Many individuals who oppose illegal immigration and promote efforts to eradicate illegal immigrants argue that illegal immigration has caused overpopulation in the United States.
Overpopulation statistics indicate that, on average, the entire world is suffering from overpopulation, and as a result, necessary resources are becoming increasingly scarce. The exact number of illegal immigrants residing in the United States is not certain, however, it has been estimated that somewhere between 10 million and 20 million illegal immigrants are currently residing in the country.
Though this is a large number, when compared to the 280 million U.S. citizens residing in the country, it is relatively small. Recent estimates suggest that there are only 10.8 million illegal immigrants currently living in the U.S. This accounts for a very small percentage of the U.S. population. Therefore, it is not accurate to suggest that illegal immigration has caused overpopulation in the U.S. The extensive U.S. population, the high reproduction rate, successful medical treatment, and increased life expectancy have caused overpopulation in the U.S.
