In September 2013, the Spanish Society of Contraception (SEC) published the study ESTUDIO POBLACIONAL SOBRE USO Y OPINIÓN DE LA PÍLDORA POSTCOITAL 2013, which assesses women’s knowledge, opinions, and use of emergency contraception pills (ECPs) in Spain among 14 to 50 year olds. The study was conducted by SIGMA DOS and sponsored by Chiesi and is a follow up to a similar study conducted in 2011 which you can see here.
The study found that 16.6% of women of reproductive age have ever purchased ECPs, and 14.7% have ever used ECPs (this increased from 14.1% in 2011). The use of ECPs is associated with being in an emergency situation, primarily due to contraceptive failure (78.9%), usually the condom. Read the full 2013 survey report here (in Spanish only).
