Human Development Index in the context of "Newar people"

Oceania (UK: /ˌoʊsiˈɑːniə, ˌoʊʃi-, -ˈeɪn-/ OH-s(h)ee-AH-nee-ə, -⁠AY-, US: /ˌoʊʃiˈæniə, -ˈɑːn-/ OH-shee-A(H)N-ee-ə) is a geographical region including Australasia, Melanesia, Micronesia, and Polynesia. Outside of the English-speaking world, Oceania is generally considered a continent, while Mainland Australia is regarded as its continental landmass. Spanning the Eastern and Western hemispheres, at the centre of the water hemisphere, Oceania is estimated to have a land area of about 9,000,000 square kilometres (3,500,000 sq mi) and a population of around 46.3 million as of 2024. Oceania is the smallest continent in land area and the second-least populated after Antarctica.

Oceania has a diverse mix of economies from the highly developed and globally competitive financial markets of Australia, French Polynesia, Hawaii, New Caledonia, and New Zealand, which rank high in quality of life and Human Development Index, to the much less developed economies of Kiribati, Papua New Guinea, Tuvalu, Vanuatu, and Western New Guinea. The largest and most populous country in Oceania is Australia, and the largest city is Sydney. Puncak Jaya in Indonesia is the highest peak in Oceania at 4,884 m (16,024 ft).

The Organisation for Economic Co-operation and Development (OECD; French: Organisation de coopération et de développement économiques, OCDE) is an intergovernmental organisation with 38 member countries, founded in 1961 to stimulate economic progress and world trade. It is a forum whose member countries describe themselves as committed to democracy and the market economy, providing a platform to compare policy experiences, seek answers to common problems, identify good practices, and coordinate domestic and international policies of its members.

The majority of OECD members are generally regarded as developed countries, with high-income economies, and a very high Human Development Index.

The population of Africa has grown rapidly over the past century and consequently shows a large youth bulge, further reinforced by a low life expectancy of below 50 years in some African countries. Total population as of 2017 is estimated at more than 1.25 billion, with a growth rate of more than 2.5% p.a. The most populous African country is Nigeria with 191 million inhabitants as of 2017 and a growth rate of 2.6% p.a.

A developing country is a country with a less-developed industrial base and a lower Human Development Index (HDI) relative to developed countries. However, this definition is not universally agreed upon. There is also no clear agreement on which countries fit this category. The terms low-and middle-income country (LMIC) and newly emerging economy (NEE) are often used interchangeably but they refer only to the economy of the countries. The World Bank classifies the world's economies into four groups, based on gross national income per capita: high-, upper-middle-, lower-middle-, and low-income countries. Least developed countries, landlocked developing countries, and small island developing states are all sub-groupings of developing countries. Countries on the other end of the spectrum are usually referred to as high-income countries or developed countries.

There are controversies over the terms' use, as some feel that it perpetuates an outdated concept of "us" and "them". In 2015, the World Bank declared that the "developing/developed world categorization" had become less relevant and that they would phase out the use of that descriptor. Instead, their reports will present data aggregations for regions and income groups. The term "Global South" is used by some as an alternative term to developing countries.

Jakarta, officially the Special Capital Region of Jakarta, is the capital and largest city of Indonesia and an autonomous region at the provincial level. Lying on the northwest coast of Java, the world's most populous island, Jakarta is the largest metropole in Southeast Asia and serves as the Headquarters of ASEAN. The Special Region has a status equivalent to that of a province and is bordered by the province of West Java to the south and east and Banten to the west. Its coastline faces the Java Sea to the north, and it shares a maritime border with Lampung to the west. Jakarta's metropolitan area has an estimated population of 41.9 million as of 2025, making it the largest urban area in Indonesia and the world; in addition of being ASEAN's second largest economy after Singapore.

Jakarta is the economic, cultural, and political centre of Indonesia. Although Jakarta extends over only 661.23 km (255.30 sq mi) and thus has the smallest area of any Indonesian province, its metropolitan area covers 7,076.31 km (2,732.18 sq mi), which includes the satellite cities of Bogor, Depok, Tangerang, South Tangerang, and Bekasi. Jakarta ranks first among the Indonesian provinces in the human development index. Jakarta's business and employment opportunities, along with its ability to offer a potentially higher standard of living compared to other parts of the country, have attracted migrants from across the Indonesian archipelago, making it a melting pot of numerous cultures.

The Baltic states or the Baltic countries is a geopolitical term encompassing Estonia, Latvia, and Lithuania. All three countries are members of NATO, the European Union, the Eurozone, and the OECD. The three sovereign states on the eastern coast of the Baltic Sea are sometimes referred to as the "Baltic nations", less often and in historical circumstances also as the "Baltic republics", the "Baltic lands", or simply the Baltics.

All three Baltic countries are classified as high-income economies by the World Bank and maintain a very high Human Development Index. The three governments engage in intergovernmental and parliamentary cooperation. There is also frequent cooperation in foreign and security policy, defence, energy, and transportation.

The economy of Europe comprises about 748 million people in 50 countries. Throughout this article "Europe" and derivatives of the word are taken to include selected states whose territory is only partly in Europe, such as Turkey, Azerbaijan and Georgia, and states that are geographically in Asia, bordering Europe and culturally adherent to the continent, such as Armenia and Cyprus.

There are differences in wealth across Europe which can be seen roughly along the former Cold War divide, with some countries breaching the divide (Greece, Portugal, Slovenia, the Czech Republic, Lithuania, Latvia and Estonia). Whilst most European states have a GDP per capita higher than the world's average and are very highly developed, some European economies, despite their position over the world's average in the Human Development Index, are relatively poor. Europe has total banking assets of more than $50 trillion; the United Kingdom accounts for 25% ($12 trillion) of Europe’s total banking assets followed by France with 20% ($10 trillion) and Germany with 15% ($7 trillion). Europe Global assets under management is more than $20 trillion, with the United Kingdom accounting for more than 40% ($8 trillion) of Europe’s total AUM followed by France with 20% ($4 trillion) and Germany with 12% ($2 trillion). London and Paris are by far the economically strongest cities in Europe, each with a GDP exceeding $1 trillion. London and Paris are major economic hubs in Europe, with the London Stock Exchange and Euronext Paris, the two largest stock exchanges in Europe by market cap.

Developmental psychology is the scientific study of how and why humans grow, change, and adapt across the course of their lives. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, aging, and the entire lifespan. Developmental psychologists aim to explain how thinking, feeling, and behaviors change throughout life. This field examines change across three major dimensions, which are physical development, cognitive development, and social emotional development. Within these three dimensions are a broad range of topics including motor skills, executive functions, moral understanding, language acquisition, social change, personality, emotional development, self-concept, and identity formation.

Developmental psychology explores the influence of both nature and nurture on human development, as well as the processes of change that occur across different contexts over time. Many researchers are interested in the interactions among personal characteristics, the individual's behavior, and environmental factors, including the social context and the built environment. Ongoing debates in regards to developmental psychology include biological essentialism vs. neuroplasticity and stages of development vs. dynamic systems of development. While research in developmental psychology has certain limitations, ongoing studies aim to understand how life stage transitions and biological factors influence human behavior and development.
