Map Showing the Spread of Christianity Between 33 & 2000AD

Map created by reddit user PanzerMan1002The map above shows the spread of Christianity around the world and when various areas likely became majority Christian, even if they subsequently no longer are (e.g. North Africa, Turkey and the Middle East).

And the overall number of Christians in each century.

The source for the population numbers comes from:

“I Used ‘World Christian Trends, AD 30-AD 2200‘ by David B. Barrett and Todd M. Johnson, which you can find on Google Books, and some other online sources. I tried to use the lowest possible numbers available, so as to filter out more liberal adherent estimates from the early years.”

And as for Madagascar:

“As far as Madagascar is concerned, it’s really tricky to determine exact numbers. Christians in Madagascar often mix their practices with regional paganism, so it’s hard to tell where you draw the line between the two. U.S. Department of State cites a number of 41%, which seems reasonable.”

And Saint Thomas Christians in India?

“The map seeks to show areas that at one time or another were majority Christian. Although Kerala has a huge population of St. Thomas Christians, they never constituted a majority. I think today it’s about 11-15% there.”

Here are the numbers by century:

• 1st Century: 800,000
• 2nd Century: 4,660,000
• 3rd Century: 14,010,000
• 4th Century: 25,320,000
• 5th Century: 37,800,000
• 6th Century: 40,400,000
• 7th Century: 40,570,000
• 8th Century: 40,870,000
• 9th Century: 40,830,000
• 10th Century: 44,670,000
• 11th Century: 51,960,000
• 12th Century: 65,710,000
• 13th Century: 83,910,000
• 14th Century: 56,730,000
• 15th Century: 75,890,000
• 16th Century: 100,440,000
