Christian population growth is the population growth of the global Christian community. According to a 2011 Pew Research Center survey, there were more than 2.2 billion Christians around the world in 2010, more than three times as many as the 600 million recorded in 1910. However, this rate of growth is slower than the overall population growth over the same time period.[1] In 2020, Pew estimated the number of Christians worldwide to be around 2.38 billion.[2] According to various scholars and sources, high birth rates and conversions in the Global South were cited as the reasons for the Christian population growth.[3][4][5][6][7][8] In 2023, it was reported: "There will be over 2.6 billion Christians worldwide by the middle of 2023 and around 3.3 billion by 2050, according to a report published in early January by the Center for the Study of Global ChristianityatGordon Conwell Theological Seminary."[9][10]
The Christian fertility rate is 2.7 children per woman, which is higher than the global average fertility rate of 2.5. Globally, Christians were only slightly older (median age of 30) than the global average median age of 28 in 2010. According to Pew Research religious switching is projected to have a modest impact on changes in the Christian population.[14] According to various scholars and sources, Pentecostalism is the fastest-growing religious movement in the world;[15][16][17][18][19] this growth is primarily due to religious conversion to Pentecostal and Charismatic Christianity.[20][21]
According to the World Christian Encyclopedia, approximately 2.7 million converting to Christianity from another religion, World Christian Encyclopedia also cited that Christianity rank at first place in net gains through religious conversion.[22] While according to "The Oxford Handbook of Religious Conversion", approximately 15.5 million converting to Christianity from another religion, while approximately 11.7 million leave Christianity, and most of them become irreligious, resulting in a net gain of 3.8 million.[23] Christianity earns about 65.1 million people due to factors such as birth rate and religious conversion while losing 27.4 million people due to factors such as death rate and religious apostasy. Most of the net growth in the numbers of Christians are in Africa, Latin America and Asia.[23]
The Christian fertility rate has varied throughout history. The Christian fertility rate also varies from country to country. In the 20-year period from 1989 to 2009, the average world fertility rate decreased from 3.50 to 2.58, a fall of 0.92 children per woman, or 26%. The weighted average fertility rate for Christian nations decreased in the same period from 3.26 to 2.58, a fall of 0.68 children per woman, or 21%. The weighted average fertility rate for Muslim nations decreased in the same period from 5.17 to 3.23, a fall of 1.94 children per woman, or 38%. While Muslims have an average of 3.1 children per woman—the highest rate of all religious groups—Christians are[when?] second, with 2.7 children per woman.[24]
The gap in fertility between the Christian- and Muslim-dominated nations fell from 67% in 1990 to 17% in 2010. According to a study published by the Pew Research Center in 2017, births to Muslims between the years of 2010 and 2015 made up an estimated 31% of all babies born around the world. By the Pew Research Center's estimates, the Muslim fertility rate and Christian fertility rate will converge by 2040.[25]
According to the World Christian Encyclopedia, approximately 2.7 million convert to Christianity annually from another religion; World Christian Encyclopedia also stated that Christianity ranks in first place in net gains through religious conversion.[22] While, according to book "The Oxford Handbook of Religious Conversion", which published by the professor of Christian mission Charles E. Farhadian,[27] and the professor of psychology Lewis Ray Rambo,[28] between 1990 and 2000, approximately 1.9 million people converted to Christianity from another religion, with Christianity ranking first in net gains through religious conversion.[29]
