This.
I thought the article was illiterate.
- In 2021, 28.8% of live births were to non-UK-born women; this is a decrease from 29.3% in 2020.
- The total fertility rate (TFR) increased for UK-born women to 1.54 children per woman; the TFR for non-UK-born women remained at 2.03 children per woman.
- In 2021, Pakistan remained the most common country of birth for non-UK-born fathers; Romania was the most common country of birth for non-UK-born mothers, and this was up from second in 2020.
- Albania moved into the top ten most common countries of birth for both non-UK-born mothers and non-UK-born fathers for the first time.

Compare this with the Netherlands. I couldn't find corresponding data but I could find info on country of origin of people born in the Netherlands with one or both foreign born parents:
On 1 January 2021, the Netherlands had 15 million residents born in the Netherlands (Table 5.1.1), 2 million of whom are children of migrants (formerly referred to as second-generation migrants). They have one or two parents who were born abroad. Just over half (1.1 million) of them have one foreign-born and one Netherlands-born parent, just under half (890,000) have two foreign-born parents. Almost 2.5 million residents of the Netherlands are migrants, i.e. people who were born abroad (formerly referred to as first-generation migrants). The vast majority of this group have two parents who were born abroad (2.2 million).
Of the 17.5 million people who lived in the Netherlands on 1 January 2021, 14.0 percent were not born in the Netherlands (migrants). Another 11.4 percent of the population were born in the Netherlands as the child of (a) migrant(s) (with at least one foreign-born parent).
On 1 January 2021, nearly 2.5 million residents of the Netherlands were born abroad. Under the new classification, two-thirds of them (1.6 million people) have their origins Outside Europe (Table 5.2.1, Figure 5.2.2). Among the traditional countries of migration, the group born in Turkey is the largest (201,000), followed by migrants born in Suriname (178,000) and Morocco (173,000). The Netherlands is also home to a relatively large group of migrants born in other Asian countries (497,000 people).
Of the 890,000 residents born in the Netherlands with two foreign-born parents, by far the largest group comes from Outside Europe. One-fifth (188,000) are of Moroccan origin, and a slightly lower number (164,000) are of Turkish origin.
And general speaking Indian nationals are the largest foreign born group in the UK:
In 2020/21 there were approximately 896,000 Indian nationals living in the United Kingdom, the highest non-British population at this time. Polish was the second largest nationality at 682,000.
Put simply we know that India has one of the shortest average heights in the world, which have a high percentage of the population who were of Indian origin. Pakistan was the country of origin for the most babies with a foreign born father in 2021. Again Pakistan is right at the born for average height by country.
Our changing demographic and the difference with the Netherlands who don't seem to have either India or Pakistan featuring in their most common foreign origins.
So genetically both countries are diverging. And this matters.
But when I've seen this data reported today there's been a distinct lack of comment on these genetic differences.
