As US GDP per capita has grown, UK pint prices have risen, a transatlantic correlation of 0.979 that connects American wealth to British beer costs with the economic confidence of two developed nations getting richer and more expensive at the same rate. The GDP climbs in Washington, the pint inflates in Westminster, and the chart draws a line through both economies without obtaining a visa.
GDP per capita grew from about $49,000 to over $76,000 between 2010 and 2022. UK pints grew from about £3.00 to over £4.60. Both are measures of economic growth and inflation in developed economies: America's GDP rises because its economy grows, Britain's pint price rises because its costs rise. The shared variable is the same global economic expansion that inflates everything in both countries.
Eleven years of American GDP and British beer is the most straightforward transatlantic economic correlation: wealth grows in one country, prices grow in another, and both are measuring the same global economy from different angles. The income rises, the pint inflates, and the chart is simply an exchange rate expressed through economics and alcohol.
