The population of Mongolia is projected to reach around 3 million by 2019, with fertility and mortality being the main factors influencing population size. The country has low population density and high mortality rates for infants and children. Fertility rates have declined since 1989, leading to changes in the age structure of the population. The labor force is expected to grow steadily until the early 2000s, after which growth will slow down. This growth will impact education levels, enrollment rates, and the availability of teachers and classrooms in the future.
