When the answer is "yes", proceed to question 14 "Name of indigenous language". If the answer is "no", pass to question 16 "Understand indigenous language". If the respondent answers, that "he/she speak a little", "I do not speak fluent, but I understand it", "I speak, but I do not write" considers that the person does speak an indigenous language. Also record that the person speaks an indigenous language even when it is not used regularly. For question 14, records the name of the indigenous language as heard, without using abbreviations.
[Figures are omitted]
Make clarifications particularly for the following languages: if the language is Chontal, ask if it is from Oaxaca or Tabasco; if the language is Amuzgo, asks if it is from Oaxaca or Guerrero; and if the language is Tepehuano, ask if it is from Chihuahua or Durango.
If the answer is "the language spoken in the region", "the language spoken by my parents" or answers that do not specify the language, ask for the name of the language and write it. If the informant does not know the name of the language, write the textual answer.
When the informant does not know the answer, write "does not know".
For question 15, if the answer is "a little", "almost nothing", "some words", among others, consider that he/she does not speak Spanish. If the person speaks Spanish, record that he/she does speak Spanish even though the person does not speak it regularly.
When you finish with question 15 "Speak Spanish", go to question 17 "School attendance".
