In the 2011 census, Nepal's population was approximately 26 million people with a population growth rate of 1.35% and a median age of 21.6 years.
 In 2016, the female median age was approximately 25 years old and the male median age was approximately 22 years old.
 Only 4.4% of the population is estimated to be more than 65 years old, comprising 681,252 females and 597,628 males.

 In 2011, the Birth rate is estimated to be 22.17 births per 1,000 people with an infant mortality rate of 46 deaths per 1,000 live births.
 Compared to the infant mortality rate in 2006 of 48 deaths per 1000 live births, the 2011 IMR is a slight decrease within that 5 year period.
 Infant mortality rate in Nepal is higher in rural regions at 44 deaths per 1000 live births, whereas in urban regions the IMR is lower at 40 deaths per 1000 live births.
 This difference is due to a lack of delivery assistance services in rural communities compared to their urban counterparts who have better access to hospitals and neonatal clinics.
