Pew Research Center in the context of "Non-denominational Muslims"

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.

In 2020, 85.84% of the population in Georgia adhered to Christianity (mainly Georgian Orthodox), 11% were Muslim, 0.1% were Jewish, 0.04% were Baháʼí and 3% had no religious beliefs. Other religious groups include Jehovah's Witnesses and Yazidis. Orthodox churches serving other non-Georgian ethnic groups, such as Russians and Greeks, are subordinate to the Georgian Orthodox Church.

A Pew Research Center study about religion and education around the world in 2016, found that between the various Christian communities, Georgia ranks as the third highest nation in terms of Christians who obtain a university degree in institutions of higher education (57%).

A Christian (/ˈkrɪstʃən, -tiən/ ) is a person who follows or adheres to Christianity, a monotheistic Abrahamic religion based on the life and teachings of Jesus Christ. Christians form the largest religious community in the world. The words Christ and Christian derive from the Koine Greek title Christós (Χριστός), a translation of the Biblical Hebrew term mashiach (מָשִׁיחַ) (usually rendered as messiah in English). While there are diverse interpretations of Christianity which sometimes conflict, they are united in believing that Jesus has a unique significance. The term Christian used as an adjective is descriptive of anything associated with Christianity or Christian churches, or in a proverbial sense "all that is noble, and good, and Christ-like."

According to a 2011 Pew Research Center survey, there were 2.3 billion Christians around the world, up from about 600 million in 1910. Today, about 37% of all Christians live in the Americas, about 26% live in Europe, 24% live in sub-Saharan Africa, about 13% live in Asia and the Pacific, and 1% live in the Middle East and North Africa. Christians make up the majority of the population in 158 countries and territories. 280 million Christians live as a minority. About half of all Christians worldwide are Catholic, while more than a third are Protestant (37%). Eastern Christians, including the Eastern Orthodox, Oriental Orthodox, and Church of the East, comprise 12% of the world's Christians. Other Christian groups make up the remainder. By 2050, the Christian population is expected to exceed 3 billion due to overall total fertility rate according to Pew Research Center. According to a 2012 Pew Research Center survey, Christianity will remain the world's largest religion in 2050, if current trends continue. In recent history, Christians have experienced persecution of varying severity, especially in the Middle-East, North Africa, East Asia, and South Asia.

According to a Pew estimation in 2025, Christians made up to 2.3 billion of the worldwide population of about 8 billion people. This represents nearly one-third of the world's population and is the largest religion in the world, with the three largest groups of Christians being the Catholic Church, Protestantism, and the Eastern Orthodox Church. The largest Christian denomination is the Catholic Church, with 1.3 billion baptized members. The second largest Christian branch is either Protestantism (if it is considered a single group), or the Eastern Orthodox Church (if Protestants are considered to be divided into multiple denominations).

According to a 2020 Pew Research Center study, of the then 201 countries and territories, 120 had Christian majorities, four fewer than in the 2010 study.

Adherents of Islam constitute the world's second largest and fastest growing major religious grouping, maintaining suggested 2017 projections in 2022. As of 2020, Pew Research Center (PEW) projections suggest there are a total of 2 billion adherents worldwide. Further studies indicate that the global spread and percentage growth of Islam is primarily due to relatively high birth rates and a youthful age structure. Conversion to Islam has no impact on the overall growth of the Muslim population, as the number of people converting to Islam is roughly equal to the number of those leaving the faith.

Most Muslims fall under either of three main branches:

New York City has been called the media capital of the world. The media organizations based in New York City are internationally influential and include some of the most important newspapers, largest publishing houses, biggest record companies, and most prolific television studios in the world. It is a major global center for the book, magazine, music, newspaper, and television industries. A 2019 Pew Research Center report found that 12 percent of all U.S. newsroom employees live in New York City, disproportionately higher than the 7 percent of the U.S. working-age population that lives in New York City.

New York is also the largest media market in North America (followed by Los Angeles, Chicago, and Toronto). Some of the city's media conglomerates include CNN (CNN Global), the Hearst Corporation, NBCUniversal, The New York Times Company, the Fox Corporation and News Corp, the Thomson Reuters Corporation, and Warner Bros. Discovery. Seven of the world's top eight global advertising agency networks are headquartered in New York. Three of the "Big Four" record labels are also headquartered or co-headquartered in the city. One-third of all American independent films are produced in New York. More than 200 newspapers and 350 consumer magazines have an office in the city and the book-publishing industry employs about 25,000 people.

In folklore, a ghost is the soul or spirit of a dead person or non-human animal that is believed by some people to be able to appear to the living. In ghostlore, descriptions of ghosts vary widely, from an invisible presence to translucent or barely visible wispy shapes to realistic, lifelike forms. The deliberate attempt to contact the spirit of a deceased person is known as necromancy, or in spiritism as a séance. Other terms associated with it are apparition, haunt, haint, phantom, poltergeist, shade, specter, spirit, spook, wraith, demon, and ghoul.

The belief in the existence of an afterlife, as well as manifestations of the spirits of the dead, is widespread, dating back to animism or ancestor worship in pre-literate cultures. Certain religious practices—funeral rites, exorcisms, and some practices of spiritualism and ritual magic—are specifically designed to rest the spirits of the dead. Ghosts are generally described as solitary, human-like essences, though stories of ghostly armies and the ghosts of animals other than humans have also been recounted. They are believed to haunt particular locations, objects, or people they were associated with in life. According to a 2009 study by the Pew Research Center, 18% of Americans say they have seen a ghost.
