Final answer:
Economic development and government policies are two main factors that can change a country's population. Economic development attracts people in search of jobs, leading to immigration, while government policies on healthcare can affect mortality rates and life expectancy, impacting population growth.
Step-by-step explanation:
Two kinds of factors that can change a country's population are economic development and government policies. Economic development can lead to job creation, which can attract people from other regions, thereby increasing the population through immigration. For instance, the industrialization process often leads to urbanization, where rural populations move to cities in search of better job and educational opportunities. On the other hand, government policies such as those related to family planning, healthcare, and immigration can have a significant impact on population dynamics. For example, proactive healthcare policies can reduce mortality rates and increase life expectancy, contributing to population growth.
Additionally, government policy can also stimulate economic growth by investing in sectors that create employment opportunities, thereby attracting people from less developed areas or other countries. This economic growth leads to a rise in population due to immigration. Conversely, policies that restrict immigration can slow down population growth.
