3.1. Data description
The EU survey on the use of ICT in households and by individuals is an annual survey conducted since 2002. In Finland, it has been conducted since 2002.
In 2025, the survey collects data on the access to information and communication technologies (ICT), on the use of the internet, e-government and e-commerce, AI, hate speech and doubtful content.
3.1.1. Survey name in national and English languages
National language: Väestön tieto- ja viestintätekniikan käyttö, Befolkningens användning av informations- och kommunkationsteknik
English: EU survey on the use of ICT in households and by individuals
Questionnaire(s) in national language(s) and the translation in English are available in the Annexes.
3.2. Classification system
The following common concepts and definitions apply under the Integrated European Social Statistics (IESS):
- the International Standard Classification of Education (ISCED) 2011 published in the following breakdowns: low (ISCED levels 0-2: no formal education, primary education or lower secondary education), medium (ISCED levels 3-4: upper secondary or post-secondary non-tertiary education) and high (ISCED levels 5-6: tertiary programmes which normally need a successful completion of ISCED 3 or 4, or second-stage tertiary education leading to an advanced research qualification);
- the International Standard Classification for Occupation ISCO-08 at the 2-digit level;
- the Classification of Economic Activities (NACE Rev.2-2008), at section level;
- the Common classification of territorial units for statistics (NUTS 1) – finer granularity of NUTS 2 is provided on optional basis by some Member States;
- the SCL – Geographical code list;
- information about household income is provided at lower level of detail.
Additional classifications used in the national questionnaire: None.
3.3. Coverage - sector
The ICT survey in households and by individuals covers those households having at least one member in the age group 16 to 74 years old. Individuals aged 75 to 89 are covered by some countries on voluntary basis.
Internet access of households refers to the percentage of households that have an internet access, so that anyone in the household could use the internet.
3.3.1. Differences in scope at national level
No deviations
3.4. Statistical concepts and definitions
The survey is mainly collecting data on internet users, individuals who have used the internet in the three months prior to the survey. Some data is collected also about non-users of internet.
This annual survey is used to benchmark ICT-driven developments, both by following developments for core variables over time and by looking in greater depth at other aspects at a specific point in time. While the survey initially concentrated on access and connectivity issues, its scope has subsequently been extended to cover a variety of subjects (for example, the use of internet, e-government, use of eID, e-commerce, e-skills and privacy and protection of personal data) and socio-economic analysis (such as regional diversity, gender specificity, differences in age, education and the employment situation). The scope of the survey with respect to different technologies is also adapted to cover new product groups and means of delivering communication technologies to end-users.
For more details on the methodology applicable in each survey year, please consult the Compiler's Manual for the respective year.
Deviations from standard ICT concepts: None

11.1. Quality assurance
The ICT statistics are official statistics. The Official Statistics of Finland (OSF) is a comprehensive collection of statistics describing the development and state of society. They comprise nearly 300 sets of statistics on 26 different topics. The producers of Official Statistics of Finland have approved a common quality assurance in which they commit to common quality criteria and quality assurance measures. The quality criteria of Official Statistics of Finland are compatible with the European Statistics Code of Practice. The good practices followed in the statistics are presented in Statistics Finland’s Quality Guidelines for Official Statistics handbook.
When compiling statistics, Statistics Finland observes the European Statistics Code of Practice (CoP) and the Quality Assurance Framework (QAF) based on them. The Code of Practice concerns the independence and accountability of statistical authorities and the quality of processes and data to be published. The principles are in line with the Fundamental Principles of Official Statistics approved by the United Nations Statistics Division and are supplementary to them. The quality criteria of Official Statistics of Finland are also compatible with the European Statistics Code of Practice. The principles are also compatible with those of the European Foundation for Quality Management (EFQM).
More information about this is available on Statistics Finland’s quality management pages. Every year Statistics Finland conducts statistical auditing that helps to ensure the quality of statistics.
11.2. Quality management - assessment
The overall quality of the statistical outputs of the survey is good. The statistical outputs are relevant, because main policy and other information needs have been taken into account in planning of the survey. The outputs are also accurate as measurement errors have been minimized with good quality questions and non-response is still quite small. The outputs are timely – the results are published with no major time lag. The data is also delivered to Eurostat according to the schedule. The outputs are comparable over time and geographically. The data is also internally coherent.
