Seven Tenths of a Child

Britain's birth rate is 1.39. Replacement is 2.1.

The gap is seven tenths of a child per woman, and it is not a rounding error. It is the difference between a country that renews itself and one that does not.

Ask almost any young family how many children they would like and the answer has been the same for forty years: two. Ask how many they have, and it is fewer. Across the developed world, in every country that measures it, people are ending up with fewer children than they said they wanted — and almost nobody has asked why.

The usual explanations do not survive contact with the evidence. South Korea spent two hundred billion dollars and recorded the lowest birth rate in human history. Hungary spends five per cent of its national income and sits exactly where England does. France has run continuous family policy since 1939 and recorded more deaths than births in 2025 for the first time since the war. The countries with the thinnest populations have the fewest children. The countries with the most contaminated food supplies have the most.

This book proposes something different: that people reach parenthood through three stages, in order — independence, then partnership, then children — and that Britain broke the first one, quietly, over thirty years, without noticing.

It is not a book about blame. Nobody did this. There is no policy that caused it, no villain to name, no lever anybody pulled. What there is instead is a very large amount of public data that nobody has put next to itself, and a country that has been asking the wrong question since 1949

Along the way: a man who was congratulated on his hundred and eleventh birthday by officials who had not noticed he died in 1978. Two English towns thirty-two miles apart with a sixfold difference in fertility. Four million people registered with an English doctor who do not appear in the census. And the reason a third of British boys once left school on a Friday and started work on the Monday, and no longer can.

Fifty chapters. Every figure sourced and checkable. Corrections recorded rather than erased.

For anyone who has wondered why the life they expected has been so much harder to arrange than it was supposed to be — and whether that was them.
