Population aging is a long-term process, which depends on factors affecting fertility as well as other socio-economic factors including population policy. Many of our country's population and family planning policies have been implemented for a long time and significant results have been achieved: The total fertility rate (TFR) reached the replacement fertility level in the 2010s
Our country’s population has entered the golden population period, and after this period comes population decline. An analysis of the World Bank’s data on population growth and the annual TFR of our country and a few countries in the aged population period shows that the tendency toward a birth decline in Vietnam is still continuing. Therefore, the risk of population decline will be apparent in the coming years. Population policy is very important in increasing or decreasing the population of each nation. The population policy that aims at the birth decline in our country is not suitable anymore. Therefore, it is necessary to change the population policy in order to maintain the population at a stable increasing rate (TFR at 2.1
natural population growth at 0). Actively controlling the birth rate will positively affect the country’s socio-economic development.
