A significant increase in median income occurred between 2015 and 2016, rising from $53,332 to $60,582. The highest median income was recorded in 2018 at $71,527. There was a decline in median income from 2018 to 2019, dropping to $64,327. The most recent years (2020-2022) have shown relative stability, with minor fluctuations.

Population figures have fluctuated over the decade, peaking at 1,864 in 2018 and declining to 1,435 by 2022. This recent population decrease could potentially impact the local economy and services.

Calumet's demographic homogeneity is unusual in an increasingly diverse United States. The lack of significant demographic change in Calumet over a decade suggests it may be a more isolated or rural community, less affected by broader demographic shifts occurring nationwide.

Based on the observed trends, it seems likely that Calumet will remain a "Low Diversity" community in the near future. The consistency of the racial composition over the past decade suggests demographic patterns that are unlikely to change dramatically without significant external factors.

Economically, if the recent trend of population decline continues, it could put pressure on the local economy and potentially lead to a stagnation or decline in median income. However, if the community can attract new residents or industries, it might see continued growth in median income.

Given the slight increase in residents identifying as two or more races, there is a possibility that Calumet could very slowly transition towards slightly more diversity. However, based on current trends, any such transition would likely take many years to manifest significantly. The most likely scenario is that Calumet will remain in the "Low Diversity" category for the foreseeable future, with potential for very gradual movement towards "Moderate Diversity" over a long period if current minor trends continue and accelerate.
