Periodicity PeriodicityAnnual
Reference period Reference periodReference month: month previous to the reference week of the ENE (the week, Monday to Sunday, before the survey)
Sampling SamplingSampling of the ENE has two stages and is probabilistic. The two stages refer to the First Stage Sampling Unit (UPE), which is the block (urban) or section (rural), and the Second Stage Sampling Unit (USE), which is the private occupied dwelling. Probabilistic means that the selection of the UPE in each stratum is proportional to the size of the unit in relation to the number of dwellings (USE) and that the probability of selection of the USE is equal for all dwellings within the UPE.
Unit of measure used Unit of measure usedPercentage
Variables collected Variables collectedIncome from principal occupation (ING_T_P)
Population & Scope Population & Scope Geographic coverage Geographic coverageThe population living in Chile, excluding collective housing. Also excluded, because of operational problems, are areas of difficult access (ADA) and blocks with seven or fewer dwellings.
Population coverage Population coverageThe entire population aged 15 and over, belonging to households of private dwellings selected in the chosen blocks (or sections) of the sampling frame (excluding collective households).
Sector coverage Sector coverageAll economic sectors used in the classification ISIC4.cl 2012, according to CAENES are covered. It should be noted that, for the Supplementary Survey of Income, the branch of economic activity refers to the sector of the economic unit, company, or business where the employed person works.

Concepts & Classifications Concepts & Classifications Aggregation & consolidation Aggregation & consolidationEducational level (ISCED) grouped into 7 categories: Never studied/Pre-school, Primary, Secondary, Technical, University, Graduate, Unknown level. Six age brackets: 15-24 years, 25-34 years, 35-44 years, 45-54 years, 55-64 years, 65 years and over. ICSE Occupational Categories: Employers, Own-account Workers, Wage earners of the private sector, Wage earners of the public sector, Domestic Service workers. Because unpaid family workers have no recorded income, ICSE does not include them in their classification.
Classification(s) used Classification(s) usedInternational Classification of Status in Employment (ICSE_93). International Standard Classification of Education (ISCED_97).
Estimation EstimationEmployed population of category (i) of variable (j) below the fiftieth percentile of income / Total of employed population below the fiftieth percentile of income
Imputation ImputationFor the main income variables, a variant of the conditional means imputation is used for the search and selection of donors. Qualitative variables (demand levels based on characteristics of income recipients) are mixed with geographic variables (areas of estimation). The omissions or refusals to deliver information that are considered for the purposes of this imputation are: Labor income from principal occupation (Income from Wages and Salaries, and Income from Self-Employment). For the variable of the number of hours actually worked in the reference month, a substitution methodology is used, that is, the imputation of the hours actually worked using data reported by the same informant in terms of hours usually worked.
Key statistical concept Key statistical conceptIncome from occupation: all income from current principal occupation that was received in the in the reference period of the survey.
Dissemination format(s) Dissemination format(s)Dissemination has three formats: 1. Institutional webpage for the publication of official tabulations (2010-2017), databases, and related documents. 2. PDF documents related to the analysis of specific profiles of income. 3. Micro-databases in STATA, SPSS and CSV format.
Weights WeightsAccording to the sample design, the calculation of the expansion factor is made up of two parts that account for each of the selection stages, that is, a weighting that accounts for the selection of first-stage units (blocks and sections ); and another, which accounts for the selection of second-stage units (dwellings) and is calculated as the inverse of the probabilities of selection of said sampling units. The resulting factor (formed by both selection stages) is adjusted by information annexed to the survey, which accounts for the population stocks obtained from the Population and Housing Census of 2017. This adjustment corresponds to the calibration by the Raking method.
