The people clusters where the task will nearly 3X by 2050

Earlier, I presented a list of the projected populations of people groups by 2050. The good folks at Joshua Project sent me a variation of the sheet with % AGR, which stirred me up with the question: what are the people group clusters where the remaining task is growing fastest? This is a simple calculation (pop. 2025 / pop. 2015, sort in descending order), yet very revealing. Below are the least-reached clusters this methodology projects to be the fastest growing. (The Fulani and Hausa are two stunning examples; I'm not sure they would actually reach 100 million-plus by 2050, but these projections do reflect the actual growth rates of the regions they are in.) This is the biggest reason I am such a proponent of movements: we need Gospel spread that is both sustainable and faster than the population growth!
