Welfare 3 July 2013 Why is the happily childless woman seen as the unicorn of society? Non-mothers are often told they'll "change their mind when they meet the right person". Between that and being forced to worry who will visit you in your old age, it's no wonder society seems to believe the happily childless woman is more myth than realit Sign UpGet the New Statesman's Morning Call email. Sign-up Being a parent isn’t always a walk in the park, according to the World Happiness Database unveiled in Rotterdam this week. In fact, it could be bad for your mental health: one of the activities which sends happiness levels plummeting, according to the research, is having a child (although, it hastens to add, your happiness increases when they grow up and leave home - which hardly seems a glowing recommendation for having them in the first place). Meanwhile, it was reported by the BBC that China has just passed what it is euphemistically calling the "Elderly Rights Law", a piece of legislation that makes it compulsory for adult children to visit their parents in a country with a rapidly ageing (and lonely) population. In other words, you sacrifice happiness to parenthood in the prime of your life, enjoy a brief but halcyon retirement, then are abandoned in your twilight years to the extent that the government has to force your children to pop in for a cup of tea. No wonder we’re all procreating less. But the fact remains that the "childless by choice" - or, as some prefer it, "child-free" - are still looked upon as dangerous oddities, possibly with some sort of social disease. Even worse is the female half of the dreaded "childless by choice" couple, all settled down with someone they love in a perfectly good home with a spare bedroom that could be easily transformed into a nursery and just downright refusing to warm up a bun in her oven. "Tick tock", publications aimed at thirtysomething women sing-song, as you scour the magazine rack for something that doesn’t make you want to throw up, move countries, cry, or all of the above. "Your ovaries are getting old! Your eggs won’t last forever! You’ll change your mind in a few short years - and where will you be then?" It’s beyond comprehension to most of the media, of course, that women without children might not end up crying outside the local school-gates every morning before being shooed away by the caretaker. The "evolutionary science, hideously misapplied" brigade have been banging the "naturally maternal" drum for decades as an explanation for all possible facets of female behaviour. Through this lens, the female role in a heterosexual relationship is to become your male partner’s new mother, helpfully cooking and cleaning and facilitating his life for him while he has fun and plays with his friends outside. The "maternal instinct" apparently inherent in all women has been used as a way to keep mothers out of the workplace and discriminate against fathers who want equal custody of their children. The belief that we are essentially born to be baby incubators crops up again and again amongst anti-abortion debaters, and is one reason why new mothers often report feeling ashamed of postnatal depression. After all, if you’re supposed to be in your element but you feel like crap, then surely you’re a Darwinian failure of the first order - never mind if you opt out of having the baby altogether. All of this contributes to the idea of the happily childless woman as the unicorn of society. A dedicated bachelor is a good-time guy, and a married man without kids is hardly a talking point. But a bachelorette is more likely to be seen as tragic, bitter, yearning for the family that she hasn’t yet had the opportunity to create; her coupled-up counterpart a perpetual mother-in-waiting. And why should this be the case, on an overpopulated planet with a surplus of poverty, starvation and greenhouse gases? Really, it shouldn’t be the child-free who have to justify their position - it should be those who choose to bring others into the world without good reason beyond "I JUST WANT TO SEE MINI-ME". Yes, your unfortunate nose might look hilarious on an unsuspecting infant’s face - but is it really worth the extra carbon dioxide and the toe-curlingly boring hours spent poring through stacks of GCSE retake papers? After all, the lifetime cost of raising a child in the UK is now £222,458, which is a hell of a lot of luxury holidays and stiff gins down the drain, not to mention the damage those little darlings can do to your nether regions on their way into the world. Women we’ve spoken to through The Vagenda have told us that their own doctors have made it difficult for them to undergo sterilisation by condescendingly insisting that they will "only want it reversed in a few short years", as if they had chosen the procedure on a whim. Others have been told by relatives that they’re not performing their "womanly duty" by shunning motherhood - seriously - and still more have contended with the mind-bending accusations that they’re "being selfish" or "will get bored in your marriage if you don’t". By far the most common amongst our Twitter followers, however, was experience of the smug assurance that "you’ll change your mind once you meet the right person", as if a Baby Alarm will go off in every woman’s mind the moment they meet their God-given soulmate and embark upon Happily Ever After. This is apparently now wheeled out more often even than the old and reliable, "Who will look after you in your old age?", which still persists despite the fact that very few of us are living on isolated farmland dependent on continuous manual labour in countries without some semblance of a national health service. So how to stop the constant barrage of criticism if you are to live life as a contented child-free female human being? Firstly, ignore all magazines aimed at the thirtysomething demographic: there are far too many allusions to "Fertility O’Clock" and "foods to maximise your spouse’s sperm count". Secondly, have faith in social progression: a recent survey covered by the Washington Post found that the belief that "mothers are more natural parents" is much more prevalent amongst older groups of society, as it fades in the younger (two-thirds of women aged 65+ agreed with the statement, compared with about half of woman in younger age groups.) Meanwhile, grit your teeth while people loudly worry about who’s going to visit you in your nursing home and own the choice that’s right for you. Because £222,458 later, who’s to say that THEY’RE not the ones who’ll be left wanting to change their minds? Now read Lulu Le Vay's call for "Mumsnot", in which she asks whether if a woman doesn't have any kids, she still has any value. › The Marriage Tax Allowance is an expensive way of harnessing resentment and feelings of superiority The happily childless, or child-free, woman is more common than you think.
