The 2022 National Socioeconomic Characterization Survey (CASEN 2022) is representative at the national and regional levels (16 regions of the country), as well as in urban and rural geographic areas. However, communes are not a study domain, so estimates at that level may have low precision and are not recommended.
To provide information at the communitarian level, the Ministry of Social Development and Family applies the Small Area Estimation (SAE) methodology, which has been used to obtain communitarian estimates for the income poverty rate since 2011 and, since 2015, communitarian estimates for the multidimensional poverty index.
The methodology was updated between 2019 and 2020, with support from ECLAC. For more information on this update, we recommend reviewing the methodological report available at:

The estimates of communal income poverty and the communal multidimensional poverty index based on Casen 2022 use the methodology updated in 2020. Therefore, this document provides an understanding of the main methodological aspects currently being used in the application of the SAE methodology.
