Population changes have been minimal, increasing from 2 individuals in 2010-2017 to 3 individuals from 2018 onwards. This slight increase does not correlate directly with the income fluctuations, suggesting that external economic factors rather than population changes are driving income trends.

The extremely small population of Sprague makes it an outlier in demographic studies. Most communities have significantly larger populations that allow for more meaningful diversity analysis and economic trend observations.

The median income, despite its recent decline, remains above the national median household income. However, with such a small population, individual circumstances can dramatically affect these figures, making year-to-year comparisons less reliable than in larger communities.

The lack of racial diversity in Sprague contrasts with national trends towards increasing diversity in many rural and suburban areas. Extremely small communities like this one often maintain more homogeneous populations due to limited in-migration and the significant impact that even one new resident of a different racial background would have on overall demographics.

Sprague maintains a stable, low-diversity racial profile, while its economic situation has seen notable fluctuations. The community's extremely small size makes it challenging to draw broader conclusions or to apply standard demographic analysis tools effectively. This case underscores the importance of considering scale when analyzing demographic and economic trends, especially in very small rural communities.
