Final answer:
True statements about immigration to Mexico include the effects of the 1986 Immigration Reform and Control Act, territory loss due to the Treaty of Guadalupe Hidalgo, and economic contributions through remittances from Mexican workers in the United States.
Step-by-step explanation:
Several statements about immigration to Mexico have been provided, and each needs to be carefully considered to determine its truthfulness. To address the question, we need to look at the statements individually:
- Immigration reform and control - Sociologist Douglas Massey highlighted that the 1986 Immigration Reform and Control Act, intended to reduce migration, paradoxically increased the flow of illegal one-way immigration from Mexico to the U.S.
- Treaty of Guadalupe Hidalgo - As a result of this treaty, it is true that Mexico lost over half of its territorial land mass to the United States (Exercise 14.2.3, option a).
- Remittances to Mexico - A significant portion of immigrants from Mexico to the U.S. are involved in the workforce, and they send back billions of dollars each year to Mexico (option b from the question on money flows), which is a vital part of Mexico's economy.
With this information, the true statements concerning immigration to Mexico are that the Immigration Reform and Control Act of 1986 led to an increase in one-way illegal immigration, the Treaty of Guadalupe Hidalgo resulted in Mexico losing a significant amount of its territory, and Mexican workers in the U.S. contribute financially to the Mexican economy through remittances.
