Desecularization and aging populations

The article Developed countries may become more religious in 20 years indicates:

“

Researchers from HSE University and RANEPA found that in high-income countries, age, rather than the cohort effect, has more impact on religiosity. They predict that this may have an impact on societal structure in the future. The study was published in Journal for the Scientific Study of Religion. It has long been observed that older people tend to be more religious than younger people. However, it is still disputable whether this fact should be attributed to people generally becoming more religious with age per se (age effect), or to the process of secularization, wherein earlier cohorts (to which the now older people belong) used to be more religious than those that appeared later, i.e. younger cohorts (cohort effect). HSE University scholars decided to analyze this issue using data from six waves of the World Values Survey (2016) in high-income OECD countries. A total of 16 countries were studied, including Australia, the USA, Canada, Great Britain, Israel, New Zealand, Japan, Germany, as well as other European countries. The researchers used logistic models and multiple linear regression to determine that the age effect has a higher impact on religiosity than the cohort effect. Older people are more inclined to believe in God, attend church, and believe it is important to instill religion in children.. The cohort effect impacts other factors analyzed by the scholars, such as church attendance and a belief in religion's importance in life, but the age effect still strongly prevails over the cohort effect.
