The rate of early marriage is higher in rural regions than it is in urbanized areas. Fertility rates in South Asia range from 71 to 119 births a trend towards increasing age at marriage for both sexes. In South Korea and Singapore, although the occurrence of sexual intercourse before marriage has risen, rates of adolescent childbearing are low at 4 to 8 per 1000. The rate of early marriage and pregnancy has decreased sharply in Indonesia; however, it remains high in comparison to the rest of Asia. Surveys from Thailand have found that a significant minority of unmarried adolescents are sexually active. Although premarital sex is considered normal behavior for males, particularly with prostitutes, it is not always regarded as such for females. Most Thai youth reported that their first sexual experience, whether within or outside of marriage, was without contraception. The adolescent fertility rate in Thailand is relatively high at 60 per 1000. 25% of women admitted to hospitals in Thailand for complications of induced abortion are students. The Thai government has undertaken measures to inform the nation's youth about the prevention of sexually transmitted diseases and unplanned pregnancy. According to the World Health Organization, in several Asian countries including Bangladesh and Indonesia, a large proportion (26-37%) of deaths among female adolescents can be attributed to maternal causes. In 2015, the birth rate among teenage women in Australia was 11.9 births per 1,000 women. The rate has fallen from 55.5 births per 1,000 women in 1971, probably due to ease of access to effective birth control, rather than any decrease in sexual activity. The overall trend in Europe since 1970 has been a decrease in the total fertility rate, an increase in the age at which women experience their first birth, and a decrease in the number of births among teenagers. The rates of teenage pregnancy may vary widely within a country. For instance, in the United Kingdom, the rate of adolescent pregnancy in 2002 was as high as 100.4 per 1000 among young women living in the London Borough of Lambeth, and as low as 20.2 per 1000 among residents in the Midlands local authority area of Rutland. In Italy, the teenage birth rate in central regions is only 3.3 per 1,000, but, in the south in Mezzogiorno it is 10.0 per 1000. Teenage birth is often associated with economic and social issues: such as alcohol and drug misuse and, across 13 nations in the European Union, women who gave birth as teenagers were twice as likely to be living in poverty, compared with those who first gave birth when they were over 20.
