Saltillo's demographic composition is not typical of many urban areas in Pennsylvania, which tend to have more diverse populations. The borough's racial homogeneity and recent economic growth may reflect trends seen in some rural or semi-rural areas that are beginning to experience modest diversification and economic development.

Based on the observed trends, it is likely that Saltillo will remain in the "Low Diversity" category for the foreseeable future. However, if the subtle trend towards increased diversity continues, a gradual transition towards a "Moderate Diversity" category over the next decade or two might be observed. This transition would likely be accompanied by a continued increase in the percentage of residents identifying as two or more races, potential growth in other minority populations, and a gradual decrease in the white population percentage, though remaining the majority.

Economically, if the upward trend in median income continues, it could further attract a more diverse population seeking economic opportunities. However, given the small size of the community, any changes are likely to be gradual and may take many years to significantly alter the demographic landscape.

Saltillo shows signs of incremental diversification and economic growth, but remains a predominantly white, low-diversity community with a steadily improving economic outlook. The coming years may see a slow but steady shift towards more diversity, potentially setting the stage for a transition to a more moderately diverse community in the long term.
