New York City, one of the three U.S. cities Pope Francis will visit this week, is in a three-way tie as the most Catholic city in the United States, a religious institute's analysis found.
In Boston, New York and Pittsburgh, 36 percent of residents said they were Catholic, according to the Public Religion Research Institute's (PRRI) 2014 study, which ranked the largest religious groups in 30 major U.S. metropolitan areas -- those with populations of at least 50,000.
Philadelphia, where the pope plans to hold an outdoor Mass at which up to 2 million people are expected on September 27, and Chicago tie as the second-most Catholic city in the U.S., with 33 percent.
Washington, D.C., where Francis will canonize Junipero Serra on September 23 and address a joint session of the U.S. Congress on September 24, is in a three-way tie for 11th place, with 19 percent of residents who say they are Catholic.
In its study released in August, PRRI found Catholics, the religiously unaffiliated and Protestants are the top three religious groups, respectively, in the major metro areas.
It also found Rhode Island is the most Catholic state, with 44 percent of its population identifying with the church.
