Uganda is the only place on this list of countries where Muslim population will increase the most by 2050 in which Christians will have higher fertility rates than Muslims in the future. Islam is currently the second largest religion with 3.84 million followers, and their number will reach 13.37 million in 2050 when they will account for 11.5% of the total population. Throughout history, Muslims have been targeted by different guerillas and terrorist groups, some of which have been affiliated with radical Islam. In the last two years, 12 Muslim clerics have been murdered, which has raised concerns among the community.