According to "The Oxford Handbook of Religious Conversion", in mid-2005 approximately 15.5 million converted to Christianity from another religion, approximately 11.7 million left Christianity, and most of them became irreligious, resulting in a net gain of 3.8 million.[23] Christianity added about 65.1 million people due to factors such as birth rate and religious conversion, while it lost 27.4 million people due to factors such as death rate and religious apostasy in mid-2005. Most of the net growth in the numbers of Christians is in Africa, Latin America and Asia.[23]
According to scholar Philip Jenkins Christianity was growing rapidly[weasel words] in China and some other Asian countries and sub-Saharan Africa around 2002.[30]
According to a 2012 report by the Singapore Management University, more people in Southeast Asia were converting to Christianity, and these new converts are mostly Chinese business managers.[33] Scholars Juliette Koning and Heidi Dahles of Vrije Universiteit Amsterdam stated that there was a "rapid expansion of charismatic Christianity from the 1980s onwards. Singapore, China, Hong Kong, Taiwan, Indonesia, and Malaysia were said to have the fastest-growing Christian communities and the majority of the new believers are "upwardly mobile, urban, middle-class Chinese". Asia has the second largest Pentecostal-charismatic Christians of any continent, with the number growing from 10 million to 135 million between 1970 and 2000".[33] According to scholar Wang Zuoa, 500,000 Chinese convert to Protestantism annually.[when?][34] According to scholar Todd Hartch of Eastern Kentucky University, by 2005, around 6 million Africans converted to Christianity annually.[35]
Conversion into Christianity has significantly increased among Korean,[36] Chinese,[37] and Japanese in the United States.[38] In 2012, the percentage of Christians in these communities were 71%, 30% and 37% respectively.[39]
Due to conversion, the number of Chinese Christians increased significantly from 4 million before 1949 to 67 million in 2010.[40][41]
The 2015 Believers in Christ from a Muslim Background: A Global Census study published by Baylor University institute for studies of religion estimates that 10.2 million Muslims converted to Christianity based on global missionary data.[53] Countries with the largest numbers of Muslims converted to Christianity according to this study include Indonesia (6,500,000),[54] Nigeria (600,000),[54] Iran (500,000 versus only 500 in 1979),[54] the United States (450,000),[55] Ethiopia (400,000) and Algeria (380,000).[54]Indonesia is home to the largest Christian community made up of converts from their former Islamic faith; according to various sources, since the mid and late 1960s, between two million and 2.5 million Muslims converted to Christianity.[56][57][58][59][60][61][62]
According to the Council on Foreign Relations, in 2007 experts estimated that thousands of Muslims in the Western world were converting to Christianity annually, but did not publicize their conversions due to fear of retribution.[63]
Church membership in 2019 was 1.34 billion people[64] (18% of the global population at the time), increasing from the 1950 figure of 437 million[65] and 654 million in 1970.[66][67] On 31 December 2008, membership was 1.166 billion, an increase of 11.54% over the same date in 2000,[68] and slightly greater than the rate of increase of the world population (10.77%). The increase was 33.02% in Africa,[68] but only 1.17% in Europe. It was 15.91% in Asia, 11.39% in Oceania, and 10.93% in Americas.[68] As a result, Catholics were 17.77% of the total population in Africa, 63.10% in Americas, 3.05% in Asia, 39.97% in Europe, 26.21% in Oceania, and 17.40% of the world population. Of the world's Catholics, the proportion living in Africa grew from 12.44% in 2000 to 14.84% in 2008, while those living in Europe fell from 26.81% to 24.31%. However, Catholic numbers have grown in Scandinavia where the Catholics in Nordic dioceses have tripled or even quadrupled. For example, in Denmark, Norway, Sweden and Finland, 330,000 Catholics have now registered in their dioceses.[69][70] Membership of the Catholic Church is attained through baptism,[71] and from 1983 to 2009, if someone formally left the Church, that fact was noted in the register of the person's baptism.
