In 1960, non-Hispanic whites represented 80% of Miami-Dade county's population. In 1970, the Census Bureau reported Miami's population as 45.3% Hispanic, 32.9% non-Hispanic White, and 22.7% Black. Miami's explosive population growth has been driven by internal migration from other parts of the country, primarily up until the 1980s, as well as by immigration, primarily from the 1960s to the 1990s. Today, immigration to Miami has slowed significantly and Miami's growth today is attributed greatly to its fast urbanization and high-rise construction, which has increased its inner city neighborhood population densities, such as in Downtown, Brickell, and Edgewater, where one area in Downtown alone saw a 2,069% increase in population in the 2010 Census. Miami is regarded as more of a multicultural mosaic, than it is a melting pot, with residents still maintaining much of, or some of their cultural traits. The overall culture of Miami is heavily influenced by its large population of Hispanics and blacks mainly from the Caribbean islands.

What percentage of the Miami population in 1970 was black?
Answer: 22.7

Originally based on the English alphabet, ASCII encodes 128 specified characters into seven-bit integers as shown by the ASCII chart on the right. The characters encoded are numbers 0 to 9, lowercase letters a to z, uppercase letters A to Z, basic punctuation symbols, control codes that originated with Teletype machines, and a space. For example, lowercase j would become binary 1101010 and decimal 106. ASCII includes definitions for 128 characters: 33 are non-printing control characters (many now obsolete) that affect how text and space are processed and 95 printable characters, including the space (which is considered an invisible graphic:223).

What is the ASCII based on?
Answer: English alphabet
