In total, the US Census reports data on over 150 ancestries. The interactive chart below allows you to explore how Biden’s vote share correlates with each of them (you can also see the correlation with people working in different occupations and industries). The Census’s data are based on a survey of 5% of the US population. Therefore, the ancestry and occupation data are not exact. For these data, only counties with at least 50,000 people are included to ensure accuracy. For these reasons, pay more attention to the trend of all of the counties, rather than any one specifically.
