The population has experienced a notable decline, decreasing from 3,345 in 2010 to 2,328 in 2022, a reduction of about 30.4%. This population decrease, coupled with the increase in median income, might indicate a shift in the community's composition, possibly due to outmigration of lower-income residents or an aging population remaining in the area.

Based on the observed trends, it is likely that Arthur will continue to be classified as a "Low Diversity" community in the near future. The consistently high percentage of white residents and minimal representation from other racial groups suggest that significant demographic shifts are unlikely in the short term.

Economically, if the current trends continue, further increases in median income might be expected. However, the declining population is a concern that could have long-term implications for the community's economic sustainability.

There is a possibility that Arthur could transition into a "Transitional Community" if it starts to attract more diverse residents, perhaps due to economic opportunities or changes in regional migration patterns. However, this would require a significant shift from current trends and would likely occur over an extended period.

While Arthur has experienced economic growth in terms of median income, its demographic composition has remained largely unchanged over the past decade. The most pressing challenge for the community appears to be its declining population, which could impact its long-term economic viability and potentially drive future demographic changes.
