<h1>Global Demographic Challenges: Aging Populations and Declining Birth Rates Impact China, Japan, Italy, South Korea Economies.</h1> Countries worldwide, including China, Japan, Italy, and South Korea, are facing challenges of declining and aging populations. China's population has decreased for three consecutive years, with projections indicating further decline. Japan's population has been shrinking since 2008, with a significant drop in birth rates. Italy is experiencing historically low birth rates, prompting government campaigns to encourage childbirth. South Korea's population saw a slight increase due to foreign residents, despite a declining birthrate. These demographic shifts are leading to concerns about economic impacts, labor shortages, and increased pressure on social systems, prompting governments to implement various incentives and policy changes.
