Answer:
The state that has experienced a relatively large influx of Mexicans in recent decades and was featured in Immigrant Nation is Illinois.
Explanation:
The State of Illinois is one of the states that receives the most foreign immigrants throughout the United States. This is mainly because Chicago, the most important city in the state and the third most populous city in the nation after New York and Los Angeles, is one of the most important economic (and therefore labor) poles in the country.
According to statistics from the Census Bureau, 10% of the population of Illinois corresponds to descendants of Mexicans. In turn, 5% of the population of the state was born in Mexican territory. This situation increases in the Chicago Metropolitan Area, where 15% of the population is descended from Mexicans. Even in the city of Cicero, this percentage of descendants of Mexicans rises to 80%.
