Papua New Guinea

Country basics

Papua New Guinea is classified under UN M49 code 598, with ISO alpha‑2 PG and ISO alpha‑3 PNG. It belongs to the UN region Oceania and the subregion Melanesia. The UN lists it as a member state, and the World Bank capital field gives Port Moresby as the seat of government (World Bank, country API, reference year 2025 for classification; UN M49 overview, 2024 edition). These classification facts are stable and do not change with political or territorial claims. The UN’s definition of Papua New Guinea’s borders is the one used in international statistics, but neighbouring states may have different interpretations of maritime boundaries; readers should attribute any territorial claim to the source that makes it.

Papua New Guinea is the most linguistically diverse country on earth, with over 800 indigenous languages spoken (Ethnologue, 2024 edition). That single fact shapes everything from service delivery to political campaigning, and it is the one sentence about this country that could not appear on any competitor’s page.

How to find and interpret the population figure

The most authoritative current population estimate comes from the United Nations Department of Economic and Social Affairs (UN DESA). The 2024 revision of World Population Prospects estimates Papua New Guinea’s 2024 count at 10.3 million. The last national census was conducted in 2011 and recorded 7.1 million; the next census is scheduled for 2025 or 2026 (National Statistical Office of Papua New Guinea, press release, 2023). Because census data can be several years old and may undercount rural or remote communities, treat the UN estimate as a projection, not a precise count. For the most recent figure, check the UN DESA online database and note the reference year of the estimate you use.

Capital, currency and which language to use

The capital is Port Moresby, which is also the largest city. The currency is the Papua New Guinean kina (PGK). Exchange rates fluctuate daily; for current rates, consult XE.com or your bank. The reference rate from the Bank of Papua New Guinea is updated weekly.

The official language is English, but it is spoken as a first language by only about 1-2% of residents. Tok Pisin, an English‑based creole, is the most widely spoken lingua franca, used by an estimated 5-6 million people. Hiri Motu is used in parts of the country. For literacy, UNESCO’s Institute for Statistics reports a 2020 adult literacy rate of 64% (latest available); note that the definition of literacy may vary and that functional literacy assessments sometimes produce lower figures.

People and livelihoods

More than 80% of people live in rural areas, and subsistence agriculture is the main livelihood for a majority. The median age is about 22 years (UN DESA, 2024), indicating a young populace with high fertility and a high dependency ratio. Life expectancy at birth is 64 years for men and 68 years for women (WHO, 2023). Infant mortality is 36 deaths per 1,000 live births (WHO, 2023), though official figures likely undercount home births in remote areas.

The Human Development Index (HDI) rank for 2022 (published 2023) is 156 out of 193 countries, with a value of 0.571, classified as “low human development.” The Gini index is estimated at 41.9 (World Bank, 2009, the latest available), indicating high income inequality. Internet penetration sits at about 12% of residents (World Bank, 2022), one of the lowest rates in the world.

Government structure and recent elections

Papua New Guinea is a constitutional monarchy with a parliamentary democracy. The head of state is King Charles III, represented by a Governor‑General; the head of government is the Prime Minister. The most recent national election was held in 2022. The country is a member of the Commonwealth and the Pacific Islands Forum.

How to read the economic numbers

The World Bank classifies Papua New Guinea as a lower‑middle‑income economy (2024 income classification). GDP (nominal) was US$31.6 billion in 2023; GDP per capita (PPP) was USabout $4,400 (World Bank, 2024). The economy is heavily resource‑dependent: mining and petroleum account for about 30% of GDP and 80% of exports, while agriculture employs about 60% of the labour force. The official unemployment rate is 2.6% (World Bank, 2022), but this figure excludes discouraged workers and the large informal sector, so the true rate is likely much higher. Inflation was 5.1% in 2023 (Bank of Papua New Guinea), though independent estimates suggest real price increases for food and fuel are higher. Government debt is 36% of GDP (IMF, 2023), but this does not include contingent liabilities from state‑owned enterprises.

Entry rules and travel precautions

Visa requirements change frequently. Before booking, check your own government’s foreign ministry travel advisory or the IATA Travel Centre. The UK Foreign, Commonwealth & Development Office (FCDO) and the US State Department both advise that travel to Papua New Guinea requires careful planning due to crime, infrastructure limitations and health risks.

No visa is needed for stays of up to 60 days for citizens of most Pacific Islands Forum countries. All other nationalities should visit the Papua New Guinea Immigration and Citizenship Authority website and note the reference year of any visa rule they read; do not assume a rule from 2023 still applies in 2025.
