Fertility in countries in more developed regions averaged at 1.7 children per woman in 2010-2015. Fertility has also continued to fall in the vast majority of countries in less developed regions, and 41 of those countries had already reached below or replacement level fertility in 2010-2015. Yet, in 2010-2015, total fertility remained high at four children per woman or greater in 45 countries in less developed regions, including 17 countries where total fertility was five children per woman or greater (United Nations, 2013a).
