Economic Development - Population: Net Migration, Immigration, and Emigration

This section defines key terms related to population movement, which are crucial for understanding economic development. Population changes significantly impact a country's economy, influencing labor supply, demand, and overall growth.

Definitions

Understanding the difference between these terms is fundamental to analyzing population dynamics.

• Immigration: The act of people coming into a country from another country to settle there permanently or for an extended period.
• Emigration: The act of people leaving a country to settle in another country permanently or for an extended period.
• Net Migration: The difference between the number of people who immigrate to a country and the number of people who emigrate from it in a given period. It represents the overall change in a country's population due to migration. $$ \text{Net Migration} = \text{Number of Immigrants} - \text{Number of Emigrants} $$

Key Terms Explained

Let's break down each term with more detail:

Immigration in Detail

Immigration often occurs for various reasons, including:

• Better economic opportunities
• Political or religious freedom

Immigrants can contribute to the economy by filling labor shortages, paying taxes, and starting businesses.

Emigration in Detail

Emigration can be driven by:

Emigration can lead to a loss of skilled workers and a decrease in the labor force in the emigrating country.

Net migration is a key indicator of population change. A positive net migration figure indicates population growth, while a negative figure indicates population decline. It's important to consider net migration alongside other factors like birth rates and death rates to fully understand population trends.
