Dutch height gains plateau after a century of steady increase

After decades of growth, the Netherlands’ population height has levelled off, signalling the end of a remarkable rise driven by improved nutrition and healthcare, with implications for understanding future trends.

For decades, the Netherlands seemed to defy the rest of the world by getting steadily taller. Now, according to Statistics Netherlands, that climb has levelled off, with younger generations measuring slightly less than the peak cohorts reached at the end of the last century.

The official figures show that Dutch men born in 1980 averaged 183.9 centimetres at age 19, the highest point in the series. For men born in 2001, the average had slipped to 182.9 centimetres. Women followed a similar pattern, with those born in 1980 averaging 170.7 centimetres and the 2001 cohort 169.3 centimetres. The data are drawn from about 719,000 self-reported heights gathered through national health surveys, local health services and the public health institute, and they cover people born and raised in the Netherlands.

That pause comes after a remarkable historical rise. Statistics Netherlands notes that men born in 1930 averaged 175.6 centimetres, meaning the 1980 cohort gained more than eight centimetres in half a century. Researchers have long linked that surge to better nutrition, improved healthcare and fewer childhood diseases, with the Dutch dairy-heavy diet often mentioned as a possible contributor. A study in Pediatric Research found that the average final height of Dutch boys reached 183.8 centimetres and girls 170.7 centimetres, and that there had been no significant increase since the late 1990s.

Immigration has also played a role in pulling down the national average, because newcomers from shorter populations and their Dutch-born children are included in the broader statistics. But the flattening is not explained by migration alone. Among Dutch-born women, the trend has actually turned downwards, suggesting the plateau is visible even without that demographic effect.

Researchers at the University of Groningen have also tested whether natural selection helped make the Dutch taller over time. Their study of more than 94,500 people born between 1935 and 1967 found that taller men tended to have more children, while women of average height had the most. Even so, the effect was small and could not account for either the rapid rise in height or the later stall. Broader international research has reached a similar conclusion: the Dutch remain among the tallest people in the world, but the era of uninterrupted gains appears to have ended.
