Key Takeaways

01

Volunteering rates varied substantially across the 22 countries studied, with Nigeria, Indonesia, and Kenya reporting the highest proportions of volunteers (40% or more) while Japan, Poland, and Egypt reported the lowest (under 10%).

02

In a pooled analysis across all 22 countries, higher education and more frequent religious service attendance were associated with higher rates of volunteering, whereas age, marital status, and immigration status showed relatively little difference in volunteering proportions.

03

Demographic patterns in volunteering differed considerably by country, indicating that national context shapes which sociodemographic groups are more or less likely to volunteer.

Why It Matters

To build a culture of volunteering, we must first understand the complex reality of who gives their time.

This research matters because volunteering is widely recognized as beneficial — not just for the people and causes being helped, but for the volunteers themselves, who tend to experience better physical and mental health. Understanding who volunteers and who doesn't, across so many countries, helps governments, nonprofits, and public health leaders identify gaps and remove barriers. If certain groups — like people with less education, or those who never attend religious services — are volunteering less, organizations can ask why and design better ways to include them. The enormous differences between countries also suggest that national policies, cultural norms, and even historical events play a big role in shaping whether people volunteer. For example, government restrictions on charitable organizations may limit opportunities, while national service programs may encourage lifelong habits of service. By mapping these patterns globally, this study gives decision-makers a clearer picture of where volunteering thrives, where it struggles, and what might be done to make it more accessible to everyone who wants to participate.

The Story

Have you ever wondered who actually volunteers their time to help others? Researchers asked over 200,000 people across 22 countries whether they had volunteered for an organization in the past month. What they found was striking: volunteering rates varied enormously depending on where you live.

People who regularly attend religious services are more than twice as likely to volunteer their time.

In Nigeria, about 51% of people said yes. In Indonesia, it was 46%, and in Kenya, 40%. But in Egypt, only 4% reported volunteering. Japan and Poland were also under 10%.

Overall, about 24% of people across all 22 countries said they had volunteered recently. The researchers also looked at who tends to volunteer. Some patterns were clear: people with more education tended to volunteer more, and people who attended religious services frequently were much more likely to volunteer than those who never attended. Self-employed people and students also volunteered at higher rates. But other factors (like age, marital status, and whether someone was born in their country) didn't make much difference overall.

That said, when the researchers zoomed into individual countries, the picture got more complicated. In some countries, younger people volunteered more. In others, older people did. In most countries, men volunteered slightly more than women, but in a few (like Australia, Sweden, and the US), women volunteered more. The study reminds us that volunteering isn't just about individual willingness. It's shaped by culture, history, government policies, and the opportunities available. In some places, people may help informally, caring for neighbors or relatives, without calling it 'volunteering.' So low formal volunteering rates don't necessarily mean people care less about their communities.
