At-risk-of-poverty rate – share of persons with an equivalised annual disposable income lower than the at-risk-of-poverty threshold.
At-risk-of-poverty threshold – 60% of the median equivalised annual disposable income of household members.
Disposable (net) income – a sum of income from wage labour and self-employment, property income, social transfers, regular inter-household cash transfers received and receipts for tax adjustment of which inter-household cash transfers paid, taxes on wealth and repayments for tax adjustment have been subtracted.
Equalised income – total household income, which is divided by a sum of equivalence scales of all household members.
Household – a group of people who live in a common dwelling (at the same address), share joint financial and/or food resources and whose members consider themselves to belong to the same household. A household may also consist of one member only.
Income quintile – one fifth of the population based on equivalised annual disposable income. The first or the lowest quintile contains one fifth of the population receiving the lowest income, the second quintile contains the next fifth and so on.

To assure the quality of processes and products, Statistics Estonia applies the EFQM Excellence Model, the European Statistics Code of Practice and the Quality Assurance Framework of the European Statistical System (ESS QAF). Statistics Estonia is also guided by the requirements in § 7. “Principles and quality criteria of producing official statistics” of the Official Statistics Act.
11.2. Quality assessment Overall assessment of data quality, based on standard quality criteria.
Statistics Estonia performs all statistical activities according to an international model (Generic Statistical Business Process Model – GSBPM). According to the GSBPM, the final phase of statistical activities is overall evaluation using information gathered in each phase or sub-process; this information can take many forms, including feedback from users, process metadata, system metrics and suggestions from employees. This information is used to prepare the evaluation report which outlines all the quality problems related to the specific statistical activity and serves as input for improvement actions.
Standardised output has been achieved through the definition of specific formats (list and description of output variables; data formats) and the determination of fixed deadlines for data transmission.
12.1. User needs Description of users and their respective needs with respect to the statistical data.
Ministry of Social Affairs
The main users of ESS (EU-SILC) are:
- European Union institutions, government authorities (in Estonia, mostly the Ministry of Social Affairs – social protection and social inclusion issues), international organisations (e.g. OECD, UNICEF);
- annual yearbooks and other publications (incl. analytical compilations) of Statistics Estonia and Eurostat;
- researchers who have access to microdata;
- end users (consumers), incl. the media, who are interested in the statistics on living conditions, incomes and social inclusion in Estonia and the European Union.
Users’ suggestions and information about taking these into account are available on the website of Statistics Estonia at https://www.stat.ee/statistikatood.
12.2. User satisfaction Measures to determine user satisfaction.
Since 1996, Statistics Estonia has conducted reputation and user satisfaction surveys.
All results are available on the website at https://www.stat.ee/user-surveys.
12.3. Completeness The extent to which all statistics that are needed are available.
The data are complete and in compliance with the data composition requirements of EU-SILC regulation of the European Commission.
13. Accuracy and reliability Accuracy: closeness of computations or estimates to the exact or true values that the statistics were intended to measure.
13.1. Overall accuracy Assessment of accuracy, linked to a certain data set or domain, which is summarising the various components.
The accuracy of source data is monitored by assessing the methodological soundness of data sources and the adherence to the methodological recommendations.
The type of survey and the data collection methods ensure sufficient coverage and timeliness.
13.2. Sampling error That part of the difference between a population value and an estimate thereof, derived from a random sample, which is due to the fact that only a subset of the population is enumerated.
Sampling error estimates are calculated for all indicators found, but these are published only for more important indicators.
For more complicated survey designs, such as the Estonian Social Survey (ESS), ordinary statistical assumptions about independent and identical distribution of variables cannot be taken as basis. In the case of Laeken indicators, their nonlinearity also makes calculation of standard error more complicated. Additionally, it must be kept in mind that ordinary rules for calculating standard errors have been developed for samples without replacement. Concerning the ESS design, a sample with replacement is used at the level of households, because every household occurs in the sample frame with all its members.
Therefore, a two-step procedure is used for calculating standard errors for Laeken indicators. At first, the indicators are linearized by using linearization procedures developed by Eurostat. Then, the standard error is computed for the total sum of obtained new variable as a standard error of the respective indicator. The program Bascula is used for computing standard errors.
The standard errors are computed by resampling method; a number of sub-samples are taken from the initial sample and the standard errors are computed based on the variability of sub-sample estimates.
13.3. Non-sampling error Error in survey estimates which cannot be attributed to sampling fluctuations.
Although a person has the obligation to ensure correctness of residential address in the population register, there is some under-coverage of persons and households there. Assuming that all permanent residents of Estonia are registered in the Population Register and considering the share of inaccurate addresses in the Population Register, the rate of under-coverage among households is no more than 1–1.5%. The overall response rate is 61% for households interviewed for the first time and 88% for households interviewed for at least the second time. The detailed response rates are published in the Statistical Database.
Measurement errors may be caused by the questionnaire (wording of questions, questionnaire structure), respondents, interviewers and the data collection method. It is not possible to prevent all this type of measurement errors in social surveys, but Statistics Estonia has tried to limit their amount as much as possible.
The data are checked in three stages: initial check upon data entry during the interview (on the laptop), secondary check of newly received data at the office, and finally data cleaning.
The initial logic checks in the entry program are continually improved, which has reduced the number of errors during data entry.
The extreme values of all income components and total income are checked and handled separately.
14. Timeliness and punctuality
14.1. Timeliness Length of time between data availability and the event or phenomenon they describe.

