This graph describes the population of Muslim-majority countries by age. According to the 
graph the percentage aged 0-14 from 1990-2030 should significantly, and continually, decrease. 
However, the remaining age groups will continue to rise, with the exception of the 15-29 group, 
which is expected to decrease again around by 2030.
