Final answer:
The majority of Puerto Ricans live in New York City, East Harlem, Chicago, and Miami. Cuban Americans have a significant presence in Miami, Florida.
Step-by-step explanation:
The majority of Puerto Ricans live in New York City, East Harlem, Chicago, and Miami. Puerto Ricans have been migrating to American cities since the 1940s due to the expansion of US companies in Puerto Rico. By 1960, Puerto Ricans made up nearly 10 percent of New York City's population.
Cuban Americans, on the other hand, have a significant presence in Miami, Florida. Many Cubans migrated to the US after Fidel Castro came to power in 1959. They found refuge and became active in local politics and professional life.
