Tomales appears to be moving in the opposite direction of national trends that often show increasing diversity. This divergence could be due to several factors. Its small population size makes it more susceptible to rapid demographic shifts from minor changes in resident composition. The significant increase in median income might be pricing out more diverse, lower-income residents, contributing to the decreased Hispanic population. The rural nature of the CDP may contribute to its unique demographic trends compared to more urban areas.