Monsignor Vittorio Formenti, who compiles the Vatican's yearbook, said in a 2008 interview with the Vatican newspaper L'Osservatore Romano that "For the first time in history, we are no longer at the top: Muslims have overtaken us." He said that Catholics accounted for 17.4 percent of the world population—a stable percentage—while Muslims were at 19.2 percent. "It is true that while Muslim families, as is well known, continue to make a lot of children, Christian ones on the contrary tend to have fewer and fewer", the monsignor said,[72] though Africa and parts of Asia are the exception. If the UN report in 2018 is on target, Africa's population will grow to 4.5 billion by 2100, adding to all African religious groups.[73] Muslims in 2010 represented as much as 23.4% of the total world population and this is expected to increase to 26.3% by 2030.[74] In 2016, the global Catholic population was projected to grow to 1.63 billion in 2050.[75]
According to Mark Jürgensmeyer of the University of California, popular Protestantism is one of the most dynamic religious movements in the contemporary world.[76] Changes in worldwide Protestantism over the last century have been significant.[77] Since 1900, due primarily to conversion, Protestantism has spread rapidly in Africa, Asia, Oceania and Latin America.[78]
There are more than 1.17 billion Protestants worldwide,[79][1][80][81][82][83][84] among approximately 2.4 billion Christians.[79][85][86][87] In 2010, a total of more than 800 million included 300 million in Sub-Saharan Africa, 260 million in the Americas, 140 million in Asia-Pacific region, 100 million in Europe and 2 million in Middle East-North Africa.[1] Protestants account for nearly forty percent of Christians worldwide and more than one tenth of the total human population.[1]
The U.S. Center for World Mission stated a growth rate of Christianity at 2.3% for the period 1970 to 1996 (slightly higher than the world population growth rate at the time). This increased the claimed percentage of adherents of Christianity from 33.7% to 33.9%.[101]
The World Christian Database as of 2007 estimated the growth rate of Christianity at 1.32%. High birth rates and conversions were cited as the main reasons.[102]
Using data from the period 2000–2005 the 2006 Christian World Database estimated that by number of new adherents, Christianity was the fastest growing religion in the world with 30,360,000 new adherents in 2006. This was followed by Islam with 23,920,000 and Hinduism with 13,224,000 estimated new adherents in the same period.[103]
According to 2011 Pew Research Center survey, there are more than 2.2 billion Christians around the world in 2010, up from about 600 million in 1910.[1]
The 2015 "Believers in Christ from a Muslim Background: A Global Census" estimates 10,283,700 Muslim converted to Christianity around the world.[53]
On 2 April 2015, the Pew Research Center published a Demographic Study about "The Future of World Religions: Population Growth Projections, 2010-2050" with projections regarding Christianity.[104] The projection begins with 2010 statistics when "Christianity was by far the world's largest religion, with an estimated 2.2 billion adherents, nearly a third (31%) of all 6.9 billion people on Earth. Islam was second, with 1.6 billion adherents, or 23% of the global population."[104]
Over the 2010-2050 period, Christians will remain the largest religious group with 30.7% of the world's population. However, Islam will grow faster and become 29.7% of the world's population. Therefore, by 2050 there will be 2.8 billion Muslims compared to 2.9 billion Christians.
"In the United States, Christians will decline from more than three-quarters of the population in 2010 to two-thirds in 2050".
"Four out of every 10 Christians in the world will live in sub-Saharan Africa".
Reasons given for the projected growth
Some of the reasons the Study gives are as follows:[104]
The change in the world's religious is "driven primarily by differences in fertility rates and the size of youth populations among the world's major religions, as well as by people switching faiths".
Fertility rates. "Religions with many adherents in developing countries, where birth rates are high, and infant mortality rates generally have been falling, are likely to grow quickly." Therefore, much of the growth of Christianity is projected to take place in sub-Saharan Africa. Globally, Christians have a birth rate of 2.7 children per woman. But Muslims have a higher rate, namely, an average of 3.1 children per woman. This differential is one of the reasons that the Muslim population is growing faster than the Christian.
Size of youth population. "In 2010, more than a quarter of the world's total population (27%) was under the age of 15." Christian youth under 15 were the same as the 27% global average. But an even higher percentage of Muslims (34%) were younger than 15. This higher youth population is one of the reasons that from 2010 to 2050 Muslims are projected to grow faster than Christians.
Size of old population. In 2010, "11% of the world's population was at least 60 years old", 14% of the Christian population was over 60 years old, but only 7% of Muslims were over 60. This is another reason that Muslims are projected to grow faster than Christians.
Switching. A loss of 66 million Christians is projected to come through switching. Most of the loss is projected to come from Christians "joining the ranks of the religiously unaffiliated".
