The Puerto Rican nation's diaspora has been divided and has created multiple neighborhoods or barrios in Florida, along the East Coast of the United States, New York City and Chicago. These Puerto Rican mainland communities developed across the U.S. during Operation Bootstrap which gave way to the Great Puerto Rican Migration of the late 1940s and early 1950s. In 1968, branches of the Young Lords sprouted up in Chicago, New York, Philadelphia, Connecticut, New Jersey, Boston, Milwaukee, Hayward (California), San Diego, Los Angeles, and Puerto Rico.
