Alt text: Chart showing average height, but incorrectly scales the entire person instead of just the height, with the Netherlands as the tallest and Indonesians as the shortest. Bottom image is the Bane vs. Pink guy meme showing Bane as the Dutch and Pink guy as the Indonesians.
That’s hard to tell, because not everyone tracks data the same way.
The UK has a population that’s 72% British/Irish. The Netherlands has a population that’s 74% Dutch.
I figured it would be hard to determine statistically, but figured it was worth mentioning for consideration.
The 5 largest ethnic groups in the United States are White (Non-Hispanic) (58.2%), Black or African American (Non-Hispanic) (12%), Two+ (Hispanic) (6.84%), Other (Hispanic) (6.11%), and Asian (Non-Hispanic) (5.75%).
There are lots of factors that can influence height but about 80% of an individual’s height is determined by genetics and certain populations, like those in the Dinaric Alps (including parts of Eastern Europe), are predisposed to taller statures.
For example, Uganda is generally considered the most ethnically diverse country and the average male height there is 5’ 6.4" which is really close to the global average. Correlation by itself doesn’t equal causation but it’s a good place to start.
Genetic diversity obviously plays a role, and epigenetics matter a lot too. The abundance of food and quality of nutrition that we’ve had since WW2 in the Netherlands, combined with genetics that predispose, combine together.
But there is also a BIG difference between the racial stats the US keeps and the direct descendance stats the Netherlands keeps. If your family came from Ethiopia to the US in 1640 and has raised 12 generations of Americans, you’re “Black or African American”.
If your four grandparents are 30cm tall blue Smurfs, but both your parents were born in the Netherlands, you’re a native Dutch person in every Dutch statistic.
