I’d be curious to compare against those that immigrated here and became USA citizens.

The Federal Statistical Office (Destatis) reports that 9,782 (3.6%) of the 270,294 Germans who left the country in 2019 moved to the United States. =
The only countries chosen by more Germans were Switzerland (16,340) and Austria (11,904).
and for Denmark
In 2022, the most common destination for people emigrating from Denmark was the United States. nearly 4,700 people emigrated to the U.S., followed by the Scandinavian neighbor Norway and southern neighbor Germany. Denmark only borders Germany, except for a bridge via the Öresund strait to Sweden. Moreover, 9,500 of the people emigrating from Denmark in 2022 did not state their destination country.
So about 10% of emigrants from Denmark chose the USA
And about 6,800 Ozzies migrate to the USA each year
