Supplementary Survey of Income (ESI)

The Supplementary Survey of Income (ESI) is a complementary module within the National Employment Survey (ENE). The ESI is conducted once a year during the October–December quarter in all regions of Chile, both in urban and rural areas. Its objective is to characterize the labour income of people classified as employed in the ENE and their income from occupations other than the main job, both at the national and regional levels.

As of the 2023 version of the ESI, information on income indicators was moved from the INE.STAT platform to the Labour Market Information System (SIMEL)..
