The chart above shows the annualized nominal gross domestic product (GDP) growth rate when the GDP is priced in US dollars in each EU and US state over the past five years as of the first quarter of 2021 and the growth rate over the past ten years. Four states had negative growth over the past ten years while zero had negative growth over the past five.

## Findings

- The difference between the state with the largest annualized five-year growth rate, Ireland, and the state with the smallest, Greece, is 12.77 percentage points.
- The difference between the state with the largest annualized ten-year growth rate, Ireland, and the state with the smallest, Greece, is 13.95 percentage points.
- The median annualized five-year growth rate in the 28 EU states is 5.79% and the mean 6.46%. The median annualized ten-year growth rate in the 28 EU states is 1.46% and the mean 2.32%.
- The median annualized five-year growth rate in the 50 US states is 3.39% and the mean 3.71%. The median annualized ten-year growth rate in the 50 US states is 3.90% and the mean 3.96%.
- The median annualized five-year growth rate in the 78 EU and US states is 4.00% and the mean 4.70%. The median annualized ten-year growth rate in the 78 EU and US states is 3.59% and the mean 3.37%.
- Of the 78 states, 46 grew faster over the past five years than they did over the past ten years (28 from the EU, 18 from the US), 1 had the same annualized growth rate over both periods (0 EU, 1 US), and 31 grew slower over the past five years than they did over the past ten years (0 EU, 31 US).
- Some EU drops and gains in GDP growth rate are attributed to currency rate fluctuations.

## Caveats

- Data is from the first quarters of 2011, 2016, and 2021.
- The data is seasonally adjusted in current dollars.
- Euros are converted to dollars at an average exchange rate of 1.21 for the first quarter of 2021, 1.10 for the first quarter of 2016, and 1.37 for the first quarter of 2011 according to historic rates listed at the Federal Reserve (see source link below).
- US data comes in an annualized format which the EU does not, thus EU data is annualized by multiplying the quarterly figure by four.
- US growth rates may differ from those provided by the Bureau of Economic Analysis as the BEA's growth rates are based on chained dollars in conjunction with the chain index or the quality index for real GDP. The growth rates listed here are based on nominal GDP.
- All figures are rounded to the nearest hundredth.
