Depends what you mean. Vermont has the highest population of white people @ 95.6%. But since California has the highest population and 42.8% are white, that's over 15 million white people. So... the most white people in one state would be California.

There are a lot of nations where the "white" people are the majority, though bear in
mind that Southern Europeans: Spain, Italy, Greece, Southern France, etc. have
different skin tones than Northern Europeans.
So here's what I can think of:
Australia
Canada
Entire Europe including Russia
U.S.
and
Some Central and South American Countries like Puerto Rico and Argentina.
Various small nations around the world that has once been an European colony.
California. About 85% of California is of Caucasian decent, meaning about 32,300,000/38,000,000 Californians are Caucasian. (Caucasian includes whites, hispanics, middle easterns, and indians)
California has the most white people in one state. Vermont has the highest percentage population of white people @ 95.6%. California has the highest population and 42.8% are white; that's over 15 million white people. If White Hispanics and Latinos are included, this increases to 23 million white people.
Vermont has the largest percentage of whites at about 95.3%, while California has the most whites total at about 22,000,000.
California has the largest number of Caucasians, around 28,500,000 in total.

Alabama

White Europeans are people, so they are one and the same; the title European is to state which part of the world they originate from which would be Europe.