14.2. Punctuality Time lag between the actual delivery of the data and the target date when it should have been delivered.
The data have been published at the time announced in the release calendar.
15. Coherence and comparability
15.1. Comparability - geographical The extent to which statistics are comparable between geographical areas.
The data are comparable with the data of other European Union countries.
15.2. Comparability - over time The extent to which statistics are comparable or reconcilable over time.
The data are comparable over time.

15.4. Coherence - internal The extent to which statistics are consistent within a given data set.
The outputs of the statistical activity are coherent.
17.1. Data revision - policy Policy aimed at ensuring the transparency of disseminated data, whereby preliminary data are compiled that are later revised.
The data revision policy and notification of corrections are described in the dissemination policy of Statistics Estonia at https://www.stat.ee/dissemination-policy.
17.2. Data revision - practice Information on the data revision practice.
18. Statistical processing
18.1. Source data Characteristics and components of the raw statistical data used for compiling statistical aggregates.
The population consists of all private households whose usual place of residence is in Estonia and the members of these households who do not live in institutions (children’s homes, care homes, monasteries, convents, prisons, etc.). About 1% of the population of Estonia is excluded from the survey.
The sample includes 7,400 households. Systematic stratified random sampling is used. The stratification is based on place of residence. The 15 counties and Tallinn city are divided into four strata by population size: I – Tallinn; II – four bigger counties (Harju (excl. Tallinn), Ida-Viru, Pärnu and Tartu counties); III – ten smaller counties (Jõgeva, Järva, Lääne, Lääne-Viru, Põlva, Rapla, Saare, Valga, Viljandi and Võru counties); IV – Hiiu county.
The following data are received from the Estonian Tax and Customs Board: data on income tax returns for resident natural persons (form A), business income of resident natural person (form E), declaration of income and social tax, unemployment insurance premiums and contributions to mandatory funded pension (form TSD); and unemployment insurance benefits and taxes paid on income. The following data for the year 2013 according to the sampling in 2014 are received from the Social Insurance Board: amount and time of payment of benefits, pensions and allowances (by type) paid on the basis of the State Pension Insurance Act, State Family Benefits Act, Parental Benefit Act and Social Benefits for Disabled Persons Act; data on percentage of loss of capacity for work (20, 30, etc. until 100) and on degree of disability (moderate, severe, profound); data on old-age pension, pension for incapacity for work, parental benefits, child allowances and maintenance allowance. The following data for the year 2013 according to the sampling in 2014 are received from the Estonian Health Insurance Fund: amount of benefits for temporary incapacity for work, income tax withheld, number of calendar days and type of benefit; and delivery records. The data received from the Estonian Tax and Customs Board, the register of registered unemployed persons and jobseekers and labour market services, State Pension Insurance Register and health insurance database are used to check the quality of the collected data regarding income. Starting from 2013, the following data from registers are used: old-age pension, pension for incapacity for work, parental benefits, child allowances, maintenance allowance (from the Social Insurance Board); unemployment insurance benefits and taxes paid on income (from the Estonian Tax and Customs Board); delivery records (from the Estonian Health Insurance Fund).
DATA FROM OTHER STATISTICAL ACTIVITIES
18.2. Frequency of data collection Frequency with which the source data are collected.
18.3. Data collection Systematic process of gathering data for official statistics.
Data are collected from individuals. The methods used for collecting the data include a personal interview (CAPI), in the case of recurring one-member households a telephone interview (CATI) or a web interview (CAWI), which the respondents complete independently. The interviews are conducted by Statistics Estonia's telephone interviewers with relevant training. The Survey Fieldwork Information System is used to manage and monitor data collection. The questionnaires have been designed to be filled in electronically by the respondent. The information related to data submission is available on Statistics Estonia's website at https://www.stat.ee/11757.
The data are collected with the official statistics questionnaires “Estonian Social Survey. Household questionnaire” and “Estonian Social Survey. Personal questionnaire”.
18.4. Data validation Process of monitoring the results of data compilation and ensuring the quality of statistical results.
Arithmetic and qualitative controls are used in the validation process, including comparison with other data. Before data dissemination, the internal coherence of the data is checked.
18.5. Data compilation Operations performed on data to derive new information according to a given set of rules.
In the case of missing or unreliable data, estimate imputation based on established regulations will be used. According to the regulation of the European Commission, all missing values of income variables should be imputed. As a rule, statistical imputation is the method used for that.
In case of within-household non-response, the persons who have not responded are imputed by using a person, characterized by similar variables, who is selected from among the responded persons by using the nearest neighbour method.
Variables and statistical units which were not collected but which are necessary for producing the output are calculated. New variables are calculated by applying arithmetic conversion to already existing variables. This may be done repeatedly, the derived variable may, in turn, be based on previously derived new variables.
For statistical units weights are calculated, which are used to expand the data of the sample survey to the total population.
The weights are calculated on the basis of design weights derived from inclusion probabilities. The weights, which are first adjusted to compensate for the bias caused by non-response and then calibrated to the population data, are used in calculating the final data. The basis of the calibration is the distribution of the population of Estonia by sex and age group and county on the 1st of January according to demographic data.
Microdata are aggregated to the level necessary for analysis. This includes summation of data according to the classification and calculating various statistical measures, e.g. average, median, dispersion, etc. The collected data are converted into statistical output. This includes calculating additional variables.
18.6. Adjustment The set of procedures employed to modify statistical data to enable it to conform to national or international standards or to address data quality differences when compiling specific data sets.
