The economy of Poland is an emerging and developing, high-income, industrialized, mixed economy that serves as the sixth-largest in the European Union by nominal GDP and fifth-largest by GDP (PPP). Poland boasts the extensive public services characteristic of most developed economies and is one of few countries in Europe to provide no tuition fees for undergraduate and postgraduate education and with universal public healthcare that is free at a point of use. Since 1988, Poland has pursued a policy of economic liberalisation but retained an advanced public welfare system. It ranks 20th worldwide in terms of GDP (PPP), 21st in terms of GDP (nominal), and 21st in the 2023 Economic Complexity Index. Among OECD nations, Poland has a highly efficient and strong social security system; social expenditure stood at roughly 22.7% of GDP.
The Visegrád Group is a cultural and political alliance of four Central European countries: the Czech Republic, Hungary, Poland, and Slovakia. The alliance aims to advance co-operation in military, economic, cultural and energy affairs, and to further their integration with the EU. All four states are also members of the European Union (EU), the North Atlantic Treaty Organization (NATO), and the Bucharest Nine (B9).
A voivodeship is the highest-level administrative division of Poland, corresponding to a province in many other countries. The term has been in use since the 14th century and is commonly translated into English as "province".
A developed country, or advanced country, is a sovereign state that has a high quality of life, developed economy, and advanced technological infrastructure relative to other less industrialized nations. Most commonly, the criteria for evaluating the degree of economic development are the gross domestic product (GDP), gross national product (GNP), the per capita income, level of industrialization, amount of widespread infrastructure and general standard of living. Which criteria are to be used and which countries can be classified as being developed are subjects of debate. Different definitions of developed countries are provided by the International Monetary Fund and the World Bank; moreover, HDI ranking is used to reflect the composite index of life expectancy, education, and income per capita. In 2023, 40 countries fit all four criteria, while an additional 19 countries fit three out of four.
The Human Development Index (HDI) is a statistical composite index of life expectancy, education, and per capita income indicators, which is used to rank countries into four tiers of human development. A country scores a higher level of HDI when the lifespan is higher, the education level is higher, and the gross national income GNI (PPP) per capita is higher. It was developed by Pakistani economist Mahbub ul-Haq and was further used to measure a country's development by the United Nations Development Programme (UNDP)'s Human Development Report Office.
