Record numbers of young Japanese do not have boyfriends or girlfriends, and many do not want one, according to a survey by the country's government.

根据日本政府的一项调查，没有男友或女友的日本年轻人的数量创下历史新高，而且许多人不想交男女朋友。

Sixty-one percent of unmarried men aged¹ 18 and 34 do not have a partner, nor do half of unmarried women the same age.

The numbers have increased since the previous survey in 2005.

Japan has one of the lowest birth rates in the world - and its population is on course to shrink dramatically by the middle of the century.

So every five years the government carries out a detailed² survey of attitudes to sex and marriage.

The latest found that 61% of unmarried men aged 18 to 34 have no girlfriend, and half of women the same age have no boyfriend - a record high.

More than a quarter of the men and 23% of the women said they were not even looking.

Some cited³ a shortage⁴ of money, others a belief that it is impossible to find a good partner once they had passed the age of 25.

Many of the women also said single life suited them better than how they imagined marriage would be.

The survey also found that more than quarter of unmarried men and women between 35 and 39 years old said they had never had sex.
