Here to compare the % of population ages 65 and older and healthcare expenditure as a % of GDP.
United States
1960: 9.1%
2017: 15.4%
The number of Americans ages 65 and older is projected to more than double from 46 million today to over 98 million by 2060, and the 65-and-older age group’s share of the total population will rise to nearly 24 percent from 15 percent.

Healthcare expenditure rose from 5% of GDP in 1960 to 17.9% in 2017.
China
1960: 3.7%
2013: 9%
2017: 10.6%
By 2050, 330 million Chinese will be over age 65.
The population ages 60+ will reach its highest in 2050: nearly 35%, at 487 million
预计到2025年，我国60岁及以上老年人口数将达到3亿，占总人口的五分之一；到2033年将突破4亿，占总人口的四分之一左右；而到2050年前后将达到4.87亿，约占总人口的三分之一，老年人口数量和占总人口比例双双达到峰值。
Healthcare expenditure mainly ranges from 4% to 5% from 2000 to 2016, rising constantly in recent years. Considering the rapid growth in its GDP, the healthcare expenditure in China is growing fast.
The percentage of GDP is expected to rise to more than 26% for elders’ caring related costs. [2015-2050年，我国用于老年人养老、医疗、照料等方面的费用占GDP的比例将从7.33％升至26.24％]
Just by comparing China to US, China’s healthcare expenditure percentage is a little lagging behind (~10% 65+ population for 7% healthcare GDP). But the opportunity is large as Chinese demographic is changing rapidly. With the historical “one child policy”, China’s working population will experience a “squeeze”.
