Nearly 1 million registered voters added in Dallas-Fort Worth since 2016

The big picture: The region has some of the fastest-growing counties in the nation, with the population booming especially in the suburbs and exurbs. 

• Denton is now the seventh Texas county with a population over 1 million, per U.S. Census Bureau data.

State of play: Voter registration drives appear to have worked. At least 167,000 more North Texans are registered to vote now than were for the March primaries. 

• Since Trump first ran for president in 2016, the four most populous North Texas counties have added more than 815,000 registered voters. 

Zoom out: Some of the outlying counties, including Kaufman and Rockwall counties, have seen huge population growth that is mirrored in their increases in registered voters. 

• Kaufman, the fastest-growing county in the country, added more than 40,000 registered voters since 2016. 

Stunning stat: Tarrant County has added the most registered voters since 2016, with 224,072. 

• That's almost equivalent to the Irving population. 

Reality check: About a quarter of registered voters are unlikely to cast a ballot. 

• For example, about 68% of registered voters in Tarrant County voted in 2020.
