A Christian is a person who adheres to Christianity, an Abrahamic, monotheistic religion based on the life and teachings of Jesus Christ. "Christian" derives from the Koine Greek word Christůs (???????), a translation of the Biblical Hebrew term mashiach.
While there are diverse interpretations of Christianity which sometimes conflict, they are united in believing that Jesus has a unique significance. The term "Christian" is used adjectivally to describe anything associated with Christianity, or in a proverbial sense "all that is noble, and good, and Christ-like."
According to a 2011 Pew Research Center survey, there were 2.2 billion Christians around the world in 2010, up from about 600 million in 1910. By 2050, the Christian population is expected to exceed 3 billion. According to a 2012 Pew Research Center survey Christianity will remain the world's largest religion in 2050, if current trends continue.
Today, about 37% of all Christians live in the Americas, and about 26% live in Europe, 24% of total Christians live in sub-Saharan Africa, about 13% in Asia and the Pacific, and 1% of the world's Christians live in the Middle east and North Africa. About half of all Christians worldwide are Catholic, while more than a third are Protestant (37%).Orthodox communions comprise 12% of the world's Christians.
