outpaces inflation, suggesting a real improvement in economic conditions for residents. The population has shown some variability, ranging from a low of 4,641 in 2010 to a high of 5,628 in 2021. The 2022 population of 5,110 represents a slight decrease from the peak but still shows overall growth compared to the beginning of the decade. The stability in racial composition alongside increasing median income suggests that the economic improvements have primarily benefited the existing white majority population.

Montgomery's persistent low diversity contrasts with national trends towards increasing racial and ethnic diversity in many parts of the United States. This suggests the town may be somewhat isolated from broader demographic shifts occurring in more urban or rapidly growing areas. The median income growth observed in Montgomery is generally positive and may be in line with or slightly above national averages for similar small towns. The demographic stability of Montgomery may reflect broader patterns seen in many rural or small-town communities across the Midwest, where racial composition often changes more slowly compared to urban areas.

Montgomery presents a picture of demographic stability coupled with moderate economic growth over the past decade. Its persistent Low Diversity and White Majority status, combined with steady income improvements, suggest a community that has experienced economic development without significant changes to its racial composition. This pattern raises questions about the town's ability to attract or retain a more diverse population and how it might adapt to potential future demographic shifts that are occurring more broadly across the nation.
