Recent fertility changes in Mongolia: What can we learn from examining tempo-adjusted fertility?

Abstract

Between 1990 and 2015, several post-communist countries experienced a decline in fertility, followed by a rise in the period fertility rate of roughly one child per woman. Mongolia is a good case-in-point. Its period fertility dropped further after the demise of socialism in 1990 but has increased again since 2005 and fluctuated around 3.0 children per woman in recent years. Political factors have been suggested as the explanation of these changes. This research investigates whether demographic factors also provide explanations for the period fertility changes in Mongolia. We study this through reconstructing the fertility rates, by age and birth order, from data collected by several social and demographic surveys. The fertility rates are adjusted to examine the role of tempo effects in recent fertility changes. The results show that the demographic influences, in particular childbearing postponement and recuperation, have contributed to recent changes in fertility trends and levels in Mongolia.
