When Nursing Counted for 6. 58% of England’s Economy

Nursing work in England did not sit outside the economy. It quietly shaped children’s body health, thinking skills, and future development. Yet most of this work was not paid through formal labor markets. That means its value could be easy to miss.

Researchers used historical records and bioarchaeological evidence to estimate breastfeeding length across about five centuries. They also used interval regression to build a range of possible values. The safest floor is that unpaid breastfeeding was always more than 0.1% of England’s gross domestic product. At its highest point, it may have reached 6.58% of GDP in the sixteenth century, when the broader economy was not growing much.

That number changes the picture. The estimate is larger than spending on schools and apprenticeships in early modern England. So breastfeeding may have been one of the biggest sources of human capital investment at the time. It shows that future capacity was not built only in classrooms or paid workplaces.

The value did not stay the same forever. As the wider economy grew, breastfeeding’s share gradually declined. For much of English history, its income elasticity appears to have been negative. That means its economic role often moved against income. It only became positive at some point in the nineteenth century.

The link with infant mortality also complicates older ideas. Breastfeeding was strongly tied to lower infant death rates. So the past does not fit a simple story where richer societies just choose less breastfeeding. It points to a more mixed link between income, survival, and family labor.

Breastfeeding was not a fixed biological habit across time. It was a changing part of economic life. If work can shape health and future capacity for centuries, why is it so easy to leave out of economic accounts?
