The objective is to capture the general development of wage income across time. Average income is calculated and multiplied by the deflator (whose calculation is based on the CPI) to control for changes in consumer prices across time (values of October of the last year of calculation).

Sampling 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.

For 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.

Income from work: total income from current principal activity, received in the reference month of the survey. Real income: the adjustment in income in consideration of inflation as determined by the Consumer Price Index (CPI).

The 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.

The 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.

Statistical Agendahttp://www.ine.cl/inicio/agendaestadistica?len=en
Statistical population

Employed population

Geographic coverage

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.

Sector coverage

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.

Population coverage

The 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).

Key statistical concept

Income from work: total income from current principal activity, received in the reference month of the survey. Real income: the adjustment in income in consideration of inflation as determined by the Consumer Price Index (CPI).

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.
