The Wapichan or Wapishana (or Wapisiana, Wapitxana, Vapidiana, Wapixana) are an indigenous group found in the Roraima area of southern Guyana and northern Brazil.
In 1984, the Brazilian National Foundation estimated that there were only 2,995 Wapishana in twenty Brazilian villages. There are no estimates of the number of Wapishana who live outside villages. According to a 1981 survey in Guyana, there were approximately 5,000 Wapishana in Southern Rupununi, southern area of Guyana bordering Brazil. In 1997 the Wapishana population was estimated to be between 10,000 and 11,000 people. According to Funasa's data for 2008, the Wapishana population totals around 7,000 individuals. For Guyana, the most recent estimate is about 6,000 people. In Brazil, Wapishana villages contain an average population of 150 inhabitants, while on the other hand the number of inhabitants is higher for villages in Guyana, which average around 500 inhabitants.
Currently the Wapishana are located in the State of Roraima, Brazil, northern and eastern Boa Vista, as well as in the southern Rupununi savannas of Guyana. In their villages, one can find ranches, settlements, small towns, and commercial developments of Brazilians. In Guyana, the Wapishana villages are located between the Tacutu, Rupununi, and Kwitaro rivers, bordering the Macushi territory in the Kanaku Mountains to the north, and extending as far as the Wai-Wai territory to the south. In Brazilian territory, in the north eastern portion of Roraima, the Wapishana villages are mostly located in the Serra da Lua (Moon Ridge) region between the Branco River and one of its affluent, the Tacutu. On the lower Uraricoera River, another affluent of the Branco, most of the villages contain a mixed population of Wapishana and Macushi.
Wapishana is classified as a member of the Arawak language family. Wapishana is the only remaining Arawakan language in the circum-Roraima area. The term Arawak is more generally used to refer to the Arawakan or Lokono languages spoken in Venezuela, Guyana, Suriname, French Guiana and in some of the Antilles Islands. Most Brazilian Wapishana often speak Portuguese, instead of Wapishana and many Guyanese Wapishana speak English in addition to Wapishana. Portuguese is the dominant language among the Wapishana who live in urban areas that are bilingual in Portuguese and Wapishana, especially among the younger generations. According to Migliazza, more than 80% of Wapishana can speak the national language with which they are in contact, Portuguese in Brazil or English in Guyana. Since someone can cross the border between the two countries so easily, it is common to find people who speak Portuguese and English, as well as the maternal language.
