Important: These are model inputs, not a measured city age profile. Country-level birth, death and life-expectancy values are applied to the city baseline because city-level vital statistics are not available consistently for every location in this dataset.
The imported city population is the baseline observation used by this page. We do not present reconstructed historical city populations as observed facts because applying today's national birth/death rates backward would not account for migration, boundary changes or historical rate changes.
If current national birth and death rates stayed constant and migration were ignored, the model would produce 342,191 by 2030, 413,057 by 2040, and 498,599 by 2050. This is a scenario calculation, not an official forecast. It assumes constant rates and excludes migration, boundary changes, policy and economic shifts.
Port Moresby is a medium-sized city located in Papua New Guinea. With an estimated population of 317,374 people, it represents a significant urban center within the country. The city operates in the Pacific/Bougainville time zone (UTC+11:00), placing it among the cities that share this temporal region.
Demographically, Port Moresby has a growing natural-change estimate. With a birth rate of 26 and a death rate of 7 per 1,000 residents annually, the population is rapidly growing. The average life expectancy stands at 65.0 years, reflecting the overall health and living conditions in the region. The model estimates approximately 8,252 births and 2,222 deaths per year, resulting in a net change of 6,030 people per year.
The live counters on this page provide continuously updated estimates based on these annual rates, calculating births, deaths, and population changes from our baseline data date of 2026-05-20. These figures offer valuable insights into the demographic dynamics of Port Moresby and its position within Papua New Guinea's urban landscape.
