As of July 25th, 2020, North Carolina had 7 million registered voters. Of these, 2.5 million or 36% were registered as a Democrat.
Older voters are the most likely to register as a Democrat, partly reflecting the legacy of the “Solid South.” Just over 43% of voters ages 75 and older are registered Democrats compared to 33% of 18-34 year-olds, 35% of 35-54 year-olds, and 39% of voters ages 55-74. As a result, older adults comprise a larger share of the state’s Democratic voters than the overall electorate.
Reflecting this age structure, North Carolina’s registered Democrats have the highest proportion of voters registered in 1990 or earlier: 17.9% compared to 16.6% of Republicans and 6.4% of unaffiliated voters.
Democratic voters are more diverse than the statewide electorate. Black voters comprise the largest racial/ethnic group among Democratic voters: 46% versus 21% statewide. White voters are the second largest group among registered Democrats (41% vs. 65% statewide).
Black voters are significantly more likely to register as a Democrat (79%) compared to other groups. Fifty percent of American Indian voters, 42% of Hispanic voters, 31% of Asian voters, and 23% of white voters are registered Democrat in North Carolina.
Carolina-born voters are more likely to be registered as a Democrat: 42% of South Carolina-born voters and 39% of North Carolina-born voters are registered as Democrats. Current NC voters born in the District of Columbia are the only group more likely to be registered Democrat (51%).
More than 1.1 million Democrat voters—45% of the state’s Democrat voter population—were born in North Carolina. New York (150K), other countries (91K), Virginia (68K), South Carolina (64K), and Pennsylvania (54K) were the next most common birth places. Eighteen percent of Democrat voters (444K) provided no information on place of birth.
Across North Carolina’s 100 counties, the county share of Democrat voters varies widely, reflecting county differences in composition by age, race/ethnicity, and place of birth. Reflecting the inverse of registration patterns for Republican voters, northeastern counties are most likely to register Democrat while many western counties are least likely to register Democrat. Two coastal Carolina counties—Currituck and Carteret—also have low shares of Democrat voters.
In four counties, more than two of every three registered voters is registered as a Democrat. Sixty-nine percent of registered voters in Hertford County are registered Democrat, the highest rate statewide. (Hertford also has the lowest share of Republican voters.) In contrast, Mitchell County has the lowest share of Democrat voters (10%) but the highest share of Republican voters.
