Final answer:
Turnout of registered voters above 90 percent is uncommon in the United States, with the highest being 77 percent in the 2020 election. High turnouts over this threshold are more typical in countries with compulsory voting laws or automatic voter registration, such as Belgium, Turkey, Sweden, and Germany. The U.S. ranks low in voter turnout among OECD countries.
Step-by-step explanation:
The turnout of registered voters reaching over 90 percent is not typical in the United States. The highest voter turnout ratio tends to be calculated using the smallest population group: registered voters. For instance, during the 2020 presidential election, 77 percent of registered voters cast their ballots. To achieve a turnout above 90 percent among registered voters is quite rare in the U.S. and typically observed in countries with compulsory voting laws, such as Belgium and Turkey, which have turnout rates around 87 percent and 86 percent, respectively.
In contrast to the registered voter turnout, the percentage of the voting-eligible population (VEP) that voted was 67 percent in 2020. Moreover, when considering the voting-age population (VAP), the figures drop even further. Countries like Sweden and Germany, which automatically register their voters, have seen higher turnouts, achieving around 83 percent and 66 percent respectively. Voter turnout can also vary significantly by race, Hispanic origin, age, income, and education level.
It is worth noting that while the United States has seen an increase in voter registration and actual votes cast, especially in the 2020 election, its voter turnout still lags behind many other OECD countries, ranking 30th out of 35. The number of votes cast in the 2020 election increased significantly, mostly due to a large increase in registration numbers, even though a smaller percentage of registered voters voted compared to previous elections.
