Out of the 57.9%, the largest groups were 12.0% German (2,212,391), 10.7% Irish (1,979,058), 8.8% English (1,629,832), 6.6% Italian (1,215,242), 2.8% Polish (511,229), and 2.7% French (504,641). White Americans of all European backgrounds are present in all areas of the state. In 1970, non-Hispanic whites were nearly 80% of Florida's population. Those of English and Irish ancestry are present in large numbers in all the urban/suburban areas across the state.
