Abstract for: Visualization of aging and shrinking trends in China's population through 2060

According to UN records, China has been the most populous country on earth since 1950; however, this trend is expected to change in 2023. At the end of 2022, the population of China stood at 1.41175 billion, a decrease of 850,000 compared to the population at the end of 2021. This is notable because it is the first time China's population has seen negative growth since 1961. China’s death rate has surpassed its birth rate. For this reason, it is important to investigate the size and speed of the population shift. Using System Dynamics modeling, we estimate the future size of China’s population, the future size of the workforce, the future population structure, and the burden the workforce will bear to financially support non-working people over 65 years old (China Pension System). We hope that our modeling can contribute to the creation of sound policies so that China can meet its development goals.
