The population has seen a general decline, from a high of 2,034 in 2012 to 1,575 in 2022, a 22.6% decrease. This population loss correlates with the decline in median income, suggesting possible out-migration due to economic factors.

The lack of racial diversity change in Mammoth contrasts with national trends. The economic decline observed since 2017 may reflect broader challenges faced by small, rural communities in Pennsylvania and across the United States, such as the loss of traditional industries or changing economic landscapes.

Based on observed trends, Mammoth will likely remain a "Low Diversity" community in the near future, given the long-standing racial homogeneity. However, the economic challenges evident in the declining median income and population loss could lead to further demographic changes. If the downward economic trend persists, it may lead to further population loss as residents seek opportunities elsewhere.

Prolonged economic challenges could eventually lead to demographic shifts if the area becomes attractive to new populations seeking affordable housing. This could potentially move the community towards a "Transitional Community" status in the long term, especially if efforts are made to diversify the local economy and attract new residents.

With a declining population and lack of in-migration, the community may face challenges related to an aging population, which could further impact economic dynamics and community services.

Mammoth has maintained its racial composition, but its economic trajectory presents significant challenges. The community's future will likely depend on its ability to stabilize its economy and potentially diversify its economic base to attract new residents and opportunities.
