Christianity is growing rapidly in the Global South, declining as a share of population in Europe and North America.
The fastest growing Christian population on earth. Nine million in 1910, over seven hundred million today. Projected 1.1 billion by 2050.
Significant growth in China, South Korea, Philippines, India. China may have one hundred to one hundred thirty million Christians.
Around ninety percent Christian. The composition is shifting rapidly from Catholic to Protestant and Pentecostal.
From ninety five percent in 1910 to around seventy three percent today. Church attendance much lower than nominal affiliation.
Around ninety percent in 1970 to about sixty eight percent today. The unaffiliated are the fastest growing group in the US and Canada.
A small but persistent Christian presence, around four percent. Ancient communities in Egypt, Lebanon, Iraq, and Syria face significant challenges.
Of 17,446 documented people groups worldwide, 7,407 (42.5 percent) are considered unreached. Less than two percent evangelical Christian and less than five percent total Christian adherents.
The area between ten and forty degrees north latitude, stretching from North Africa through the Middle East to East Asia, contains the highest concentration of unreached people groups on earth. This region includes most of the world's Muslim, Hindu, and Buddhist populations. An estimated 3.2 billion people in the 10/40 Window have limited or no access to the Christian gospel.
Countries of particular focus. India, China, Pakistan, Bangladesh, Nepal, Indonesia, Afghanistan, Iran, Iraq, Saudi Arabia, Yemen, North Korea, and the Central Asian republics.
