A photographer spent a year documenting 30-year-olds around the world -- here's what he found

Turning 30 is a big deal. In western culture, this age generally marks the beginning of your “adult life” — when you’re supposed to get married, start having children, and settle into your career path. Key words being “supposed to.”

Last year, Stephane Domingues, a small-business consultant living in Paris, France, set out on a 15-month expedition around the world. In order to give his trip purpose, the 31-year-old decided to meet and document the lives of other people his age. He wanted to see how nationality, culture, and living situations shape our values and define our identities.

Now, Domingues aims to publish a book of portraits from his interactions with 30-year-olds across five continents. Check out the book on Kickstarter to learn more.

'Turning 30 was quite an important event in my life,' Stephan Domingues tells Tech Insider. 'I felt it was the case for people around me.'

Domingues spent a few months trying to organise his travel itinerary and a few years preparing financially, but ultimately left his route in 'the hands of destiny.'

He left Paris with his trusty Fuji X-T1 camera and a one-way ticket to Addis Ababa, Ethiopia.

There, he met one of his first subjects: Bori Balachew, a cattle farmer and father of five living in a small village in Ethiopia's South Omo Valley.

Balachew has kept cattle and farmed on his family's plantation since he was eight or nine. He considers himself young until he buys more cows, an indicator of wealth.

Balachew described his greatest accomplishment as participating in a Hamer tribe ritual, during which he lived in the bushes and could only drink goat blood and milk.

After meeting Balachew, Domingues (pictured left) bopped around from country to country in search of more 30-year-olds to photograph for his series.

He found his subjects on social networking apps such as Airbnb, Instagram, Tinder, and Couchsurfing. Others he met on the street or through friends.

No two portrait sessions were the same. They lasted anywhere between a few hours and a week.

Domingues shadowed people at home, on their commutes, during work, and while socialising with friends or family.

He always carved an hour for an interview, during which he asked the same questions about life, fears, ambitions, and memories.

Faruk Gomes Antonio, a fisherman from Mozambique, says the event that most shaped his life happened when he was 12. An armed group entered his village, and his family ran to the beach and hid.

He said his best memory is 'right now,' because, 'I am able to have a better job and income than ever before.'

The death of the former Argentinean president affected her most. She heard the news on the radio and cried. 'This made me realise what was my real political opinion,' Rapoport said.

Her best memory is overcoming her fears and performing a solo piano concert.

Domingues was surprised by the diversity in his profiles. 'Life is at the same time very different and very similar everywhere,' he tells Tech Insider.

'At 30 I feel like I am trying to find the right balance in my life. I do not feel that old because I am a lifelong learner,' Surapat said. 'I may also feel young because I look younger than my age, even compared to my twin brother.'

On the other side of the world, Domingues met serial entrepreneur Maceo Pasiley, who served five years doing logistics with the US Army before settling in Los Angeles.

He was 16 when the terrorist attacks occurred on September 11. 'I told myself it was an accident, but then realised that someone did it on purpose,' Paisley said. 'I joined the Army two years after 9/11 because I wanted to give back to my country.'

Today he drives his '70s Mercedes to his various ventures, which include a sock company. 'They say that in your 30's you settle in your identity,' Paisley said, 'and I feel that's very much truth.'

Many of Domingues' subjects said their lives hardly matched their expectations of being 30.

'When I go out and get drunk, I need two or three days to recover. That is quite new,' Martins joked. 'Regarding the mind, I am starting to think much more about my future than I used to.'

'(My perception has) really changed from the vision we get in the news, where the world looks gloomy, dark, and full of war,' Domingues says. 'The human being is not as bad.'
