The community has maintained its "Low Diversity" classification throughout the observed period. However, minor changes in demographic composition are evident.

The demographic shifts have occurred concurrently with significant economic growth. The median income increase of 22.5% from 2013 to 2022 suggests overall economic prosperity.

Higher incomes may attract a more diverse population, increased diversity might contribute to economic growth, and rising incomes could potentially slow the pace of diversification.
