Estimates, identity and relationship between language use and self-ascription

This work studies the differences that arise when self-identification or the use of the indigenous language is used in the estimation of the indigenous population. As a result of the analysis of official information, it is concluded that the increase in schooling at home and the receipt of income from relatives living abroad, discourages people from indicating the use of the language and self-registering. On the other hand, it is found that people who receive support from the government have greater incentives to declare the use of the language and self-enroll. Finally, it is shown that self-enrollment and use of the indigenous language are not the same variables and therefore cannot be used as an equivalent criterion for the realization of public policy. It is statistically demonstrated that people who speak the indigenous language constitute a subset of people who self-describe as indigenous.
