Its 463 000 square kilometers of land area，a sea area of 3.12 million square kilometers and 600 separate islands make up one of the most diverse repositories of geographic，biological， linguistic and cultural wealth on earth. PNG has more than 5% of the world's biodiversity in less than 1% of the world's total land area. Population According to the 2000 Census，between 1980 and 2000 PNG's population grew by an annual average rate of 2.7% to 5.19 million. The Southern Highlands Province，followed by Western New Britain，recorded the highest population growth of 4.2% and 3.8% respectively.Approximately half of PNG's total population is under 19 years old. Most of the population lives in rural communities based on the traditional village structure and dependent on subsistence farming supplemented by cash cropping.Only 15－20% of Papua New Guineans live in the main urban areas of Port Moresby，Lae，Madang，Mt Hagan and Goroka. Economy PNG has a relatively small dual economy，comprising a formal and informal economy.The formal economy is dominated by large － scale resource projects ， particularly in mining and petroleum，and provides a large proportion of government revenue. The informal economy supports 85% of the people through semi － subsistence agriculture.The formal sector employs around 15% of the workforce. PNG has an abundance of natural resources including： Large reserves of minerals Extensive forestry and fishery assets Significant potential for agricultural expansion Many beautiful locations with potential for ecological and cultural tourism. Despite the potential of these resources，PNG's economic performance has fallen short of expectations.Economic growth has not kept up with population growth and performance varies considerably from year to year. During 2004，PNG's ec onomy grew because of buoyant commodity prices and good fiscal management by government.Increased foreign reserves and a strengthened Kina helped inflation and interest rates remain low.With moderate GDP growth ， rising tax receipts and reduced government borrowing costs，the PNG Government's fiscal deficit is expected to remain small， despite a modest surplus in 2004. However，with weak medium term revenue prospects，PNG needs to consolidate and build on current economic and fiscal progress and provide social services and a regulatory framework to support broad based economic growth.PNG needs improved accountability and governance mechanisms，including public expenditure management and public sector reform，to promote and safeguard improved productivity. With mining and petroleum sector production forecast to decline from 2006 ， major challenges for the PNG Government include making good use of existing revenue，expanding the non － mining sector and ensuring economic stability through continued political and social reforms. Social indicators PNG's population has suffered significant declines in living standards in recent years due to worsening economic performance.Although the country does not exhibit the widespread abject poverty present in some developing countries，poor health and social indicators show that poverty is a real problem. PNG's main social indicators，such as life expectancy and maternal and child mortality rates， show improvements since 1975，but are still well below the averages for lower middle income countries(LMICs)． PNG still has limited primary health care.Infectious diseases are claiming many lives，and there are serious public health risks from endemic diseases such a s malaria，and an emerging HIV/AIDS epidemic.An estimated 1.7% of people in PNG carry the virus. In education，the rate of participation in primary schooling is improving，but it remains lower than in most other countries in the region.

Here are some concrete examples of what MSF does： 256 for a medical kit.Thanks to the emergency medical kit，MSF is able to be operational 24 H in any country in the world.For example the “basic” medical kit allows MSF to treat 1000 people for 3 month.It is meant for the dispensary and consists of all essential medicins，bandages and products to disinfect along with standard medical equipment. 24 to treat a cholera patient.The MSF “Cholera” kit allows MSF to face an imminent cholera epidemic.It contains 4000 L of drips，antibiotics，plastified cover sheets，soap，disinfectant and chlorinated water as well as gloves for the nursing staff.The kit is meant to treat 625 patients and costs 14.876 or 24 per person. 179 to transport 100 kilograms of medicins.In 2000 ， MSF moved 1.548 tonnes of medicines，medical and logistic equipment to 35 countries.Of course costs differ from destination to destination and from type of transport to type of transport but over half of the goods a re transported by plane，a quarter by boat and the rest by road. 92 to vaccinate 100 children.The MSF “vaccination” kited is adapted to treat 10.000 people.It contains refrigerators and coldpacks to ensure that the vaccins remain cold，single use needles，vaccins and medical equipment needed for 5 teams of vaccinators.All this for a total cost of 9.231.75.
