197 1 year, the State Council approved the Report on Doing a Good Job in Family Planning, and included the target of controlling population growth in the national economic development plan for the first time. 1September 25th, 980, the Central Committee of China * * * issued an "Open Letter to all members of party member * * *", which explicitly mentioned "encouraging a couple to have only one child". From 65438 to 0982, the Twelfth National Congress of the Communist Party of China decided to implement family planning as a basic national policy of our country.

Since the implementation of the family planning policy, the population of China has increased by more than 400 million, which has achieved a historic change in the type of population reproduction ahead of schedule, effectively relieved the pressure of population on resources and environment, and effectively promoted economic development and social progress.

The strict implementation of national policies has helped China successfully avoid population out of control, but it has also brought some remarkable changes to China society. One of them is that with the implementation of family planning and the change of family consciousness, the only child has increased, the average family population has gradually decreased, and the family composition has shown a trend of miniaturization.

According to the survey of the National Office for Ageing, the average family population in China in 2005 was 1982, 4.4, 1995, 3.7 and 3. 13. In the past 23 years, the average family population has decreased by 1.27, with a decrease rate of about 28%. The miniaturization of urban family structure is more obvious, and this trend is more obvious.
