Mongolia Population Pyramid 2017
Mongolia in 2017
In 2017, Mongolia had a total population of 3,104,364 people. A decade earlier, in 2007, the population was 2,607,966; it has grown by 19.0% since.
The median age was 27.0 years, and for every 100 people of working age (15–64) there were 47.4 children under 15 and 6.1 people aged 65 or over. This is an expansive pyramid — each cohort of children is larger than the one above it, the signature of high birth rates and rapid growth.
