I asked Chat GPT and got some extensive results. (all numbers are approximates)
I had once suspected that a US merger with Canada might be a White nationalist plot, but the raw numbers don’t serve such a purpose, by themselves.
For example, the combined numbers of US Indigenous (4m) and Canadian First Nations (2m) results in 6 million people and an even higher proportion in the merged nation(1.6%) than in the US (1.4%) and Canada (1%) respectively.
Likewise, The US-Canada Black population would now have 49 million people, combining US Blacks (46 million) and Canadian Blacks (1.7m). The new combined percentage would be 13% of the merged total. That’s a slight drop from 13.6% for US Blacks, but a dramatic increase for Black Canadians, who currently represent only 4% of Canada’s population.
The White population of the merged nation would have the biggest gains in practical terms. Non-Hispanic US Whites, now at 197m (50-58%) and Canadian Whites, now at 27m (67.4%) would combine for a new total of 224 million people, representing 59% of the new US-Canada merged population of 375 million people. This would slow down the process of Whites losing their majority in both countries, but probably would not reverse it. However, the more even distribution of of Whites, both geographically and economically, would enable them to hold onto a disproportionate amount of influence in the new, larger nation.
The Hispanic/Latino population would remain about the same (as there are few Latinos in Canada), but its proportion would drop from 20% in the US to 17.3% in the merged US-Canada.
If the United States and Canada were to merge, the combined population would be approximately 375 million people. To estimate the racial and ethnic composition of this unified population, we can analyze the demographics of each country as of 2025.

Estimated Combined Demographics:
By weighting the populations of each country, we can approximate the racial and ethnic breakdown of the merged nation:
These figures are rough estimates, as the racial and ethnic categories used by the United States and Canada differ, and the dynamics of a merged population could lead to shifts in these demographics over time.

Redo this, but separate Hispanic Whites from non-Hispanic Whites
Here's a revised breakdown with Hispanic Whites separated from non-Hispanic Whites for the hypothetical merged United States and Canada (approx. 375 million people).
