US GDP per capita

As GDP per capita has grown, beard care product revenue has grown, a correlation of 0.976 that connects national wealth to facial grooming with the economic confidence of a chart that treats income growth and beard oil as equivalent measures of prosperity. The nation gets richer, the beards get oilier, and both numbers climb because a wealthy economy produces both more disposable income and more products to dispose of it on.

GDP per capita grew from about $52,000 to over $76,000. Beard care grew from about 5 billion to over 30 billion between 2012 and 2022. Both eleven-year curves. Beard care is a luxury grooming category that scales directly with disposable income: men who can afford beard oil buy beard oil, and more men can afford it as GDP grows. The correlation is partially causal—income enables spending on discretionary grooming products.

Eleven years of GDP and beard care is a correlation with a real economic mechanism: higher income enables discretionary spending on grooming products, and beard care is one of the most income-elastic categories in personal care. The beard grows, the income grows, and the beard oil purchase is enabled by both.
