Population Growth and Family Planning PPT, Part Three: Family Planning
China is the most populous developing country in the world, with a population of 1.29227 billion people of 56 ethnic groups living in a vast territory of 9.6 million square kilometers (2003).
China's population accounts for 21% of the world's population, but its cultivated land area only accounts for 7% of the world's. There is a sharp contradiction between the huge population base and annual population growth and economic and social development, resource utilization and environmental protection. The implementation of family planning has controlled the excessive growth of the population and promoted the coordinated development of population, economy, society, environment and resources. At the same time, it has also improved the quality of life of citizens and ensured them a better space for survival and development.
The basic content of family planning is to control the population and improve the quality of the population. There are eight specific ways to control population growth: late marriage, late childbearing, fewer children, and eugenics.
