Editing Demographic transition (section)

====China====
China experienced a demographic transition with high death rate and low fertility rate from 1959 to 1961 due to the great famine.<ref name=":3" /> However, as a result of the economic improvement, the birth rate increased and mortality rate declined in China before the early 1970s.<ref name=":4" /> In the 1970s, China's birth rate fell at an unprecedented rate, which had not been experienced by any other population in a comparable time span. The birth rate fell from 6.6 births per women before 1970 to 2.2 births per women in 1980.The rapid fertility decline in China was caused by government policy: in particular the "later, longer, fewer" policy of the early 1970s and in the late 1970s the one-child policy was also enacted which highly influence China demographic transition.<ref>{{cite journal|last1=John|first1=Bongaarts|last2=Susan|first2=Greenhalgh|date=1985|title=An alternative to the One-Child Policy in China|url=https://www.jstor.org/stable/1973456|journal=Population and Development Review|volume=11|issue=4|pages=585–617|doi=10.2307/1973456 |jstor=1973456 }}</ref> As the demographic dividend gradually disappeared, the government abandoned the one-child policy in 2011 and fully lifted the two-child policy from 2015.The two-child policy has had some positive effects on the fertility which causes fertility constantly to increase until 2018.However fertility started to decline after 2018 and meanwhile there was no significant change in mortality in recent 30 years.
