Population figures have fluctuated in Scarville. In 2013, there were 221 residents. The population peaked at 273 residents in 2018 and declined to 216 residents in 2022. The population growth from 2013 to 2018 might have contributed to the increased diversity and rising median income. The subsequent decline in population coincides with a decrease in Hispanic representation and a slight dip in median income.

Scarville's "Low Diversity" status is not uncommon for small, rural Midwestern communities, which often have predominantly white populations. The median income of $70,945 in 2022 is above the national median household income, suggesting relatively good economic conditions despite the small population. The subtle increase in diversity, even if temporary, aligns with broader national trends of increasing diversity in rural areas, albeit at a much slower pace than urban centers. The population decline in recent years mirrors trends seen in many small rural communities across the United States.

In conclusion, Scarville has maintained its status as a "Low Diversity" area with a strong "White Majority" over the past decade, experiencing minor demographic shifts and economic fluctuations. These changes reflect broader trends of slow diversification and economic challenges faced by small rural communities. The correlation between periods of increased diversity and higher median incomes suggests potential economic benefits from even modest increases in diversity.