12.1. Relevance - User Needs
The data is used nationally by public administration, the media, enterprises, trade and other associations, educational institutes and research institutes. The data is used for information society development, policy design and monitoring, research, teaching and business.
12.2. Relevance - User Satisfaction
Feedback on user satisfaction is got annually from an expert group consisting of users in ministries, enterprises, universities etc.
12.3. Completeness
All variables required are included in the microdata.
12.3.1. Data completeness - rate
100 %
13.1. Accuracy - overall
The accuracy of data collected with a sample survey is affected by measurement errors, non-response and the random variation attributable to the sample. Measurement errors may arise if questions can be understood and interpreted in different ways or if the respondents do not give the requested information. The means by which measurement errors are reduced are the careful planning of the questionnaire forms, testing the form and interviewer training.
The survey’s non-response is classified into unit non-response and item non-response or partial non-response. Unit non-response means that target persons cannot be interviewed at all because they cannot be reached or refuse to be interviewed. Weighting coefficients can be used to correct unit non-response. Item non-response refers to question-specific non-response. In such cases an interview has been conducted but data are missing in certain questions because the interview was interrupted or the interviewee refused to respond.
13.2. Sampling error
The sampling error reflects the fact that only a particular sample was surveyed rather than the entire population. It is estimated by the standard error and can be expressed by the square root of the estimate of the sampling variance. The estimation of the sampling variance should ideally take into account the sampling design (e.g. the stratification).
The estimation method used to calculate the random variation of an estimator is Taylor linearization. The method used to account for the effect of calibration of variation is Deville and Särndal method (1992). As rotating samples and imputation are not used, methods taking into account their effect on precision estimates are needed.
13.2.1. Sampling error - indicators
Precision estimates for the question "Individuals having ordered goods or services for private use over the internet in the last 12 months" (individuals who ticked 'Within the last 3 months' or 'Between 3 months and a year ago' in in the question “When did you last buy or order goods or services for private use over the internet?”):
- Number of respondents (absolute value for ‘Yes’ answers): 2456
- Estimated proportion (in %): 82,04
- Standard error (in percentage points): 0,71
Details of the breakdowns are available in document INFOSOC_HHNSI_A_2025_FI_0000_an_1.xlsx in the Annexes below.
13.3. Non-sampling error
See more details on non-sampling error below.
13.3.1. Coverage error
The frame used in drawing the sample is the Population Information System of Statistics Finland. The frame is updated every month. The sample was drawn right after an update of the frame.
Statistics Finland produces its population information system from the official population system of the Digital and Population Data Services Agency, which is used throughout Finnish society’s information services and management, including public administration, elections, taxation, judicial administration, research, and statistics. The population systems are of high quality. The very small over coverage encountered is due to the fact that small number of individuals in the sample decease after drawing the sample and before the data collection.
13.3.1.1. Over-coverage - rate
0.2 %
13.3.1.2. Common units - proportion
Not requested in the ICT survey.
13.3.2. Measurement error
- Measurement errors: No such measurement errors were encountered.
- Questionnaire design and testing: Questionnaire was designed carefully. Where necessary different versions of question were designed for both data collection modes (CATI and CAWI). The questionnaire was produced in the two national languages of Finland (Finnish and Swedish).
- Interviewer training: Interviewers were trained before start of the interviews. Several interviewers had done interviews of the survey also in previous years
- Proxy interview rates: Proxy interviews are not used.
13.3.3. Non response error
- Information about non-respondents: 47 %
- Information about non-respondents: Persons aged 16-34 and persons with low education are more probable not to answer to the survey than others.
13.3.3.1. Unit non-response - rate
The unit non-response rate is the ratio of the number of in-scope non-respondents (= number of rejected interviews) to the number of eligible elements selected from the sampling frame.
