The number of under-25s sleeping rough in London has doubled since 2011.
A new survey has revealed that 18% of people aged between 16 and 25 in the UK slept rough in the past year.
The homeless charity Centrepoint commissioned ComRes to speak to 2,000 young people.
Almost 1 in 5 revealed they had slept on the street, on night buses, or in cars because they had nowhere else to go.
Of those who said they had experience of sleeping rough in the last year, 2 in 5 said they spent one night doing so and one-third said they did so for between one night and one week.

"Even if it's just for one night, it can just be the beginning."
Our poll proves the issue of young people sleeping rough is huge and nobody else is giving an accurate picture of the problem.
The government's only data on rough sleeping does not break down by age and is limited to estimates and a one-night snapshot survey.
From this it's impossible to ensure that vital support services for homeless young people are available in the right place at the right time.
Centrepoint said the number of people under the age of 25 forced to sleep rough in London had more than doubled since 2011.
It also pointed out that young homeless people are twice as likely to die as their peers.
