African Americans constitute the third largest racial and ethnic group in the United States (after White Americans and Hispanic and Latino Americans). Most African Americans are descendants of enslaved peoples within the boundaries of the present United States. On average, African Americans are of West/Central African and European descent, and some also have Native American ancestry. According to U. S. Census Bureau data, African immigrants generally do not self-identify as African American. The overwhelming majority of African immigrants identify instead with their own respective ethnicities (≈95%). Immigrants from some Caribbean, Central American and South American nations and their descendants may or may not also self-identify with the term.
In the United States, this form of housing goes back to the early years of cars and motorized highway travel. It was derived from the travel trailer (often referred to during the early years as “house trailers” or “trailer coaches”), a small unit with wheels attached permanently, often used for camping or extended travel.
The original rationale for this type of housing was its mobility. Units were initially marketed primarily to people whose lifestyle required mobility. However, beginning in the 1950s, the homes began to be marketed primarily as an inexpensive form of housing designed to be set up and left in a location for long periods of time, or even permanently installed with a masonry foundation. Previously, units had been eight feet or less in width, but in 1956, the 10-foot (3 m) wide home (“ten-wide”) was introduced, along with the new term “mobile home”.
