Philadelphia has been a heavy Puerto Rican destination since the 1950s, though migration to the city has picked up and now Philadelphia has one of the fastest-growing Puerto Rican populations in the country. Puerto Ricans constitute over 75% of the Latino population in the city. Most Puerto Ricans live in the areas of North Philadelphia east of Germantown Avenue (eastern North Philadelphia), and to a lesser extant the Lower Northeast and Uptown sections of the city. In fact, the Fairhill section of Eastern North Philadelphia, particularly the blocks between 6th Street and B Street, north of York Street and south of Erie Avenue, have some of highest concentrations of Puerto Ricans in the country, with most blocks usually being around 85-90% Puerto Rican alone, with most of the remaining portion made up of Dominicans and African Americans. Increases in Latino immigration and migration have fueled the growth of El Centro de Oro in Fairhill.
