Participation statistics 
Gallup International indicates that 41% of American citizens report they regularly attend religious services, compared to 15% of French citizens, 10% of UK citizens, and 7.5% of Australian citizens.
However, Hadaway, Marler, and Chaves found during the early 1990s that church attendance was only about 20% on an average Sunday in one rural Ohio county, whereas self-reported church attendance was 36%. Many people over-report church attendance because of their self-perception and identity as churchgoing people; this indicates a certain psychological aspect to the overreporting of church attendance. Although questions of church attendance are intended by polling organizations to study Americans' religious behavior, many respondents view them as questions about their identity. This is especially true among those Americans who consider themselves "regular churchgoers." Despite many news outlets attempting to cash in on these findings by claiming that Americans "lie" about their church attendance, Hadaway et al. have been extremely wary of accusing these over-reporters of dishonesty; as they found in one study, those who over-report do so mainly to maintain perceptions of themselves as "churched" Americans, not because they are afraid to reveal to the interviewer that they are "bad Christians."
In a 2006 online Harris Poll (they stated that the magnitude of errors cannot be estimated due to sampling errors, non-response,etc.; 2,010 U.S. adults were surveyed) found that only 26% of those surveyed attended religious services "every week or more often", 9% went "once or twice a month", 21% went "a few times a year", 3% went "once a year", 22% went "less than once a year", and 18% never attend religious services. An identical survey by Harris in 2003 found that only 26% of those surveyed attended religious services "every week or more often", 11% went "once or twice a month" 19% went "a few times a year", 4% went "once a year", 16% went "less than once a year", and 25% never attend religious services.
The country with the highest rate of church attendance in the world is Nigeria (89%). Nigeria is unusual, as it is very religiously diverse - the population is 50.5% Muslim, 48.2% Christian. Other examples tend to be religiously homogenous.
Weekly church attendance statistics 
Following attendance statistics are mainly taken from the 2004 Gallup report and do not represent current attendance figures that generally are lower due to ongoing secularisation.
|Country||Attendance (%)||Country||Attendance (%)||Country||Attendance (%)||Country||Attendance (%)|
|Austria||18% ||Belgium||7% ||Canada||20%||Denmark||3% |
|Cyprus||25% ||Czech Republic||11% ||Estonia||4% ||Finland||5% |
|France||12% ||Greece||27% ||Hungary||12% |
|Ireland||46% ||Italy||31% ||Latvia||7% ||Lithuania||14% |
|Malta||75% ||Norway||3% ||Poland||63% ||Portugal||29% |
|Slovakia||33% ||Slovenia||18% ||Spain||21% ||Sweden||5% |
|United Kingdom||12% ||United States||43%|
A study by the European Social Survey conducted in 2008 found these rates of respondents never attending religious service (excluding special occasions):
- <10%: Cyprus, Greece, Poland
- 10-20%: Croatia, Italy, Ukraine
- 20-30%: Turkey (Islam), Portugal
- 30-40%: Estonia, Russia, Germany, Sweden
- 40-50%: Israel (Judaism), Spain, Netherlands
- 50-60%: Belgium, Britain, France
- >60%: Czech Republic
Trends in church attendance 
Church attendance in developed countries has gradually declined. Research has attributed this to lack of motivation, negative media coverage of religion and boredom during the services. One study published in the Journal of the Scientific Study of Religion, however, argues that at least in America, church attendance since the 1990s has remained stable at 25%. A Gallup poll found that church attendance among Protestants has remained stable at roughly 45% since 1955, while church attendance among Catholics has dropped from 75% to 45%, although it has remained stable since 1995, despite negative stories in the news. Another Gallup poll found a slight increase in church attendance over the past two years; associating this with an aging population. This decline is particularly pronounced in European countries, where it is suggested that the secular culture overrides interest in religion.
Demographics of church attendees 
Church attendance remains stronger among older adherents, and more common in women. Some research asserts that younger generations show greater levels of religious adherence than the baby boomers, many of whom brought up their children in a non-religious environment.
The Pew Research Center has linked weekly church attendance with happiness. The Iona Institute found increasing church attendance in Ireland, despite sex-abuse claims within the dominant Catholic Church. The authors suggest the rise is due to the effects of the recession.
Studies in general indicate that there is a higher rate of church attendance among married couples and those with bachelor's degrees than any other group. For instance, in a Pew Research survey from 1996, approximately 34% of high school dropouts went to church on a typical Sunday, while 44% of those with a college degree or higher did. 48% of married individuals attended church on a typical Sunday, compared to 29% of divorced and 31% of never-married individuals. While it is likely that the well-educated and married might over-report their church attendance more often, nevertheless these findings demonstrate that they have maintained a stronger church-going identity than other Americans.
A number of studies have been undertaken to examine the topic of religiosity and intelligence and religiosity and education.
Influence of men on church attendance 
Switzerland released a study in 2000 which concluded that the religious practice of the father of the family determines the future attendance or absence from church by the children. If both father and mother attend regularly, 33 percent of their children will end up as regular churchgoers, and 41 percent will end up attending irregularly. A quarter of their children will end up not practicing at all. If the father is irregular and mother regular, 3 percent of the children will subsequently become regulars themselves, while a further 59 percent will become irregulars. Thirty-eight percent will not attend at all. If the father is non-practicing and mother regular, 2 percent of children will become regular worshippers, and 37 percent will attend irregularly. About 60 percent of their children will not attend at all.
In short, if a father does not go to church, no matter how faithful his wife’s devotions, only one child in 50 will become a regular worshipper. If a father does go regularly, regardless of the practice of the mother, between two-thirds and three-quarters of their children will become churchgoers (regular and irregular). If a father goes but irregularly to church, regardless of his wife’s devotion, between half and two-thirds of their offspring will attend church regularly or occasionally.
A non-practicing mother with a regular father will see a minimum of two-thirds of her children ending up at church. In contrast, a non-practicing father with a regular mother will see two-thirds of his children not attending church. If his wife is similarly irregular that figure rises to 80 percent.