Christianity has been estimated[1] to be growing rapidly in Latin America, Africa, and Asia.[87] In Africa, for instance, in 1900, there were only 8.7 million[1] adherents of Christianity; now there are 390 million,[1] and it is expected that by 2025 there will be 600 million Christians in Africa.[1] The number of Catholics in Africa has increased from one million in 1902 to 329,882,000.[1] From 2015 to 2016 alone, Africa saw an increase of 49,767,000 Catholics, a larger increase than any other continent.[106]
According to scholar Todd Hartch of Eastern Kentucky University, by 2005, around 6 million Africans converted to Christianity annually.[35]
According to scholar R.V. Dmitriev, over 3.3 million African converted to Christianity in 2010.[107]
A 2015 study estimates 2,161,000 Muslim Africans that convert to Christianity.[53]
Since 1960 a growing number of Algerian Muslims are converting to Christianity.[108][109][110][111][112]
Converts to Christianity may be investigated and searched by the authorities.[113] Conversions to Christianity have been most common in Kabylie, especially in the wilayaofTizi-Ouzou.[114]
A 2015 study estimates 380,000 Muslims converted to Christianity in Algeria.[53]
Since 1960 a growing number of Moroccan Muslims are converting to Christianity.[116][117][118][119][120]
On 27 March 2010, the Moroccan magazine TelQuel stated that thousands of Moroccans had converted to Christianity. Pointing out the absence of official data, Service de presse Common Ground cites unspecified sources that stated that about 5,000 Moroccans became Christians between 2005 and 2010.[121] According to the International Religious Freedom Report for 2014 estimate that there may be as many as 8,000 Christian citizens throughout the country, but many reportedly do not meet regularly due to fear of government surveillance and social persecution.[122]
According to different estimates, there are about 25,000-45,000 Moroccan Christians of Berber or Arab descent mostly converted from Islam.[123] Other sources give a number of a bit more than 1,000.[124] A popular Christian program by Brother Rachid has led many former Muslims in North Africa and the Middle East to convert to Christianity. His programs have been credited with assisting in the conversion of over 150,000 former Muslims to Christianity in Morocco.[125]
A 2015 study estimates some 2,200 Christian believers from a Muslim background in the country, most of them belonging to some form of Protestantism.[115][128]
Data from 2013, show that 64,000 Argentine Jews identify themselves as Christians.[129]
The United States government does not collect religious data in its census. The survey below, the American Religious Identification Survey (ARIS) 2008, was a random digit-dialed telephone survey of 54,461 American residential households in the contiguous United States. The 1990 sample size was 113,723; 2001 sample size was 50,281.
Adult respondents were asked the open-ended question, "What is your religion, if any?" Interviewers did not prompt or offer a suggested list of potential answers. The religion of the spouse or partner was also asked. If the initial answer was "Protestant" or "Christian" further questions were asked to probe which particular denomination. About one-third of the sample was asked more detailed demographic questions.
Among the Asian population in the United States, conversion into Christianity is significantly increasing among Korean, Chinese, and Japanese.[130] By 2012 the percentage of Christians in these communities was 71%, 31%, and 38% respectively.[39]
Data from the Pew Research Center states that, as of 2013, about 1.6 million adult American Jews identify themselves as Christians, most as Protestants.[131][132][133] According to the same data, most of the Jews who identify themselves as some sort of Christian (1.6 million) were raised as Jewish or are Jews by ancestry.[132] According to a 2014 study by the Pew Research Center, 19% of those who say they were raised Jewish in the United States, consider themselves Christian.[134]
According to Pew Research, Christianity loses more people than it gains from religious conversion. It found that 23% of Americans raised as Christians no longer identified with Christianity, whereas 6% of current Christians converted.[135] This was in contrast to Islam in America, where the number of people who leave the religion is[when?] roughly equal to the number who convert to it.[135] The National Catholic Register claims that in 2015 there were 450,000 American Muslimconverts to Christianity and that 20,000 Muslims convert to Christianity annually in the United States.[136] According to scholar Rob Scott of University of Tasmania in 2010 there were "approximately 180,000 Arab Americans and about 130,000 Iranian Americans who converted from Islam to Christianity".[137]
Religious Self-Identification of the U.S. Adult Population: 1990, 2001, 2008[138] Figures are not adjusted for refusals to reply; investigators suspect refusals are possibly more representative of "no religion" than any other group.
