A megachurch is an American term for a church having 2,000 or more people in average weekend attendance. In 2010, the Hartford Institute's database listed more than 1,300 such Protestant churches in the United States; according to that data, approximately 50 churches on the list had average attendance exceeding 10,000, with the highest recorded at 47,000 in average attendance. On one weekend in November 2015, around one in ten Protestant churchgoers in the US, or about 5 million people, attended service in a megachurch. While 3,000 individual Catholic parishes (churches) have 2,000 or more attendants for an average Sunday Mass, these churches are not seen as part of the megachurch movement.
