However, the English Americans and British Americans demography is considered a serious under-count as they tend to self-report and identify as simply "Americans" (since the introduction of a new "American" category in the 1990 census) due to the length of time they have inhabited America.
With a total population exceeded only by those of China and India, the United States is also characterized by an extraordinary diversity in ethnic and racial ancestry.
In America, you can find deeply religious and conservative communities, progressive modern cities, dramatic mountain landscapes, and arid deserts. Even so, when taken together, it's arguable that a uniquely American lifestyle or character has developed over time that many Americans will recognize.