The ARIS 2008 survey was carried out from February–November 2008 and collected answers from 54,461 respondents who were questioned in English or Spanish.
The American population self-identifies as predominantly Christian but Americans are slowly becoming less Christian.
86% of American adults identified as Christians in 1990 and 76% in 2008.
The historic Mainline churches and denominations have experienced the steepest declines while the non-denominational Christian identity has been trending upward particularly since 2001.
The challenge to Christianity in the United States does not come from other religions but rather from a rejection of all forms of organized religion.
34% of American adults considered themselves "Born Again or Evangelical Christians" in 2008.
The U.S. population continues to show signs of becoming less religious, with one out of every seven Americans failing to indicate a religious identity in 2008.
The "Nones" (no stated religious preference, atheist, or agnostic) continue to grow, though at a much slower pace than in the 1990s, from 8.2% in 1990 to 14.1% in 2001, to 15.0% in 2008.
Asian Americans are substantially more likely to indicate no religious identity than other racial or ethnic groups.
One sign of the lack of attachment of Americans to religion is that 27% do not expect a religious funeral at their death.
Based on their stated beliefs rather than their religious identification in 2008, 70% of Americans believe in a personal God, roughly 12% of Americans are atheist (no God) or agnostic (unknowable or unsure), and another 12% are deistic (a higher power but no personal God).
America's religious geography has been transformed since 1990. Religious switching along with Hispanic immigration has significantly changed the religious profile of some states and regions. Between 1990 and 2008, the Catholic population proportion of the New England states fell from 50% to 36% and in New York it fell from 44% to 37%, while it rose in California from 29% to 37% and in Texas from 23% to 32%.
Overall the 1990–2008 ARIS time series shows that changes in religious self-identification in the first decade of the 21st century have been moderate in comparison to the 1990s, which was a period of significant shifts in the religious composition of the United States

Asia has the second largest Pentecostal-charismatic Christians of any continent, with the number growing from 10 million to 135 million between 1970 and 2000".[33]
According to scholars Khalil Bilici, during the Bangladesh Liberation War (March–December 1971), a significant number of Bangladeshis left Islam to join Christianity (because missionaries stood with them during their difficult times during the civil strife) or to atheism after 1971 due to their experience of oppression conducted by fellow Muslims from West Pakistan.[146]

Significant numbers of Muslims convert to Christianity in Iran, estimates range from 300,000 to 500,000 by various sources.[158][159][160][161][162] Other estimates put the numbers between 800,000 and 3 million.[163]
According to scholar Ladan Boroumand "Iran [as of 2020 was] witnessing the highest rate of Christianization in the world",[164] and according to scholar Shay Khatiri of Johns Hopkins University "Islam is the fastest shrinking religion in there [Iran], while Christianity is growing the fastest",[165] and in 2018 "up to half a million Iranians are Christian converts from Muslim families, and most of these Christians are evangelicals",[166] and he adds "recent estimates claim that the number might have climbed up to somewhere between 1 million and 3 million".[167]
Christianity is reportedly the fastest growing religion in Iran with an average annual rate of 5.2%.[168] A 2015 study estimates between 100,000 and 500,000 believers Christians from a Muslim background living in Iran, most of them evangelical Christians.[115]
Several thousand Israelis practice Messianic Jewish denominations, which are often considered as Christian sects. The Messianic Jews usually combine Jewish and Christian practices but do recognize Jesus as the Messiah. There are no exact numbers on those communities, but it is believed that several hundred to several thousand ethnic Jews belong to this tradition as well as several thousand Israelis of mixed ancestry (mostly mixed Jewish and Slavic).

A study of the religious lives of university students in Beijing published in a mainland Chinese academic journal Science and Atheism in 2013 showed Christianity to be the religion that interested students most and the most active on campuses. It concluded there was a "religious fever" in society and "religious forces were infiltrating colleges." With the support of "overseas religious forces," it said, there was a rapid growth in Christianity among university students. It said Christian fellowships on campus mostly refused to succumb to the leadership of the state-backed churches and thus posed "a problem" in the government's administration of religious affairs.
