The percentage of individuals identifying as two or more races has fluctuated between 1-3% over the decade. A small Asian population (1%) appeared in the data from 2021 onwards. These changes suggest a very slow trend towards slightly increased diversity, though not enough to shift the community out of the "Low Diversity" category.

This stability in population, combined with the gradual increase in median income, suggests a relatively steady economic environment.
