Although there are continuous progresses in economy and society, the accelerated aging process has brought widespread impacts on various aspects of society and economy in China, especially on the supply of the working-age population. Effectively addressing labor force aging has become an urgent challenge for China's economic and social development. North American countries, particularly the United States and Canada, are also facing severe aging population issues, and have entered an aging society earlier than China. These countries have alleviated labor supply shortages through proactive immigration policies, while implementing flexible retirement, reemployment of elderly individuals, and vocational training policies to effectively encourage elderly workers to remain in their jobs. Additionally, the occupational health programs of large enterprises in North America have yielded positive returns on their health investments. Building upon an overview of the current situation and corresponding measures in response to the aging working-age population in North America, this paper presented constructive recommendations to address the aging population issue in China.
