Final answer:
China fits into the demographic transition due to economic and social changes, one-child policy, and rural-to-urban shift.
Step-by-step explanation:
China fits into the demographic transition due to its significant economic and social changes over the years. It has transitioned from a command economy to a market economy and has encouraged international trade, which has provided more opportunities for its people. The country also implemented a one-child policy to control population growth, resulting in a decrease in birth rates. Additionally, China has experienced a rapid rural-to-urban shift, with a large percentage of its population moving from rural areas to cities for employment opportunities.
