A generation of young women have been putting off starting a family because it will damage their lifestyle, career and looks, a survey shows.

调查显示，英国年轻女性一代推迟生育是因为生小孩会影响她们的生活方式、职业生涯和外貌。

One in three childless women quizzed now say they don't ever want to become a mother while increasing numbers of thirty-somethings in stable relationships and with good jobs have different priorities.

Almost half would rather get on the property ladder than have a baby while 28 percent would prefer a ￡100,000 salary, according to a poll of 2,000 women.

The Grazia magazine report commissioned to coincide with the release of Sarah Jessica Parker's latest film I Don't Know How She Does It uncovered a whole new tribe dubbed¹ the 'I Don't Know Why She Does It' generation.

The film portrays² the life of a high-flying professional woman Kate Reddy, who also looks after two children in the evening and is happily married to an out-of-work architect（建筑师） .

Childless women just aren't willing to make the sacrifices they now see are necessary for motherhood with 44 percent feeling sorry for working mums struggling to have it all, the survey said.

A quarter think working mothers always look exhausted³ and one in five say it looks so difficult it makes them think twice about having children.

Half of childless women over 30 look at stay-at-home mothers and think it will be difficult for them to get back on the career ladder and a fifth believe they've lost their identity.

Body issues are also a factor with three in ten worried about the effect pregnancy⁴ would have on their appearance.

Almost a third think having a baby would make them less body confident while almost one in three mothers miss their pre-baby figure and feel judged by society thanks to coverage⁵ of glamorous⁶（迷人的） celebrity⁷ mums.

Four in ten childless women say they're not ready to give up their lifestyle - and a quarter still feel too young for a child.

Meanwhile 26 percent admit they are fearful of the effect motherhood would have on their career.

Almost half think having a child would make them poorer and over half say they couldn't afford a baby even if they wanted one.

The survey also identifies a rise in the 'emotionally infertile⁸' - childless women who feel they have left it too late to have a baby with women admitting they put their career first or they didn't meet the right man.
