Over the past few decades, social scientists like me have found consistent evidence that there is an almost zero association between having children and happiness. My analysis in the Journal of Socio-economics (Powdthavee, 2008) is a recent British example of parents and non-parents reporting the same levels of life satisfaction, on average.
But the warnings for prospective parents are even more stark than ‘it’s not going to make you happier’. Using data sets from Europe and America, numerous scholars have found some evidence that, on aggregate, parents often report statistically significantly lower levels of happiness (Alesina et al., 2004), life satisfaction (Di Tella et al., 2003), marital satisfaction (Twenge et al., 2003), and mental well-being (Clark & Oswald, 2002) compared with non-parents.
There is also evidence that the strains associated with parenthood are not only limited to the period during which children are physically and economically dependent. For example, Glenn and McLanahan (1981) found those older parents whose children have left home report the same or slightly less happiness than non-parents of similar age and status. Thus, what these results are suggesting is something very controversial – that having children does not bring joy to our lives…
HO HO! SCIENCE AGREES.
