About this dataset

The dataset includes data on Christianity, Islam, Judaism, Buddhism, Hinduism, Sikhism, Shintoism, Baha'i Faith, Taoism, Confucianism, Jainism and various other syncretic and animist religions. For each religion or denomination category, it provides both the total population count and the percentage representation in relation to the overall population.

Additionally, - Columns labeled with Population provide numeric values representing the total number of individuals belonging to a particular religion or denomination. - Columns labeled with Percent represent numerical values indicating the percentage of individuals belonging to a specific religion or denomination within a given population. - Columns that begin with ** indicate primary categories (e.g., Christianity), while columns that do not have this prefix refer to subcategories (e.g., Christianity - Roman Catholics).

In addition to providing precise data about specific religions or denominations globally throughout multiple years,this dataset also records information about geographical locations by including state or country names under StateNme.

This comprehensive dataset is valuable for researchers seeking information on global religious trends and can be used for analysis in fields such as sociology, anthropology studies cultural studies among others

In 2023, **** percent of Americans were unaffiliated with any religion. A further **** percent of Americans were White evangelical Protestants, and an additional **** percent were White mainline Protestants. Religious trends in the United States Although the United States is still home to the largest number of Christians worldwide, the nation has started to reflect a more diverse religious landscape in recent years. Americans now report a wide range of religious beliefs and backgrounds, in addition to an increasing number of people who are choosing to identify with no religion at all. Studies suggest that many Americans have left their previous religion to instead identify as atheist, agnostic, or nothing in particular, with many reasoning that they stopped believing in the religion's teachings, that they didn't approve of negative teachings or treatment of LGBTQ+ people, or that their family was never that religious growing up. Christian controversies Over the last few years, controversies linked to Christian denominations have plagued the nation, including reports of child sexual abuse by the Catholic Church, the Church of Jesus Christ of Latter-day Saints, and the Southern Baptist Convention. Christian churches have also been accused of supporting discriminatory actions against LGBTQ+ people and people belonging to other religious groups. In addition, there have been increasing concerns about Christian nationalism, the political ideology that asserts that America was founded to be a Christian nation. Although the majority of Americans still think that declaring the United States a Christian nation would go against the U.S. Constitution, studies found that most Republicans would be in favor of this change.

Roman Catholic is the most common religious affiliation in Colombia. In a survey carried out in 2023, nearly ** percent of Colombian respondents claimed to be of Catholic faith, whereas the second most chosen religion was Evangelism, with **** percent of the people interviewed. More than ** percent of respondents answered they had no religious affiliation. The advent of evangelicalism in Colombia and LAC The share of Catholics in Colombia is above the average in Latin America and the Caribbean, where about ** percent of adults identify as followers of Catholicism. Nevertheless, even if Colombia stood out historically as one of the countries with the largest share of Catholics in the region, their numbers have been dwindling considerably in the past few decades: in the year 2000, **** of Colombians identified as Catholics, over ** percent points more than two decades later. Meanwhile, Evangelism keeps gaining ground in both the country and the region. While merely *** percent of Colombians were evangelical in 1996, this share had grown almost five-fold by 2020, while atheists and agnostics passed from *** to **** in the same lapse of time. The whole of Latin America is experiencing a similar trend, with evangelists accounting for more than one fifth of the population in countries such as Guatemala, Costa Rica, and Brazil. The success of Evangelical Churches in Latin America is related, among other things, to the creation of social safety nets in poor communities, the rise of conservative political parties and movements, and more flexible standards for ordination.
Religiosity among young Colombians Interestingly, eastern religions such as Buddhism enjoy the same popularity as Evangelism and Protestantism among young Colombians. Religion seems to have a considerable impact on youngsters’ life. More than half of surveyed Colombians aged between 15 and 29 claimed that religious beliefs provided them with inner peace, while another **** and ** percent said that it helped them to quit drugs and gangs, respectively. Only *** percent of the respondents affirmed that religious beliefs had no influence on their lives. As for the religiosity of young Catholic Colombians, very few claimed to be very observant. Around ** percent considered themselves not very observant, while around a third classified as somewhat observant.

