The training is in full swing in the Husby Hall in northwest Stockholm.

Rana Abou Hachem, 14, runs in a counter, catches the ball and fires off the ball against the basket, raised by five-year-old coach Mary Kassa.

What we see is what BK Järva describes as the reason for the club's success.

Around the country, football is usually the biggest sport that attracts young people.

In Husby in north-west Stockholm, which is defined by the police as a particularly vulnerable area, is the basket. In total, more than 7 out of 10 children and young people are active in one of Husby's sports associations, SVT's survey shows. More than 700 of the young people in the area, including a majority of girls, play in BK Järva.

Jan "Isse" Isaksson

- We have the most young girls who are leaders in the club, says Jan Isaksson.

"Isse", as everyone here calls him, grew up in Husby and has been with the club for over three decades.

The parental tradition is missing

Like all associations, BK Järva needs parents who volunteer as coaches and on other assignments. But that is a constant challenge.

- I see a big difference to how it used to be. We have a lot of trouble getting parents involved, says Jan Isaksson.

He says that the same tradition does not exist in the area to participate in the association life and that the parents do not have time.

- It feels like they work a lot of nights. Many people drive taxis and work in healthcare or care, says Jan Isaksson.

Young leaders are nurtured

Instead, the club has invested in nurturing young leaders. The youngest is 13 years old and can train seven-year-olds.

- It's mostly play, but with a basketball in hand, says Jan Isaksson.

That is the reason why the basketball and the association are so popular, he says.

Being a leader makes the players proud and contributes to a strong cohesion.

family Feeling

- We have a family feeling. It creates a lot of security and makes many want to participate and play. You follow a friend and discover that it is so much fun. Then it spreads, he says.

Sports scientist Johan Norberg says the club has a clear recipe for success, a challenge many associations struggle with.

- This is a great example of the most basic. You try to involve the kids by making them leaders. It causes the association to grow and the players to stay.
