Quality report
Data description (SIMS 3.1)
The household budget survey describes changes in households' consumption expenditure and differences in consumption. The survey also studies households’ housing conditions, means of transport and income at disposal, for example. The survey is a sample survey, which is carried out and published irregularly.
Sector coverage (SIMS 3.3)
The statistics on households' consumption cover the consumption expenditure of private households permanently resident in Finland.
The representative population sample of the statistics on households' consumption describe the economic well-being of households and persons as a whole more extensively than any other statistical data. In addition to the demographic and regional data on households, the statistics also contain data on households':
– consumption expenditure
– disposable income
– interests on housing loans and other loans – housing conditions
Statistical unit (SIMS 3.5)
The basic unit of the statistics on households' consumption, on which data are produced, is a household. It consists of persons who live together and who have, in whole or in part, a shared food economy or otherwise use their income together. Consumption data are collected and analysed mainly by household, even though data by household member are also collected.
Statistical population (SIMS 3.6)
The population of the statistics on households' consumption consists of households permanently resident in Finland and their members. Excluded from the statistics are Finnish citizens resident abroad and the institutional population, which includes long-term residents of hospitals, old people's homes, care institutions, prisons, etc.
Reference area (SIMS 3.7)
The statistics on households' consumption cover the consumption expenditure of the household population permanently resident in Finland.
The data of the statistics are published on the level of the whole country and by major region (NUTS2).
Time coverage (SIMS 3.8)
The statistics on households' consumption, or the Household Budget Survey, are one of the oldest sample surveys in Finland, their history reaches back to the years 1908 to 1909. Household Budget Surveys covering all households in Finland have been conducted approximately every five years since 1966. Starting from 1966, data are available in electronic format.
Two time series have been produced based on the data, of which the older one contains comparable data for the years 1966, 1971, 1976, 1981, 1985 and 1990. The newer time series contains data for the years 1985, 1990, 1995, 1998, 2001, 2006, 2012 and 2016.
The Household Budget Survey 2022 starts a new time series with the new COICOP2018 classification.
Unit of measure (SIMS 4)
The published data of the statistics on households' consumption use consumption expenditure in euros, on average, per household or per consumption unit as the unit of measurement.
Reference period (SIMS 5)
The reference period of the statistics on households’ consumption is the calendar year. In the data collection, the reference periods are two weeks, one month, three months or one year. The consumption data inquired for a period of under 12 months are scaled to the annual level in the final data. When planning the data collection, attention is paid, for example, to the frequency of goods and services acquisition and the price of them. These influence how the data are collected and what kind of reference period is used in the question.
Concepts and definitions (SIMS 3.4)
Consumption expenditure per household
The average number of persons in a household has a fundamental effect on the expenditure averages per household of different population groups. The expenditure of families with children per household is larger than in small households (e.g. one-person households and elderly households).
Consumption unit
Income and consumption expenditure calculated per consumption unit can be used to compare households of different sizes and structures with each other. There are several different ways of calculating consumption units. From 2002, the income distribution statistics and the Household Budget Survey have used the OECD's adjusted consumption unit scale recommended by Eurostat, the Statistical Office of the European Communities, where - the first adult of the household receives the weight 1 - other over 13-year-olds receive the weight 0.5 - children receive the weight 0.3 (0 to 13-year-olds). The selected consumption unit scale has a significant effect on income levels and on placement of different population groups in the income distribution.
