The share of women aged 15–49 who are married or in a union and use any method of contraception. The indicator explains fertility better than income or education taken separately: in most countries the fall in fertility followed the rise of this share rather than the other way around. All methods are counted, including traditional ones, so the value is higher than the share using modern means.
Important: Only women in a marriage or a union — unmarried women are not in the denominator, and in countries where marriage comes late this noticeably changes the picture. The data come from household surveys, and the years are intermittent.
