South Carolina adopted the English language is the official language of the State of South Carolina in 1987
Since 1981, 25 states have adopted various forms of Official English legislation, in addition to four that had already done so. Subtracting Hawai'i (which is officially bilingual) and Alaska (whose English-only initiative has been declared unconstitutional) leaves a total of 27 states with active Official English laws. These measures are unrelated, however, to the process of amending the U.S. Constitution.
5.2 percent of this state's residents speak a language other than English. The most common of these languages are Spanish, French, German, and Tagalog (Philipino). The portion of South Carolinians who speak little or no English has more than tripled since 1990.
The law designating the English as the official South Carolina state language is found in the South Carolina Code of Laws, Title 1, Chapter 1, Article 9, Section 1-1-696 thru 1-1-698.
