Population figures have remained stable, fluctuating between 6 and 8 residents over the decade. This stability in population, combined with the consistent racial makeup, suggests a lack of significant in-migration or out-migration.

West Millgrove's demographic profile is atypical when compared to broader trends. While many areas across the United States have been experiencing increasing diversity and urbanization, West Millgrove has maintained its homogeneous, rural character. The village's median income in 2022 ($86,183) is higher than the national median household income (approximately $70,784 in 2021). However, given the small population, this figure may be skewed by one or two high-earning households.

Communities this small often face challenges in economic development, provision of services, and maintaining population. The fact that West Millgrove has maintained a stable population over the decade, despite its size, is noteworthy. West Millgrove does not reflect broader trends towards increased diversity seen in many parts of the country. Its ability to maintain a stable population and relatively high median income in recent years is notable for a community of its size. However, the small population size makes it difficult to draw broader conclusions or identify significant demographic trends from this data.
