Demographics of Europe in the context of "European Christians"

Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the Turkish straits.

Europe covers approx. 10,186,000 square kilometres (3,933,000 sq mi), or 2% of Earth's surface (6.8% of Earth's land area), making it the second-smallest continent (using the seven-continent model). Politically, Europe is divided into about fifty sovereign states, of which Russia is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a total population of about 745 million (about 10% of the world population) in 2021; the third-largest after Asia and Africa. The European climate is affected by warm Atlantic currents, such as the Gulf Stream, which produce a temperate climate, tempering winters and summers, on much of the continent. Further from the sea, seasonal differences are more noticeable producing more continental climates.

Christianity is the predominant religion in Europe. Christianity has been practiced in Europe since the first century, and a number of the Pauline Epistles were addressed to Christians living in Greece, as well as other parts of the Roman Empire.

According to a 2010 study by the Pew Research Center, 76.2% of the European population identified themselves as Christians.

There are over 250 languages indigenous to Europe, and most belong to the Indo-European language family. Out of a total European population of 744 million as of 2018, some 94% are native speakers of an Indo-European language. The three largest phyla of the Indo-European language family in Europe are Romance, Germanic, and Slavic; they have more than 200 million speakers each, and together account for close to 90% of Europeans.

Smaller phyla of Indo-European found in Europe include Hellenic (Greek, c. 13 million), Baltic (c. 4.5 million), Albanian (c. 7.5 million), Celtic (c. 4 million), and Armenian (c. 4 million). Indo-Aryan, though a large subfamily of Indo-European, has a relatively small number of languages in Europe, and a small number of speakers (Romani, c. 1.5 million). However, a number of Indo-Aryan languages not native to Europe are spoken in Europe today.

Population decline, also known as depopulation, is a reduction in a human population size. Throughout history, Earth's total human population has continued to grow, but projections suggest this long-term trend may be coming to an end. From antiquity (10th century BCE–500 CE) until the beginning of the Industrial Revolution in early modern Europe (late 18th–early 19th centuries), the global population grew very slowly, at about 0.04% per year. After about 1800 the growth rate accelerated to a peak of 2.1% annually during the mid-20th-century baby boom (1945–1968 period), but since then, due to the worldwide collapse of the total fertility rate, it has slowed to 0.9% as of 2023. The global growth rate in absolute numbers accelerated to a peak of 92.8 million in 1990, but has since slowed to 70.4 million in 2023.

Long-term projections indicate that the growth rate of the human population on the planet will continue to slow down, and that before the end of the 21st century it will reach growth zero. Examples of this emerging trend are Japan, whose population is currently (2023) declining at the rate of 0.5% per year, and China, whose population has peaked and is currently (2023) declining at the rate of about 0.2% per year. By 2050, Europe's population is projected to be declining at the rate of 0.3% per year. Population growth has declined mainly due to the abrupt decline in the global total fertility rate, from 5.3 in 1963 to 2.2 in 2023. The decline in the total fertility rate has occurred in every region of the world and is a result of a process known as demographic transition. To maintain its population, ignoring migration, a country on average requires a minimum fertility rate of 2.2 children per woman of childbearing age (the number is slightly greater than two because not all children live to adulthood). However, most societies experience a drop in fertility to well below two as they grow wealthier.

"European people" is an umbrella term for people who belong to any ethnic, racial, or national group with origins in Europe. Today, it primarily refers to people who are from Europe and reside in the continent, as well as the European diaspora. By extension, however, the term "European" may be applied to identify people in the context of demographics in certain countries outside of Europe—namely in the Americas and in Oceania—where people of European ancestry constitute the majority of the population while being part of a non-European national group. Additionally, any person who holds European Union citizenship may be identified as European in that particular context.

As of 2025, Europe's total population is estimated to be 744 million people, with nearly 87 million international migrants in 2020. Per a 2015 estimate, over 480 million people in countries outside of Europe have at least some European ancestry. Most indigenous Europeans are racially classified as White, which is also the most common term applied to people of European descent in non-European countries. Between the 18th and 20th centuries, a now-disproven race concept classified European people as part of the so-called Caucasian race, which broadly grouped together the populations of Europe, West Asia and North Africa, Central Asia, and South Asia. Although it is generally avoided in modern academic discourse, "Caucasian" is still used in official data for United States censuses to racially classify people whose ancestry or ethnicity is European, Middle Eastern, or North African.
