In total, 826 young people slept on the streets of London at least once in 2015-16, 5% less than last year.
The figure, however, represents a 32% rise compared to 2011/12.
The YMCA says it is concerned that more than 10% of people who slept rough in 2015-16 were aged 18 to 25-years-old.
Liam Preston, from YMCA England, told Premier, although the drop is good, too many people are still sleeping on the street.
He said: "I think everybody has a responsibility for dealing with this particular problem and, actually, there are faith groups like ourselves that are going out there and are supporting [the] homeless, especially young people.
"So, I think everybody in society has a role to play but those of faith who want to get involved, go and seek out your local organisation that you can help with."
YMCAs in London:
- Provide almost 1,600 bed spaces every night
- Provide training and education services to 50,000 people every year
- Health and wellbeing services; 71,000 people attending gyms annually
- Eight London YMCAs; 2,600 childcare places and 27,000 before or after school services for children and young people
- 3,000 young people attend youth clubs
- Support 600 young people in need of drug or counselling services
Figures running from April 2015 to March 2016 show, across all age ranges, rough sleeping in the capital rose by 7% over the 12 months, up to 8,096.
Liam Preston added that it is not just up to churches to solve the problem but everyone has a duty to help others.
He shared his prayer with Premier: "I think it's just to try and give hope, and that's the main thing.
"A lot of these people will be in such dire states, and they're looking around asking for help and support and actually we need to do everything we can do help and support them, so that's what I'll be praying for."
