This article, ahead of the 2024 presidential election, analyzes the nearly 24 million naturalized citizen immigrant adults eligible to vote in the U.S. based on U.S. Census Bureau data. In 2022, 23.8 million naturalized citizens were eligible to vote, accounting for about 10% of the electorate, with their numbers growing steadily in recent decades compared to U.S.-born adults. Most have lived in the U.S. for over 20 years due to the lengthy citizenship process. Over half reside in California, Florida, New York, and Texas, and in 13 states and D.C., they make up at least 10% of eligible voters. Their share varies in potential 2024 battleground states. The top countries of origin are Mexico, India, China, the Philippines, and Vietnam. Most eligible naturalized citizens are Hispanic or Asian American. Demographically, they tend to be older, more likely to have a bachelor's degree, have slightly higher household incomes, and lower English proficiency compared to U.S.-born voters.
