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.

Variables collected Variables collectedTotal household income (ING_TOTAL); Deciles of Household income (DECILH)
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 coverageSelected Households of private dwellings in blocks (or sections) chosen from the sampling frame (excluding collective households). Minors who may have received income are included, these data being imputed to the head of household line.
Sector coverage Sector coverageAll economic sectors used in the classification CIIU4.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 Classification(s) used Classification(s) usedDeciles of household income
Estimation EstimationTotal income of decile (i) / Total income of households
Imputation ImputationFor the main income variables, a variant of the conditional-means procedure is used to search for and select donors. Qualitative variables (demand levels based on characteristics of income recipients) are mixed with geographical variables (areas of estimation). Failure or refusal to provide information considered for the purposes of this imputation has three a variables: 1. Labour income from the principal occupation (Income from Wages and Salaries, and Income from Self-employment) 2. Income from Retirement or Pension 3. Imputed Rent. For the variable of number of hours actually worked in the reference month, a substitution methodology is used, that is, the imputation of the hours actually worked is replaced with data reported by the same informant regarding hours normally worked.
Key statistical concept Key statistical conceptHousehold income: all income from all income sources, including income from work, income from property, and income from transfers. Deciles: refer to a division of the population of the study into ten groups of observations, which are ordered by a reference variable. In this case, the population of households is divided into ten groups ordered by per capita income of the household (based on total income of the household)
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 SPSS and CSV format.
Weights WeightsThe expansion factor consists of two parts: i. A theoretical factor, which is the inverse of the selection probabilities of the primary and secondary sampling units, and which includes an implicit non-response adjustment. ii. A post-stratification factor, which is the ratio of demographic totals projected to the middle month of the mobile quarter (based on the 2002 Population and Housing Census for sections or the more recent sample frame for blocks), versus the estimate of total number of persons based on the "theoretical factor". Population stocks or post- stratification are carried out without distinction of sex and age group.
Other Aspects Other Aspects Quality comments Quality comments Recommended uses and limitations Recommended uses and limitationsThe following criteria are recommended as reference for the analysis of results: I. If the number of cases is smaller than 60 or if the degrees of freedom are less than 9, the estimate is considered to be unreliable, regardless of the coefficient of variation's value. II. If the coefficient of variation is smaller than 15%, the estimate is considered to be good or precise, if and only if the frequency of cases is greater or equal than 60 and the degrees of freedom are greater or equal than 9. III. If the coefficient of variation is greater or equal than 15%, the estimate should be used with caution, if and only if the frequency of cases is greater or equal than 60 and the degrees of freedom are greater or equal than 9.

Households
The 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.
All economic sectors used in the classification CIIU4.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.
Selected Households of private dwellings in blocks (or sections) chosen from the sampling frame (excluding collective households). Minors who may have received income are included, these data being imputed to the head of household line.
