Sustainable economic development is one of the key issues today. There are many factors affecting the development of the economy. Among all the causes, population structure is one of the most significant factors affecting economic development. However, the population structure changes hinder the sustainable economy’s development. Therefore, more and more people pay attention to population structure. Nowadays, most of the countries in the world are facing population aging, population mobility issues, or some other population problems. The paper will analyze the impact of population structure on economic development first. Furthermore, the paper will provide reasonable solutions to the corresponding problems through specific examples. Population Aging is one of the most serious population structure problems. For sustainable development, governments need to control the proportion of the elderly. Population Mobility is a quite common phenomenon. With the trend of population mobility, economic development is also changing. To improve the average economic level of all the cities, the governments need to formulate policies to attract comprehensive population mobility, rather than one-way mobility.
