The pregnancy rate among teenagers Doncaster is at a record low, and experts believe this is because sexting is replacing physical relationships.
In 1998, when the Office for National Statistics first started compiling conception data by local authority, the pregnancy rate for young women in the borough aged between 15 and 17 was 74 per 1,000.
In the 12 months up to June 2017, the period covered by the latest statistics, that figure more than halved to 25 per 1,000.
Katherine O’Brien, spokeswoman for the British Pregnancy Advisory Service, said cultural changes among young people, such as drinking less and spending more time socialising online, had caused under 18 pregnancy rates to plummet.
She said: “Under 18 conception rates have been falling dramatically, particularly over the last decade, and they currently stand at record lows.
“Improvements in contraception and better sex education undoubtedly play a role, however we believe some societal shifts are also important factors.
“This is a generation who focus on their academic work much more, they are less likely to go out binge drinking and get involved in activities which can lead to sex.
“They are spending more and more time socialising online, and less time in person with their partners.”
In total, 123 young women under 18 became pregnant in Doncaster in the 12 months to June 2017.
While the under 18 conception rate has fallen in the town, it is still above the average figure for Yorkshire and the Humber, which is 21 per 1,000 young women
