 Based on a survey and census from 1992 it was found that approximately 23.6% of the population was illiterate.However, these percentages may have significantly changed due to Mr. President's Evo Morales Ayma's program "Yo Si Puedo" in 2006.The program sought to end illiteracy specially in rural areas, to help adults over 50 years old who predominantly spoke quechua and worked arduous jobs in the field.
