The city of Paris in France had an estimated gross domestic product of 757.6 billion Euros in 2021, the most of any European city. Paris was followed by the spanish capital, Madrid, which had a GDP of 237.5 billion Euros, and the Irish capital, Dublin at 230 billion Euros. Milan, in the prosperous north of Italy, had a GDP of 228.4 billion Euros, 65 billion euros larger than the Italian capital Rome, and was the largest non-capital city in terms of GDP in Europe. The engine of Europe Among European countries, Germany had by far the largest economy, with a gross domestic product of over 4.18 trillion Euros. The United Kingdom or France have been Europe's second largest economy since the 1980s, depending on the year, with forecasts suggesting France will overtake the UK going into the 2020s. Germany however, has been the biggest European economy for some time, with five cities (Munich, Berlin, Hamburg, Stuttgart and Frankfurt) among the 15 largest European cities by GDP. Europe's largest cities In 2023, Moscow was the largest european city, with a population of nearly 12.7 million. Paris was the largest city in western Europe, with a population of over 11 million, while London was Europe's third-largest city at 9.6 million inhabitants.

This statistic illustrates the number of billionaires in leading cities in the EMEA (Europe, the Middle East and Asia) region as of 2016. It can be seen that the number of billionaires in Moscow stood at a total of 71, making Moscow the city in the EMEA region with the most billionaires at that time. Although this is the case London was not far behind, ranking second with a total of 62 billionaires as of 2016.

This statistic presents the top three European cities for billionaires. The figures were collected from a top 15 cities global listing in which, as of 2018 only three European cities ranked. In that time, the number of European billionaires that lived in the capital of Russia, Moscow, fell from 85 in 2014 to 70 in 2018.

Gross domestic product (GDP) per capita is a measure of economic production, which takes the entire output of a national economy during a year and divides it by the population of that country. In the European Union, Luxembourg, Ireland, Denmark, the Netherlands, and Austria come out on top as the countries which produced the most per capita in 2023. Europe's richest countries benefit from multinational companies Many criticisms have been made of using GDP per capita as away to judge a country's economic wealth in recent years, as global capital flows have come to distort the statistics and to give a warped impression of different countries' wealth. This is most notably the case for Ireland and for Luxembourg, which while certainly high-income countries, have experienced dramatic booms in their GDP over the past two decades due to the accounting practices of the large multinational corporations which have their European headquarters in these member states, such as Facebook and Apple in Dublin, and Amazon in Luxembourg. Will the poorest countries converge towards the EU average? At the bottom of the list, two of the most recent member states of the EU, Romania and Bulgaria, come last in terms of GDP per capita. Whether these countries will be able to capitalize on their relatively low-wages to spur economic growth and experience the convergence towards the older member states of the union shown by countries such as Estonia, Czechia, and Lithuania, remains a pressing issue for these poorer member states.
