London - Britain has the world's highest rate of unmarried teenage mothers, a survey disclosed yesterday. The first worldwide survey of young women's sexual activity shows that 87 per cent of the 41,700 children born to 15-19-year-old teenagers in the UK were outside marriage. This compares with 62 per cent in the US and 10 per cent in Japan.
It is higher than the rate in Third World countries, according to the survey of 53 countries, including six from the developed world.
