A New York Times examination of lottery documents, as well as interviews with lottery administrators and analysts, finds that lotteries accounted for less than 1% to 5% of the total revenue for K-12 education last year in the 23 states that use lottery money for schools. Most of the money raised by lotteries is used to sustain the games themselves. And as they compete for a small number of core players and try to persuade occasional customers to play more, nearly every state has increased, or is considering increasing, the size of its prizes, further shrinking the share of each dollar going to education and other programs.
