Texas surpassed 15 million registered voters this week, marking an all-time high for the state.

Texas Secretary of State Carlos H. Cascos’ office said the number of registered voters is 15,015,700 as of Thursday morning, approximately 78 of the state’s estimated voting age population.

“If you want to vote you must be registered, so it’s good to see that so many Texans are preparing for this November’s election,” said Cascos.

The Texas secretary of state’s office estimates the voting age population at 19,307,355, and the estimate “includes Texans who may not be eligible to vote such as non-citizens or convicted felons who have not yet fully discharged their sentence.”

Texas had 13.58 million registered voters in 2008 and 13.65 million registered voters in 2012. Ahead of the 2016 primaries in March, Texas had 14.2 million registered voters.

“Registration is just the first step,” said Cascos. “I encourage Texans to prepare now for this fall’s election.”
