11. Quality management Systems and frameworks in place within an organisation to manage the quality of statistical products and processes.

11.1. Quality assurance All systematic activities implemented that can be demonstrated to provide confidence that the processes will fulfil the requirements for the statistical output.

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.

12. Relevance The degree to which statistical information meet current and potential needs of the users.

12.1. User needs Description of users and their respective needs with respect to the statistical data.

Ministry of Social Affairs

State authorities – for analysing the current situation, developing action plans and policies

Local governments – for analysing the current situation, developing action plans

Research and educational institutions, libraries – for doing research and analyses, disseminating statistical information

Media – for disseminating statistical information to the general public

Companies, associations, foundations – for analysing the current situation, determining trends and making projections

International organisations and Eurostat – for assessing and analysing the situation in Estonia, developing international policies

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.

13. Accuracy and reliability Accuracy: closeness of computations or estimates to the exact or true values that the statistics were intended to measure.
Reliability: closeness of the initial estimated value to the subsequent estimated value.

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.

The error due to probability sampling is estimated.

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 in the register. Assuming that all persons living permanently in Estonia are registered in the Population Register and considering the amount of imprecise addresses in the Population Register, the under-coverage of households may be at most 1–1.5%.

Measurement errors can stem from the questionnaire (wording of questions, design, etc.), the respondents, the interviewers and the data collection method. While it is impossible to avoid this type of errors completely in social surveys, steps have been taken in Statistics Estonia to reduce them as much as possible.

Data checking is done in three stages: preliminary data entry checking in the laptop during the interview, secondary checking of newly received data in the office and finally data cleaning.

Data entry mistakes have decreased thanks to the continuing development of primary logical checks in the data entry program.

14. Timeliness and punctuality

14.1. Timeliness Length of time between data availability and the event or phenomenon they describe.

The data are published 8 months (240 days) after the end of the reporting year (T + 240).

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 calender.

15. Coherence and comparability

15.1. Comparability - geographical The extent to which statistics are comparable between geographical areas.

The time use survey is based on the international cooperation agreement (Gentleman’s Agreement) and the survey handbook issued by Eurostat. When comparing the data with data from other countries, the differences in data collection methodology, classifications and survey periods should be taken into account. Starting in 2030, the survey is planned to be conducted on the basis of the Framework Regulation for Social Statistics (Integrated European Social Statistics — IESS), which should improve the international comparability of the data.

15.2. Comparability - over time The extent to which statistics are comparable or reconcilable over time.

The time series data are comparable in the main activity groups of the activity coding list for harmonised European time use surveys. Due to the change in the classification, the data are not comparable in all lower level activities.

15.3. Coherence - cross domain The extent to which statistics are reconcilable with those obtained through other data sources or statistical domains.

Not applicable

15.4. Coherence - internal The extent to which statistics are consistent within a given data set.

The internal consistency of the data is ensured by the use of a common methodology for data collection and data aggregation.

16. Cost and burden Cost associated with the collection and production of a statistical product and burden on respondents.

Cost of statistical activity 70 thousand euros (data for 2018)

17. Data revision Any change in a value of a statistic released to the public.

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.

Not applicable

18. Statistical processing

18.1. Source data Characteristics and components of the raw statistical data used for compiling statistical aggregates.


The population consists of 1,212,00 objects. The sample size is 7,500 households (14,000 persons). Sample is based on simple stratified random selection by household dwelling location.


Data on percentage of loss of capacity for work (20, 30, etc., up to 100) and on degree of disability (moderate, severe, profound) are received from the Social Insurance Board


Not used

18.2. Frequency of data collection Frequency with which the source data are collected.

Over ten years

18.3. Data collection Systematic process of gathering data for official statistics.

The household and personal surveys are conducted as a personal interview – the data are entered on a laptop, and from there they will be loaded into a database (CAPI – computer-assisted personal interviewing).

The personal and weekly diaries are filled in by the respondent in hard copy.

Data from the Estonian National Social Insurance Board are received via an FTP-server.

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.

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.
