Dollar store locations in the US

As dollar stores have proliferated, more babies have been named Luna, a correlation of 0.990 that connects discount retail to celestial baby naming with the unexpected poetry of a Dollar Tree beside a maternity ward. The stores multiply, the Lunas multiply, and the chart draws its line through the intersection of economic stratification and cultural aspiration. The dollar store serves one America, the baby name serves another, and the chart claims they are the same.

Dollar store locations grew from about 16,000 to over 38,000 between 2005 and 2022. Luna grew to over 7,500 babies per year. Both are smooth upward curves over eighteen years: dollar stores grow because economic inequality drives demand for discount retail, and Luna grows because the name's cross-cultural appeal expands. The correlation is purely shape-based—two monotonic trends sharing a period. The dollar store customer and the Luna parent may occasionally overlap, but the trends are driven by entirely different forces.

Eighteen years of dollar stores and Luna babies is one of the more socioeconomically dissonant correlations in the collection: one trend measures economic hardship, the other measures cultural aspiration, and the chart treats both as identical. The store opens in a struggling town, the baby is named in a thriving city, and the coefficient sees only the direction. The price is one dollar. The name is priceless.
