Which Age Group Volunteers Abroad the Most?

People from all walks of life choose to volunteer abroad, but have you ever wondered which age group does it the most? From students on a gap year to retirees looking for purposeful travel, international volunteering attracts a wide range of participants for different reasons and at different life stages.

Understanding who’s volunteering the most and why can offer helpful insight if you're thinking about starting your own journey. In this post, we’ll explore age-based trends and highlight why volunteering abroad is more inclusive and accessible than ever.

Who Volunteers Abroad the Most? A Look at the Data

Most international volunteers fall into the 18–35 age range, with many studies citing the 18–25 group as the most active overseas. One overview notes that short‐term “voluntourism” is particularly popular with this age bracket, which often has fewer career obligations and a desire for meaningful travel.

Meanwhile, mid-career volunteers—those aged 35–44—also play a significant role. A global survey found this group had the highest domestic volunteering rate at 32%, followed by 45–54 at 26%. While this data focuses on domestic volunteering, it's a useful indicator that mid-career adults are deeply engaged in service, often extending their commitment overseas as well.

Older adults and retirees (50+) are likewise contributing more on the global stage. A U.S. Bureau of Labor Statistics report cited by GoEco noted that 25.7% of those aged 65+ volunteered—many in international programs. UNV also highlights a growing global trend among older volunteers living longer and staying active via volunteerism.

In short:

• Young adults (18–25) lead in numbers for overseas volunteering
• Mid-career adults (35–44) show high engagement, often extending domestically to international service
• Older volunteers (65+) are increasingly visible and valued in international roles

Why Young Adults Lead in International Volunteering

The 18–25 age group consistently leads in international volunteer participation, and it’s easy to see why. At this stage in life, many young people are actively seeking purpose, growth, and global exposure, and volunteering abroad offers all of that in one experience.

Here’s why this age group often takes the lead:

• Flexibility - Many young adults volunteer during gap years, post-graduation breaks, or before entering the workforce, making it easier to commit time to travel and service.
• Career development - Volunteering abroad helps build resumes and develop skills like communication, leadership, and adaptability, especially valuable for those entering competitive job markets.
• Personal exploration - This life stage is often about self-discovery. Volunteering offers a chance to explore new cultures, challenge comfort zones, and gain a broader worldview.
• Social motivation - Many programs cater to students and early-career travelers, offering group settings and opportunities to connect with like-minded peers.

The Rise of Mid-Career and Retired Volunteers

While young adults may lead in volunteer numbers, there’s a clear and growing trend among older age groups—particularly those in their 30s, 40s, 50s, and beyond—who are choosing to volunteer abroad for entirely different reasons.

Why mid-career adults are getting involved:

• Sabbaticals and career breaks - More professionals are using extended time off to do something meaningful and recharge with purpose.
• Desire for hands-on impact - Many in this age group are motivated by the need to contribute their skills to causes they care about, beyond traditional tourism.
• Family volunteering - Some mid-career volunteers travel with their children or partners, turning service into a shared experience.

Why retirees are joining in:

• More free time and financial flexibility - Retirement offers the time and resources to travel for longer periods and give back on a deeper level.
• A lifetime of experience to offer - Older adults bring valuable perspectives, skills, and emotional intelligence to volunteer placements.
• Personal fulfillment - Volunteering offers a sense of purpose, community, and continued learning post-retirement.

Benefits of Volunteering at Any Age

No matter your age, volunteering abroad offers something valuable—both for you and for the communities you support. Each stage of life brings unique strengths and motivations that shape the experience in a different way.

For younger volunteers:

• Builds confidence and independence
• Develops real-world skills outside the classroom
• Offers exposure to new cultures and perspectives
• Boosts CVs with global experience and initiative

For mid-career volunteers:

• Creates space for reflection and renewed purpose
• Allows you to apply professional skills in new contexts
• Provides a break from daily routines while still doing something meaningful

For older adults and retirees:

• Opens the door to continued learning and contribution
• Makes use of a lifetime of knowledge and emotional insight
• Encourages personal connection, empathy, and cultural exchange

The most important thing to remember is this: the impact you make isn’t defined by your age, but by your willingness to show up, engage, and give your best. Read our guide on whether volunteering is worth it to learn more.
