Roads in the US have been paved with materials that include asphalt/bitumen since at least 1870, when a street in front of the Newark, NJ City Hall was paved. In many cases, these early pavings were made from naturally occurring "bituminous rock", such as at Ritchie Mines in Macfarlan in Ritchie County, West Virginia from 1852 to 1873. In 1876, asphalt-based paving was used to pave Pennsylvania Avenue in Washington, DC, in time for the celebration of the national centennial. Asphalt/bitumen was also used for flooring, paving and waterproofing of baths and swimming pools during the early 20th century, following similar trends in Europe.

By the 2000 census, demographic changes including the end to slavery, immigration from Europe and Asia, assimilation of multiracial persons, and other factors resulted in a population in which 6.2% of the population identified as black, 40% as pardo, and 55% as white. Essentially most of the black population was absorbed into the multi-racial category by intermixing. A 2007 genetic study found that at least 29% of the middle-class, white Brazilian population had some recent (since 1822 and the end of the colonial period) African ancestry.

Ah, so.. 40%

The 1998 edition of Guinness Book of World Records stated: "No female artist has sold more records than Madonna around the world". In 1999 Madonna signed to play a violin teacher in the film Music of the Heart but left the project, citing "creative differences" with director Wes Craven. She recorded the single "Beautiful Stranger" for the 1999 film Austin Powers: The Spy Who Shagged Me. It reached number 19 on the Hot 100 solely on radio airplay. Madonna won a Grammy Award for "Best Song Written for a Motion Picture, Television or Other Visual Media".
