Is Deep South only region in US that still has homogenously English&Scottish descent people?

People of English ancestry traditionally predominate in every part of the Deep South except for southern Louisiana. As late as the 1980 census, people of English ancestry formed the largest single self-reported ancestry group in every single Southern State (other than Louisiana) by a large margin.[9] With regards to people who only reported a single ancestry group, in the 1980 census, 857,864 people in Alabama out of 2,165,653 people in the state at the time wrote "English" as their only ancestry making them 41% of the state at the time and the largest ethnic group at the time by a large margin. In Georgia, 1,132,184 out of 3,009,484 people in the state at the time identified "English" as their only ancestry, making them 37.62% of the state at the time. In Mississippi 496,481 people out of 1,551,364 people in the state at the time identified "English" as their only ancestry group making them 32.00 of the state at the time and the largest ethnic group by a large margin. In South Carolina 578,338 people out of 1,706,966 people in the state at the time identified "English" as their only ancestry group making them 33.88% of people in the state at the time and the largest ethnic group by a large margin. In Florida 1,132,033 people out of 5,159,967 identified "English" as their only ancestry group, making them 21.94%. In Louisiana people who identified "English" as their only ancestry were 440,558 people out of 2,319,259 people in the state at the time, making them 19.00% of people in the state and the second largest ethnicity or ancestry group in the state at the time, being outnumbered by people who wrote "French" as their only ancestry group, who respectively made up 480,711 people out of a 2,319,259 people in the state at the time or 20.73% of people in the state at the time. In Texas, 1,639,322 people identified "English" as their only ancestry group out of a total of 7,859,393 people in the state at the time, making them 20.86% of people in the state at the time and the largest ancestry group by a large margin. These figures to do not take into account people who wrote "English" as well as another ancestry group, and when factored together, people of who self identified as being of English descent, made up an even larger portion of southerners than is reported on the single ancestry responses.[10] As of 2003, the majority of African-Africans live in the Black Belt of the Deep South as well
