Total Population in 10/40: 4.89 billion people

Total People Groups in 10/40: 8,213 people groups

Total UPG’s in 10/40: 5,626 Unreached People Groups totaling 3.05 billion people. 40% of all individuals

60% of unreached people groups live in countries closed to missionaries from North America.

Over 1,000 unreached people groups are NOT in the 10/40 Window, these total over 80 million individuals.

Open Doors Report


Annual Income of all Church Members: $42 trillion.  [1]

  • (Annual income of Evangelical Christians is approximately $7 trillion.)


Given to any Christian causes: $700 billion. [1]

Americans have recently spent more money buying Halloween costumes for their pets than the amount given to reach the unreached.
  • That's also how much we spend in America on Christmas.

Given to Missions: $45 billion

  • That's only 6.4% of the money given to Christian causes of any kind (2015). [1]  *5.6% reported in 2010, GAC [2]
  • That's also how much we spend in America on dieting programs.
  • Embezzled:  If you are doing the math and realize there is $50 billion missing, this is where it went. [1]


  • Pastoral ministries of local churches (mostly in Christian nations):  $677 billion (96.8%) [2]
  • "Home Missions" in same Christian nations:  $20.3 billion (2.9%) [2]
  • Going to Unevangelized Non-Christian world: $2.1 billion (.3%) [2]  *This is different than "Unreached"
  • Money that goes toward Unreached Peoples: *Estimated $450 million [3]

[3] *In 2001 only 1% of giving to "Missions" went to unreached - if that trend holds true today it would be $450 million.  The estimated $450 million going toward UPG's is only .001% of the $42 trillion Income of Christians.  For every $100,000 that Christians make, they give $1 to the unreached.


  • Evangelical Christians could provide all of the funds needed to plant a church in each of the 6,900 unreached people groups with only 0.03% of their income.
  • The Church has roughly 3,000 times the financial resources and 9,000 times the manpower needed to finish the Great
  • Commission.If every evangelical gave 10% of their income to missions we could easily support 2 million new missionaries.

Is God to blame for not "Calling" People to Missions?

If everyone is obeying God’s “calling” to be a missionary wherever they are then God is calling 99.9995% of people to work among the 44.3% of the world population that already has the gospel, and calling virtually no one (.0005%) to relocate among the other 55.7% of the world population that are not Christian. You have a better chance of being in a plane crash than being one of the few missionaries to the unreached out of the total 2 billion Christians in the world.

In light of God’s word, this seems unfathomable and it appears to be almost complete disobedience on the part of the Church worldwide to go make disciples of all the nations. Financially we are hoarding 99.99% of our income to ourselves and what little is given is mostly directed toward reached people groups.

The current status quo is to do virtually nothing to reach the UPG’s of the world. The percentages of man-power and money focused on UPG’s are almost undetectable they are so small. The amount of resources that fall off the Christian table for unreached peoples is more comparable (I Googled it…) with the number of skin cells you lose over a month’s time: something hardly worth calling a sacrifice of the body.
