What problems will a negative population growth rate bring?

The direct consequence of negative population growth is that the labor force will be vacant or directly reduced.

1, the population growth rate is the population growth rate caused by natural changes and migration changes in a certain period of time (usually within one year). Population growth rate can also be called population growth rate. Whether population migration will cause changes in the total population size has certain regional conditions. For example, for a province, cross-provincial migration is not considered. Although there are frequent migrations between cities and counties in the province, this migration will not cause changes in the population of the province. Therefore, the population growth rate at this time is equal to the natural population growth rate. The population growth rate is usually used for census. By counting the population growth rate, a country or region can make clear its own population growth rate and population structure, so as to formulate corresponding population policies according to this ratio, and specifically decide whether to encourage fertility or control population and whether to solve the population problem. The aging or rejuvenation of the population and other issues.

2. Population growth includes natural growth and mechanical growth. Therefore, the factors affecting the population growth rate include these two aspects. Specifically, the birth rate, medical level, local average economic level and population migration range are direct factors. The education level in a region will affect the birth rate in that region (data show that the higher the average education level in a region, the lower the local birth rate). Medical care and economic level will also affect the birth rate and death rate. The scope of population migration mainly affects the mechanical growth of population. You said you'd seen enough, so I won't go into details.

The most obvious advantage of rapid population growth is that the population is updated quickly, avoiding population aging, social labor shortage, demographic dividend and so on. In addition, it can also alleviate the huge financial burden brought by the aging population. Its shortcomings are that population growth does not adapt to economic development, resulting in surplus labor, lower unit labor value, relative lack of resources and lower social security.

The difference between population growth rate and natural population growth rate is as follows:

1, different concepts.

The natural population growth rate refers to the ratio of the natural population growth rate in a certain period to the average total population in the same period, expressed in one thousandth. The natural population growth rate is an index reflecting the natural population growth trend and speed. The level of natural population growth depends on the change between birth rate and death rate.

Population growth rate is the population growth rate caused by natural changes and migration changes in a certain period of time (usually within one year). Population growth rate can also be called population growth rate.

2, the calculation method is different

What is the natural population growth rate?

Natural population growth rate = (number of births in the current year-number of deaths in the current year)/average annual population × 1000‰= population birth rate-population mortality rate, population birth rate = number of births in the current year/total population mortality rate = number of deaths in the current year/total population.

What is the population growth rate?

Population growth rate = (population at the end of the year-population at the beginning of the year)/average annual population × 1000.
