China's Share of World Population: Over 18% and 1.4 Billion People

China is home to more than 18% of the world's total population, making it the most populous country on Earth with over 1.4 billion inhabitants as of recent estimates.

Demographic Context

This massive population represents approximately one in every five to six people globally. For decades, China held the #1 position unequivocally, though India has now reached a comparable population size and may have slightly surpassed it according to some 2023 UN projections.

Population Distribution

China's population is highly uneven distributed:

• Eastern coastal provinces (Guangdong, Shandong, Henan, Jiangsu, Sichuan) contain the vast majority of people.
• Western regions (Tibet, Xinjiang, Qinghai) are sparsely populated due to harsh geography and climate.
• Urbanization has accelerated dramatically—over 65% now live in cities, up from ~20% in 1980.

Demographic Shifts

China's population growth has slowed significantly due to the former one-child policy (1979–2015), rising living costs, delayed marriage, and changing social attitudes. The country now faces:

• An aging population (median age ~38, rising rapidly)
• Declining workforce
• Gender imbalance from historical son preference
• Policy shifts to two-child (2016) and three-child (2021) limits with limited effect so far

These trends have profound implications for China's economy, social security systems, healthcare, and global labor markets in the coming decades.