In 2023, 27.5 percent of Americans were unaffiliated with any religion. A further 13.4 percent of Americans were White evangelical Protestants, and an additional 13.3 percent were White mainline Protestants.

Historically, Portugal has been a country of Catholics. The 2021 census demonstrated that this trend has not been inverted, as over 80 percent of the population in Portugal identified as Catholic. Protestant or Evangelic believers accounted for more than two percent of the population, while Jehovah's Witnesses constituted one percent of residents. Among non-Christian faiths, Muslims were the most representative group, making up 0.42 percent of the population.

Religious but generally not practicing the faith

In the same year, Catholics numbered more than seven million people spread throughout the country, conquering the religious majority in the mainland and in the two autonomous regions. Citizens without religion totaled more than 1.2 million, which made of them the second most numerous religious group in Portugal. Young people presented the same religious trend, with young Catholics being the most representative group, followed by non-religious. Among youngsters, the attendance of religious events was mostly conducted occasionally, while a quarter did not participate in such proceedings at all.

The contribute of immigration to the growth of Evangelical Christianity

Despite being the minority, non-Catholic Christian and non-Christian faiths have been growing in Portugal. In 2011, Evangelical believers totaled 75.6 thousand, more than doubling ten years after. Such growth was partially motivated by the increase in Brazilian immigration, as more than 61 percent of new members of Evangelical churches in 2023 were of Brazilian origin. In fact, Brazil was the place of origin of almost 82 percent of all the immigrant Evangelical Christians residing in Portugal. However, more than a quarter of new Evangelical Christians were Portuguese, which shows that other religions, namely Christian Catholicism, have been losing members to Evangelical Catholicism.

Religious adherence varies widely between countries and regions across the globe. While in some countries, such as Bangladesh (majority-Muslim), Thailand (majority-Buddhist), and Nigeria (over 50 percent Muslim and 45 percent Christian), almost all people indicate that religion is important in their daily lives, in others such as Japan, Sweden, and Estonia, over three quarters of people do not believe that religion is important to them. Among countries with higher levels of religious adherence, there are some interesting cases. Predominantly Islamic countries, such as Bangladesh, Indonesia, and Saudi Arabia, tend to show high levels of religious adherence. Italy, the historical center of the Catholic Church, records much higher levels of religiosity than other Western European countries, such as France, Germany, or the UK. The United States has almost double the number of people saying they believe religion is important in their daily life than not important. While religious adherence has declined over the past half century in the U.S., waves of immigration from predominantly Catholic countries, as well as the cultural impact of Evangelical Protestantism in some areas has meant that it is still one of the most religious Western countries. Israel, in spite of being an officially Jewish state, records roughly half of respondents being religious. Another notable trend is the tendency of some post-communist countries to show lower levels of religiosity, likely a result of the policy of state atheism under communism - Russia, Belarus, and Estonia all come towards the least religious end of the list for this reason, although Poland, or former-Soviet states in the Caucuses and Central Asia show much higher levels of religious adherence.

Roman Catholic was the most common religion affiliation in Mexico in 2023. In a survey carried out that year, roughly **** percent of Mexican respondents claimed to be of catholic faith.

Based on the 2020 census, the majority of Filipino households were affiliated with the Roman Catholic religion, numbering about 86 million people. Meanwhile, there were roughly seven million Muslims in the country. The Philippines is one of the countries in the world with the highest population professing the Catholic faith, after Brazil and Mexico.

Based on the 2020 census, Region 5 or the Bicol Region registered the highest share of households who reported Roman Catholic as their religious affiliation at 93.5 percent. This was followed by Region 8 or Eastern Visayas with a share of 92.3 percent. In contrast, only five percent of households in BARMM were Roman Catholics. The Philippines is one of the countries in the world with the highest population professing the Catholic faith, after Brazil and Mexico.
