According to the National Survey on Sexual Health and Contraception among Spanish Youth, promoted by the Spanish Society of Contraception (SEC), 29,7% of young women have ever used emergency contraception (EC) pills. These figures vary when broken down by ages: 14,4% of 16 to 18 years old have ever used EC; 19,9% of 19 to 21 years old; and 34,5% of 22 to 25 years old.
