What Is GDP? Why Per Capita Is the Number That Counts
Your stagnant wages are not bad luck. UK output per person has barely moved since 2008. The US is now 30-40% ahead on the only GDP number that touches your salary.

Key takeaways
GDP (gross domestic product) is the total monetary value of all goods and services produced in a country in a given year. It is the broadest measure of national economic output.
For your bank account, GDP per capita matters more than headline GDP. GDP per capita is the total output divided by the population, and it tracks the size of the pie each person can claim.
US GDP per capita has pulled clearly ahead of the rest of the G7 since 2008. The UK now sits around 30-40% below the US on a per-person basis, and the gap is still widening.
Wages, public services, investment returns, job opportunities and tax burdens all flow from GDP growth in the long run. A stagnant economy is the single biggest invisible tax on your earnings.
