Geography of senior high school: urbanization rate after urban population migration

1, the migration of population will lead to the change of urbanization level (that is, the urbanization rate you mentioned). However, this migration is influenced by the change of economic level. If the economic level of this region does not change from high to low, the general trend of population migration will not change in a short time, and the level of urbanization can still be reflected in the level of economic development.

2. Negative population growth is the combination of natural growth rate and mechanical growth rate. It depends on whether the total population is increasing or decreasing. For example, the fertility rate in the United States is not high, but there are many immigrants, so there is no negative population growth. The strategy of countries with negative population growth such as Europe is to encourage fertility on the one hand and actively introduce immigrants on the other.
