Chapter 4: Problem 4

What are immigration and emigration? Do they impact worldwide population or just local population sizes?

Short Answer

Expert verified

Immigration is the movement of people into a country or region, while emigration is when people leave a country or region to settle elsewhere. They do not significantly impact worldwide population sizes but do redistribute the population across countries or regions. However, they have a noticeable effect on local population sizes, influencing population dynamics and affecting local economies and societies.

Step by step solution

Define Immigration and Emigration

Immigration refers to the phenomenon in which people move into a country or region. This can be due to various reasons such as job opportunities, education, or to reunite with family. On the other hand, emigration is when people leave a country or region to settle elsewhere for the same reasons or other aspects, such as search for better living conditions, political reasons, or escaping conflicts like war or persecution.

Examples of Immigration and Emigration

Let's consider a few examples: 1. Immigration: A family from country A migrates to country B in search of better job opportunities and improved living conditions. This is an example of immigration into country B. 2. Emigration: A couple from country C decides to leave and relocate to country D for educational purposes, as the universities in country D offer better programs in their field of interest. This is an example of emigration from country C.

Impact on Worldwide Population Sizes

Immigration and emigration do not significantly impact worldwide population sizes, as they represent the movement of people from one place to another. However, factors such as birth rates, death rates, and access to resources play a larger role in determining the overall global population growth. What immigration and emigration do is redistribute the population across different countries or regions.

Impact on Local Population Sizes

Immigration and emigration have a more noticeable effect on local population sizes. Immigration can lead to an increase in the population of a country or region, which can potentially create more demand for housing, jobs, resources, and services. In contrast, emigration can lead to a decrease in population, which may result in labor shortages, reduction in tax revenue, and decrease in demand for goods and services. Thus, immigration and emigration strongly influence the population dynamics of specific regions, and can have varying consequences on local economies and societies.
