Joshua Project offers two ways of viewing the same people group data:
This method counts a people group for each country it lives in and is called People Group In Country (PGIC). For example, the Bambara in Mali are considered a distinct people group. If the Bambara live in 12 countries they are counted as 12 people groups. Of the 16,436 people groups in country, 7,162 are considered unreached and 4,823 are frontier unreached.

This method counts a people group once regardless of how many countries they live in and is called People Group Across Countries (PGAC). For example, if the Bambara live in 12 countries they are counted as only one people group. Of the 10,422 people groups across countries, 4,486 are unreached and 3,218 are frontier unreached.
