Continuous survey on a quarterly basis (Q1-2005 to Q1-2020) or quarterly/monthly basis (Q3-2020 forward). The logistics and timing for the visits to collect the information varies depending if households are located in the self-represented cities, urban complement, or rural areas. The survey includes a sociodemographic questionnaire for all household residents and an employment questionnaire for persons age 12 or older. Two types of employment questionnaires: basic (short) and extended (long), which are used in different quarters (see details here). The extended (long) questionnaire has 11 sections: labor force status, unemployment, job characteristics, employer characteristics, work schedule, income and health insurance, secondary employment, job search, work history, participation in government programs, and time use. The short form includes a subset of those sections.
