Where Do People Find Strength in Faith? A Global Map
In Egypt, nearly everyone finds comfort in religion or spirituality — but in Japan, almost no one does.
Religious Reading across Borders and Demographics: A Study of 22 Countries
The prevalence of reading or listening to sacred texts at least daily varied substantially across 22 countries, ranging from 4% in Japan to 70% in Tanzania.
In a pooled analysis across all examined countries, religious service attendance was the only demographic characteristic for which significant differences in sacred text engagement were observed.
While cross-national pooled differences were small for most demographic traits, substantial variation in sacred text reading and listening was found within individual countries by age, gender, and education.
This research matters because it reveals a blind spot in how we study religion. Most studies focus on attendance and prayer, but reading and listening to sacred texts is a deeply personal practice that may affect people in different ways — offering comfort, guidance, moral direction, and a sense of connection to something larger. By mapping who engages in this practice across 22 countries, this study gives us the first large-scale picture of sacred text engagement worldwide. For healthcare providers and public health programs, understanding these patterns could help tailor approaches that respect patients' spiritual lives. For educators and community leaders, it highlights which groups are already engaged and which might benefit from different kinds of outreach. And for anyone curious about how religion shapes daily life around the world, this study offers a reminder that something as simple as opening a sacred book — or pressing play on an audio recording — looks very different depending on where you happen to live.
When researchers talk about religion, they usually focus on going to services or praying. But what about reading or listening to sacred texts — the Bible, the Quran, the Torah, the Vedas, and others? This study looked at that question across 22 countries and over 200,000 people.
The results were eye-opening. The percentage of people who read or listen to sacred texts every day ranged from a tiny 4% in Japan to a remarkable 70% in Tanzania. Countries in Africa, the Middle East, and Southeast Asia tended to have much higher rates than countries in Europe or East Asia. In fact, people in less wealthy, less industrialized nations were generally more likely to engage with sacred texts daily.
The study also found that people who attend religious services frequently are far more likely to read sacred texts — 71% of people who attend services more than once a week also read or listen to sacred texts daily, compared to just 8% of people who never attend. When it came to other factors like gender, age, education, and marital status, the patterns were much less clear-cut. Women read slightly more than men on average, older people tended to read a bit more than younger people, and people with less formal education read slightly more than those with more. But these differences were small and varied a lot from country to country. In some places, younger people read more; in others, it was the opposite.
The big takeaway? How often people engage with sacred texts has less to do with who they are as individuals and much more to do with the cultural and religious environment they live in.
Tanzania had the highest proportion of daily sacred text readers at 70%, compared to Japan's low of 4%.
The most frequent religious service attenders were about 8.9 times more likely to read sacred texts daily than non-attenders.
Individuals with up to 8 years of education reported more daily sacred text reading than those with 16+ years.
In the United States, Black individuals reported daily sacred text engagement at roughly twice the rate of Asian individuals.

While 95% of people in Indonesia believe in life after death, only 21% of people in Japan do.
What if childhood poverty, trauma, and family breakups have almost no universal link to adult religious belief?

In Tanzania, over 80% of people share their faith with others, while in Japan, that number is only 4%.
Surprisingly, difficult childhoods—including experiences of abuse or feeling like an outsider—can lead to a greater engagement with sacred texts in adulthood.
