The number of students attending public charter schools more than doubled between 2010 and 2020. In 2010, there were only 1.8 million students enrolled, but by the end of the decade, that number had grown to 3.7 million.
On the other hand, the number of students attending traditional public schools decreased by 109,000, while the percentage of all public-school students attending public charter schools increased from 3.6% to 7.5% during that same time period.
