The majority of Hispanics in Pennsylvania are of Puerto Rican descent, having one of the largest and fastest-growing Puerto Rican populations in the country. Most of the remaining Hispanic population is made up of Mexicans and Dominicans. Most Hispanics are concentrated in Philadelphia, Lehigh Valley and South Central Pennsylvania. Pennsylvania's reported population of Hispanics, especially among the Black race, has markedly increased in recent years. The Hispanic population is greatest in Bethlehem, Allentown, Reading, Lancaster, York, and around Philadelphia. It is not clear how much of this change reflects a changing population and how much reflects increased willingness to self-identify minority status. As of 2010, it is estimated that about 85% of all Hispanics in Pennsylvania live within a radius of Philadelphia, with about 20% living within the city itself.
