Two performance indicators used interchangeably are maternal mortality ratio and maternal mortality rate, both abbreviated as "MMR". By 2017, the world maternal mortality rate had declined 44% since 1990, but still every day 808 women die from pregnancy or childbirth related causes. According to the United Nations Population Fund (UNFPA) 2017 report, this is equivalent to "about one woman every two minutes and for every woman who dies, 20 or 30 encounter complications with serious or long-lasting consequences. Most of these deaths and injuries are entirely preventable."
