Christianity goes global as world's largest religion

By Richard Allen Greene, CNN

(CNN) - Christians are by far the largest religious group on the planet, and the religion has gone truly global over the past century, according to a new report out Monday, which finds some of the world's biggest Christian communities in surprising places.

Europe was the clear center of world Christianity one hundred years ago, but today the Americas are home to more than a third of all Christians. In fact, the United States has the world's largest Christian population, of more than 247 million, followed by Brazil and Mexico.

China also appears on the list of top 10 largest Christian populations - with an estimated 67 million Christians, it has more followers of the faith than any western European country.

There are nearly 2.2 billion Christians around the world, making up about one-third of the world's population - the same percentage as a century ago, according to the Pew Forum on Religion & Public Life.

Islam is the world's second largest religion, with about 1.6 billion followers worldwide, the Washington-based organization calculates. That's just under one-quarter of the estimated 2010 world population of 6.9 billion.

Sub-Saharan Africa has seen the biggest explosion in its Christian population in the past century, going from about 9 million Christians in 1910 to about 516 million today - nearly a quarter of all the world's Christians. Three of the world's ten largest Christian populations are in Africa: Nigeria, the Democratic Republic of Congo and Ethiopia.

The study, "Global Christianity," is based on demographic and opinion data from 232 countries and territories. It's part of the Pew-Templeton Global Religious Futures Project, which has also included reports on the current and projected number of Muslims in the world.

It does not measure practice or belief, merely counting as Christian anyone who says they are.

The report calculates that half the world's Christians are Catholic, 37% are Protestants, and 12% are Orthodox. The remaining 1 percent belong to other traditions such as Mormonism.

    please change your name to librarians love Ayn Rand because republicans now belong to Christendom in America, also before you criticize study psychology because those that love themselves treat others with great respect and dignity everything starts and the individual not the collective

    Last time I checked Christianity was a group of different religions. Catholicism, Protestant, Baptist, etc are religions.

      Christianity isn't a religion. It's a relationship with Jesus Christ.

      "A relationship with Jesus Christ" might be the buzz phrase in christian circles but that doesn't make it any less a religion.

      You call it a dog, I call it a poodle.

    IT TAKES JUST AS MUCH FAITH to say there is no God as it does to say there is one..

    That's a fact not an opinion.

      Another fallacy from christian apologetics.

      Sorry, given the evidence for any god the rational conclusion is that there is none.

      given the fact that you produced no such evidence further solidifies my point.

    His bones are well hidden. You will never know where they were hidden. That was the whole point of hiding them.

    Ultimately, I know He's alive because He wants me to (John 6:44).

    • Jesus hates you for being a liar

      And for being gay. He hates you. Go ahead and ask him. If he isn't speaking to you that means he hates you.

      So the question remains then, why and how do you think you "know", what you tell yourself you "know" ? The fact is the only way you "know" anything, is because of chemical reactions in your brain. Jeebus didn't cause any of those. They occur for the many reasons they do. And obviously, in this case, it is because you have decided to delude yourself, and ignore the science of neuro chemistry.

    Those who can't do–preach. Religion is always sticking its ugly tentacles into everything. I'll take two working hands over 100 praying ones any day.

      There will be a new heaven and new earth, populated by those of us who love King Jesus during this life. Read the book of Revelation. Better still, repent and believe in God's risen Son while you can.

      I would love to shove a burning spear down your patheticly stupid throat, flay you alive, and roll you in salt.
      But for some reason that's illegal. But NOT ACCORDING TO THE BIBLE! PREPARE TO DIE!!!

    The day is drawing nigh when all will be forced to acknowledge the true Creator of the universe – the Flying Spaghetti Monster. Woe to the nonbelievers! You will believe when He reveals Himself in His pastalicious glory – but alas, it will be too late!

  16. Religion is EVIL

    See why the world is so f***ed up? Religion. It sucks. It's everywhere. And it refuses to leave people alone.

    This is what Hindus have it.

    God has four types of customers. His first customer is Aethist. Second customer is someone who drools about God all the time and truely loves God. Third type is believing in God but whinning and blaming God for everything (most of us fit this category). The forth type is "Sanyaasi" who liberates himself by giving up everything in life "including GOD".

    I like the first and the last type, unless God takes care of Aethist, He is not qualified to be God.

    christians always have been and always will be the MINORITY! there is no god and even if there was...so what - the beliefs made up by mid-eastern men thousands of years ago are some of the stupidest things ever to be created by humans... grow a freakin' brain people and think for yourself oh and get over yourselves too - there is no heaven waiting for you for being a slave to an imaginary spirit in the sky...your life has no meaning, you're an accident and a fluke just like everything else on this planet!

      I'd rather live believing there's a God and die and find out He doesn't exist, than to live believing there is no God and die only to find out He's real. If the first scenario is true, then I would've neither lost nor gained anything because there was nothing to lose or gain in the first place, but...if the second scenario is true, then I (you) would've lost EVERYTHING. Sorry, but my life has meaning and I feel sorry for you that you feel that life is meaningless. You may call us a moron, but Psalms 14;1 says YOU"RE A FOOLl for denying the existence of God.

      God Bless You! I respect your beliefs and I am proud to be a Christian! Why such hate? Believe what you want and let it be....I believe in God and believe in something greater than all of us. Merry Christmas!

      hey Mike the genius
      When you die, your consciousness ends. You won't "find out" anything, because you will be dead. And don't quote babble verses to prove the babble. It's called "circular reasoning". You choose to live a deluded life. That's your problem.
