Skeletal evidence reveals harsh physical toll of child labor in postmedieval Netherlands

A new analysis of Dutch skeletal remains from the 1600s–1800s shows that children as young as four, who often worked 12–17 hour days, developed severe spinal degeneration typically seen in much older adults. Researchers documented worn vertebrae, bony growths, and disc damage in individuals aged 4–25, indicating the lifelong impact of grueling labor. The findings, published in the International Journal of Paleopathology, highlight the physical consequences of child labor that historical records largely ignored.

The study compared skeletal remains from three distinct Dutch communities: rural dairy workers in Middenbeemster, urban factory laborers in Arnhem, and affluent non-working children from Delft. Researchers found that Middenbeemster children, who hauled milk basins and cheese molds from age nine, suffered the most severe spinal damage, including worn joints, bony growths on vertebrae edges, and Schmorl's nodes—disc herniations caused by spinal pressure. Surprisingly, Arnhem's factory children showed spinal conditions closer to their wealthy Delft counterparts, suggesting that sedentary textile work, though exhausting over 12-hour shifts, placed less mechanical stress on young spines than agricultural lifting. The study analyzed 143 individuals aged 4–25, with some damage appearing before children lost their baby teeth.
