Economics has affected population patterns in the Americas in profound ways. Let us look at two of the types of ways in which this has happened.
First, economics has affected which countries have larger populations and population densities. This has occurred largely because the countries with better economies have been able to attract immigrants. For example, the United States, Canada, and Argentina have attracted large numbers of immigrants at various times while countries like Bolivia and Paraguay have not. In addition, some of the countries of the Americas have lost population to emigration. This is especially true of countries like Mexico and Honduras which have had many people leave to go to the United States.
Second, economics has affected population patterns within countries. One way in which this has happened is with the rise in urbanization. When countries become more industrialized, they also tend to become more urbanized. People move from rural areas to the cities to get jobs in the new factories. This changes population patterns within the countries.
Thus, economics has affected population patterns both across countries and within them.