Unit non-response rate for
- Households with at least one member aged 16 to 74 : 47
- Households with at least one member aged 75 to 89, but no member aged 16 to 74: 34
- Individuals (aged 16-74): 47
- Individuals (aged 75-89): 34
13.3.3.1.1. Details of unit non-response rate

Comments, if any:
13.3.3.1.2. Unit non-response – methods, minimization and substitution
- Methods used for dealing with unit non-response: Advance notifications were sent to all persons in the sample prior to data collection. Reminders were used to remind those who had not answered. Advance notifications and reminder are used to motivate respondent to participate. Respondents who had not answered to the calls were called several times.
- Methods used for minimizing unit non-response: None.
- Substitution permitted: No.
- Substitution rate (in %): 0.
13.3.3.2. Item non-response - rate
Items with low response rates (observed rates in %): None
13.3.4. Processing error
No serious processing errors have been encountered in the survey. All phases in the process are checked both by researchers responsible for the survey and experts who have carried out the phase (questionnaire programmer, SAS programmer building the data etc.). Very little editing and imputing is needed; thus, they do not create a big risk for process mistakes. To prevent mistakes more time is used in programming, which allows more time to check the results.

18.1. Source data
The source of the raw data is described with more details in the paragraphs below.
18.1.1. Sampling frame
The Population Information System of Statistics Finland.
The Finnish Population Information System is a computerised national register that contains basic information about Finnish citizens and foreign citizens residing in Finland on a permanent or temporary basis.
The information in the system is used throughout Finnish society’s information services and management, including public administration, elections, taxation, judicial administration, research and statistics. Businesses and other private organisations can also gain access to the information. Basic information related to the identification of people and buildings is registered in the Population Information System.
Personal data recorded in the system includes:
- name
- personal identity code
- address
- citizenship
- native language
- family relations
- date of birth and death (if applicable)
The survey is a stand alone survey. The survey is voluntary. There are no known shortcomings in terms of timeliness.
18.1.2. Sampling design
The sampling used is simple random sampling with one stage and no stratification. Sampling unit is individual. One individual in household is interviewed. There is no longitudinal component in the survey.
18.1.3. Net effective sample size
Restricted from publication
18.2. Frequency of data collection
Annual
18.3. Data collection
1) Methods used to gather data: CAWI and CAPI
2) Short description of the survey method:
A mixed mode data collection, where respondents can choose between filling a web questionnaire (CAWI) or answering in a phone interview (CAPI).
81 % of interviews resulted from CAWI and 19 % from CAPI.
3) Variables completed from an external source: No variables were completed from external sources.
18.4. Data validation
The data of the statistics are validated in many stages during the statistical process. During the processing of the data, the high quality of the data is ensured through various statistical verification programs as well as by comparing the data with previous comparable statistics and other data sources. Checks are programmed into the questionnaire that prevent illogical answer combinations and unanswered questions. Following the data collection, the data are checked. Incomplete responses and other invalid observations are removed.
18.5. Data compilation
No imputation is done.
Data for some socio-demographic background variables is taken from registers. This is done already in formation of the sample.
The data are weighted to correspond to the population and households in the entire country, accounting for non-response. Individual weighting, the numbers of both respondents and the population are tabulated according to sex, age, level of education, native language, region and the statistical grouping of municipalities.
18.5.1. Imputation - rate
For the target indicator "Individuals having ordered goods or services for private use over the internet in the last 12 months" (individuals who ticked 'Within the last 3 months' or 'Between 3 months and a year ago' in the question “When did you last buy or order goods or services for private use over the internet?”:
- Imputation rate (% of observations): 0
- Imputation rate (share of estimate): 0
18.5.2. Use of imputation methods
Methods used to impute item non-response: None
18.5.3. Grossing-up procedures
Grossing up procedures have been applied to: Individuals and Households
Description of the weighting procedures:
Individuals: Design weights were calculated by dividing population size by the number of respondents. Calibration weights were calculated using design weights as starting weights in calibration. Following register variables were used in calibration: level of education, language, region (NUTS 3) and a combination of age group and gender.
Households: Inclusion probabilities were calculated as follows: prob = the number of people aged 16 and over in the household / (population size / number of respondents)
Design weights were inverse of the inclusion probabilities. Calibration weights were calculated using design weights as starting weights in calibration. Following register variables were used in calibration: the size of the household and region (NUTS3).
