Yes. But they have genetically different heights. And that's relevant too.
I am absolutely not 'blaming immigrants' for anything. I am saying there is a shifting demographic pattern occurring at some speed. This is a neutral thing - it is neither good not bad - but it is observable.
The UK and the Netherlands have significant shared history and genealogy - but changing patterns of migration for both countries mean there is a divergent genetic pattern happening.
I think the comment about socioeconomics is relevant with regards to immigration too. Why? Because we know recent immigrants are more likely to be lower status economically.

See the percentage of people living in the most deprived 10% of neighbourhoods by ethnicity:
What REALLY sticks out is over 31% of people of Pakistani ethnicity live in these neighborhoods and over 19% of Bangladeshi ethnicity. This compares to 9% of White British.
Or another figure from the Joseph Rowntree Foundation:
The income poverty rate varies substantially between ethnic groups: Bangladeshis (65%),
Pakistanis (55%) and black Africans (45%) have the highest rates; black Caribbeans (30%),
Indians (25%), white Other (25%) and white British (20%) have the lowest rates.
So we have a population which genetically looks predisposed to being shorter also living in the most deprived areas and rated at the most at risk of poverty. So they are less likely to reach their maximum height potential which is shorter to begin with.
Also curiosly comments about milk consumption may also have some merit. The Netherlands has one of the heightest levels of milk consumption per person in the world.

And that will affect the most deprived areas first.
