a

b
Fifty-eight women (60%) reported using no method of contraception. The denominator for the proportions of women using each contraceptive method type is the total number of women reporting use of any method. Because women could report multiple methods, proportions sum to greater than 100%.
c
Among women who report any lifetime sex with women.
