Papua New Guinea's soaring youth population is expected to reach 21 million by 2050.
At independence in 1975 the PNG population was just over 3 million, the current population is about 12.9 million people.
This dramatic growth poses significant issues for PNG but the United Nations Population Fund believes it can bring a 'demographic dividend' to the country if the right investments are made in family planning, education and employment.
