Affinity Groups Around
In a world with dissolving borders, global
“affinity groups”—large groupings of related
peoples that share similar origins, languages
and cultures—act as a lens through which
missionaries view lostness and focus strategy to
share the gospel.
Focusing strategy through affinity groups gives
missionaries a more complete picture of the
people they are working to reach as well as the
freedom to pursue the lost regardless of their
IMB has identified eight primary affinity groups

Explore People Groups in Google Earth
Google Earth lets you explore the entire globe
right from your computer. You can view a variety
of geographic data available in KML format.
Global Research produces KML data sets
highlighting Unengaged, Unreached People Groups
with populations over 100,000 (UUPG100k). We’re
also developing KML data that shows locations
for all People Groups around the world. It’s
part of the People Group Mapping Project (PGMP).

Light of the World
All followers of Christ are called to be the

Points of light represent evangelicals. Points
of darkness represent the absence of
evangelicals. To learn more about how you can
