Changing fertility patterns in China

China's recent fertility data collected from the 2020 population census and 2017 fertility survey have considerably improved in quality. Based on these, we can assess the levels and patterns of fertility with high confidence. We reconstruct China's fertility history from 1990 using these two types of data and review the trends and characteristics of fertility transitions and changing fertility patterns in China. Over the past half century, China has experienced an extraordinary fertility transition and decline, which can be described as three stepwise downward jumps in fertility that occurred in the 1970s, 1990s, and 2010s. While the tempo effect has always depressed fertility, the quantum effect became positive in the most recent fertility decline, when China made successive adjustments to its fertility policy. Age, parity, and interval patterns of fertility in China have also undergone fundamental changes influenced by changing fertility policies and rapidly expanding higher education. The recent rapid decline in fertility is driven by the increasing postponement of marriage, a large reduction in fertility for lower education groups, and a rising proportion of younger women accessing higher education.
