As the media cycle lurches from the promotion of one existential crisis to another, demography continues to dominate. In the UK, low birth rates and ageing populations mean we won’t be able to afford healthcare and pensions; we have too many of the “wrong type” of immigrants and too much of the “wrong type” of emigration. Of course, some countries have it worse. China, having shot itself in the groin with its one-child policy, is set to become smaller than India, for whom a growing population could be either a blessing or a curse (take your pick). Globally, fertility rates are falling, but eco-worriers remind us that “overpopulation” continues to contribute to the climate emergency.
Amid such hysteria it’s unclear whether we should be encouraging the patter of tiny feet or reducing the reproduction of ginormous carbon footprints. What is clear, however, is that none of this hyperbolic claims-making is really about demography — a complicated and specialist discipline based on the statistical study of human populations. It’s more about doomography — a fatalistic cultural trend that relies on elementary maths about big and small numbers to give a clever-looking veneer to sublimated anxieties about social and economic problems.
In my research field of generational conflict, for example, tensions over housing, pensions, cultural values and a range of other issues are routinely treated as problems arising from having more older people than younger people. This evades the nuanced discussions that need to be addressed in their own terms: inciting kids to “mug Grandma” for her pensioner perks will do nothing to help today’s workers gain a better standard of living now.
Worse, the doomographic mindset evades the very question it pretends to focus on: why have we become turned off reproduction? While acknowledging the problem of demographic determinism, it is surely right to think that a slowdown in population growth represents something significant and potentially troubling, and to consider its potential causes. Sociologically, one trend that stands out, certainly in Western societies, is the discomfort we have with the idea of renewing ourselves.
The study of generations involves engaging with reproduction on three levels: biological, social and cultural. Biological reproduction is common to all species, but for humans, having a baby usually involves the prior decision that this is something you want to do. It’s a personal choice, assisted by modern reproductive technologies but not given by these — birth rates tend to fall as societies develop, regardless of access to contraception or abortion. But like all choices, having a baby is framed by prevailing social and cultural dynamics and relationships. At its most basic, if having a child is seen as a key component of a meaningful life, people will couple up and get on with it; if becoming a parent is regarded as a troublesome burden, couples — or one half of a couple — are likely to dither, delay or decide that it’s all too much bother. And they do so in a context where their peers are wrestling with the same anguished choices.
It’s hardly controversial to suggest that the prevailing sentiment of cultural pessimism in Western societies makes the 2020s an inhospitable time for a baby boom. Yet the narrow instrumentalism of doomographic thinking leads to wishful thinking as well as apocalyptic prophesying. For instance, attempts to explain why young people delay, or avoid, having children as a consequence of purely economic factors often lead to reductive claims about the prohibitive cost of housing or childcare. Now, these factors certainly make it more difficult to start and sustain a family, and policy should address them — but our ancestors managed to create us despite having much less wealth. Focusing only on the factors that frame individual decisions also misses the bigger question, of what drives societies to reproduce themselves in the first place.
