The city of Houston which historically was centered on Protestant Christianity, and a part of the Bible Belt, is now home to many different religions owing to its large ethnic diverse population. According to a 2014 study by the Pew Research Center, 73% of the population of the city identified themselves as Christians, with 50% professing attendance at a variety of churches that could be considered Protestant, and 19% professing Roman Catholic beliefs. while 20% claim no religious affiliation. The same study says that other religions (including Judaism, Buddhism, Islam, and Hinduism) collectively make up about 7% of the population. As of 2016, 46% of the Houston-area population was Protestant, 31% was Catholic, 5% was of other religions, and 18% was of no religion.
