Speaker number: 1,500-2,000 in Colombia.
Ethnic population: Approximately 11,444 in Colombia and Brazil.
Welch and West (2000) mention the fact that there are many more speakers of Tucano than the number of 1,500–2,000 that they give for the ethnic group, since it is used as a lingua franca in the Paca and Papurı rivers region.
