Explain the reasons for a decrease in the rate of illegal immigration in the United States in recent years

What will be an ideal response?

The rate of illegal immigration has decreased until 2007. The primary reason there has been a decrease is due to the drop in demand for unskilled labor since the 2007-2009 recession. Not only did the rate of immigration decrease, the rate of outflow, illegal immigrants returning to their home country, increased.
After the recession, the economic growth began to increase, but the net flow of illegal immigrants remained near zero. Economists have offered alternative reasons for this phenomenon. First, there has been a decrease in birth rates in areas that have typically immigrated to the United States. Second, economic growth in countries in which the illegals came from has begun to increase, creating greater labor demand in home countries. The North American Free Trade Agreement (NAFTA) has also opened opportunities in Mexico’s manufacturing sector. Mexican workers can now work at good-paying jobs that export products to the United States rather than relocate illegally to the U.S. Finally, U.S. immigration-enforcement activities have increased in recent years. All these factors working together have decreased the rate of illegal immigration in the United States.
