For the most part, WYD pilgrims consider that their Christian faith is a positive factor for maturing and being a better person, building a better world, showing solidarity, understanding others, and living a happy life.

According to the study, almost two-thirds of attendees are women (62%) and 4 out of 10 are between 18 and 25 years old, while almost a third are over 35. Eighty-two percent have higher education, 6 out of 10 have a job, and just over a third are students.

Regarding their religious practice, 83% go to Mass on Sundays, 65% pray daily, and 62% belong to a parish group.

In 36% of the cases, participants have been accompanied by a religious group or association, 29% by their parishes, and 27% are alone or with a group of friends.

For two-thirds of the attendees, it will be the first time they have participated in a WYD. Those who have gone to WYDs before consider their experiences at previous events to be very positive or positive (99%) and recognize that these experiences have had a great influence on their lives (92%).

The survey was prepared by the Spanish company GAD3 through online interviews conducted from July 12–20 with almost 12,600 young people from 100 countries.
