Louisiana is a state located in the southern region of the United States of America. Louisiana is the 31st most extensive and the 25th most populous of the 50 United States. Its capital is Baton Rouge and largest city is New Orleans. Louisiana is the only state in the U.S. with political subdivisions termed parishes, which are local governments equivalent to counties. The largest parish by population is East Baton Rouge Parish, and the largest by land area is Cameron Parish.
Some Louisiana urban environments have a multicultural, multilingual heritage, being so strongly influenced by an admixture of 18th century French, Spanish, Native American (Indian) and African cultures that they are considered to be somewhat exceptional in the U.S. Before the American influx and statehood at the beginning of the 19th century, the territory of current Louisiana State had been a Spanish and French colony. In addition, the pattern of development included importing numerous African slaves in the 18th century, with many from the same region of West Africa, thus concentrating their culture.
 Transportation
In March 2011, Louisiana ranked as the second bottom "Worst" state (next to number 50 Kentucky), in the American State Litter Scorecard. The Pelican State suffers from an overall poor effectiveness and quality of its statewide public space cleanliness (primarily from roadway and adjacent litter/debris)--in state and related eradication standards.
The Louisiana Department of Transportation and Development is the state government organization in charge of maintaining public transportation, roadways, bridges, canals, select levees, floodplain management, port facilities, commercial vehicles, and aviation which includes 69 airports.
The Intracoastal Waterway is an important means of transporting commercial goods such as petroleum and petroleum products, agricultural produce, building materials and manufactured goods.
In 2011, Louisiana ranked among the five deadliest states for debris/litter –caused vehicle accidents per total number of registered vehicles and population size. Figures derived from  the NTSHA show at least 25 persons in Louisiana were killed each year in motor vehicle collisions with non-fixed objects, including debris, dumped litter, animals and their carcasses.
 Languages
Louisiana has a unique linguistic culture, owing to its French and Spanish heritage. According to the 2000 census, among persons five years old and older, 90.8% of Louisiana residents speak only English (99% total speak English) and 4.7% speak French at home (7% total speak French). Other minority languages are Spanish, which is spoken by 2.5% of the population; Vietnamese, by 0.6%; and German, by 0.2%. Although state law recognizes the usage of English and French in certain circumstances, the Louisiana State Constitution does not declare any "de jure official language or languages". Currently the "de facto administrative languages" of the Louisiana State Government are English and French.
There are several unique dialects of French, Creole, and English spoken in Louisiana. There are two unique dialects of the French language: Cajun French (predominant after the Great Upheaval of Acadians from Canada) and Colonial French. For the Creole language, there is Louisiana Creole French. There are also two unique dialects of the English language: Cajun English, a French-influenced variety of English, and what is informally known as Yat, which resembles the New York City dialect, particularly that of historical Brooklyn, as both accents were influenced by large communities of immigrant Irish and Italian, but the Yat dialect was also influenced by French and Spanish.
Colonial French was the predominant language of Louisiana during the French colonial period and was spoken primarily by the white settlers; the black/creole population spoke mostly creole. Cajun French was only introduced in Louisiana after the Great Upheaval of Acadians from Canada during 1710-1763. The Cajun people and culture (hence the Cajun language as well) did not appear immediately but was rather a slow evolution from the original Acadian culture with influences from local cultures. English and its associated dialects became predominant only after the Louisiana Purchase and even then it still retained some French influences as seen with Cajun English. Cajun French and Colonial French have somewhat merged since English took over.