Disposable income
In the income distribution statistics and in the Household Budget Survey, households' disposable income included all salaries and wages, entrepreneurial income and property income (including imputed rent from owner-occupied dwellings and taxable sales profits from property), benefits in kind and current transfers received, from which sum, current transfers paid were deducted. The formation of disposable income can be described as follows: + Wages and salaries + Entrepreneurial income + Property income (incl. imputed rent from owner-occupied dwellings and sales profits) ----------------------------------------------- = Factor income + Current transfers received (incl. imputed rent from a rental dwelling from another household) --------------------------------------------- = Gross income – Current transfers paid -------------------------------------------- = Disposable income Before the statistical reference year 2011, the income distribution statistics primarily utilised the concept of disposable income. The imputed rent of owner-occupiers was regarded as factor income (property income) and imputed rent for a dwelling rented from another household as current transfers received in the income distribution statistics. Imputed rent is still formed in the income distribution statistics but from the statistical reference year 2011, it is treated as a separate income item (see "Imputed rent"). Similarly, taxable realised capital gains or sales profits are treated as a memorandum item according to international recommendations. When social current transfers in kind are added to income, adjusted disposable income is obtained. This concept is not formed in the income distribution statistics. Wages and salaries include income paid for households as pay - either in money or benefit in kind. Income from incentive stock options is included in the income concept in benefits in kind and thus in wages and salaries. Entrepreneurial income includes income from agriculture and forestry, business activity and business group and copyright fees. Entrepreneurial income in agriculture also contains various subsidies and compensations such as agricultural subsidies, European Union agricultural aid and compensation for harvest losses. Property income is rental, interest and dividend income received by households, imputed net rent from an owner-occupied dwelling, taxable capital gain and pensions based on private insurance and other income. Current transfers received comprise earnings-related pensions and national pensions and other social security benefits, social assistance and other current transfers received. Current transfers paid comprise direct taxes and social security contributions. In addition, current transfers paid comprise compulsory pension and unemployment insurance premiums and in the income distribution statistics also child maintenance support paid. The key income distribution statistics concept, disposable income, is arrived at when current transfers paid are deducted from gross income. The concept of disposable income in the Household Budget Survey is based on register data, and does not, differing from the income distribution statistics, include wages and salaries subject withholding tax and tax-free interest income and current transfers between several households (e.g. child maintenance support).
Durability classification
The consumption expenditure groups of the Classification of Individual Consumption According to Purpose (COICOP) are divided in accordance with the principles of the system of national accounts into services (S), nondurable goods (ND), durable goods (D) and semi-durable goods (SD). The difference between nondurable goods and durable goods is based on whether the goods can be used only once, or repeatedly or continuously during a period of over one year. Durable goods, such as cars, fridges, washing machines and televisions, also have a relatively high purchase price. Semi-durable goods differ from durable goods in that their expected service life, although over one year, is often considerably shorter and their purchase price lower. Statistics Finland's COICOP handbook can be browsed on the Internet at www.tilastokeskus.fi/tk/tt/luokitukset/popup/coicop.pdf (Handbooks / Statistics Finland, 41).
Final consumption expenditure
Final consumption expenditure of households includes all goods and services acquired by the household from Finland and abroad for its private consumption during the survey period, including own and received gardening and collected products and imputed housing expenditure. Repayment of housing and consumption loans is not included in consumption expenditure. Consumption expenditure does not either contain direct taxes, investments (e.g., purchase of a dwelling), expenditure of business activities. The consumption concept does not include benefits gained from households' use of public welfare services (e.g., health care and education). Households' final consumption expenditure is formed as follows: + purchases of consumption goods and services + own products (agricultural, gardening and collected products) + imputed dwelling income from an owner-occupied dwelling and a dwelling provided as a benefit in kind + current transfers comparable to consumption (e.g., church tax and labour union membership fees and interest on consumption loans) = total consumption expenditure Starting from the statistical reference year 2022, goods and services received are not included in final consumption expenditure.
Household
A household is formed of all those persons who live together and have meals together or otherwise use their income together. The concept of household is only used in interview surveys. Excluded from the household population are those living permanently abroad and the institutional population (such as long-term residents of old-age homes, care institutions, prisons or hospitals). The corresponding register-based information is household-dwelling unit. A household-dwelling unit is formed of persons living permanently in the same dwelling or address. More than one household may belong to the same household-dwelling unit. The concept of household-dwelling unit is used in register-based statistics in place of the household concept.
Household's reference person
The person with the highest personal income is chosen as the household's reference person. The reference person is defined according to interview data. Income is mainly the criterion determining the reference person, but in some cases (e.g., entrepreneur households) the activity of the whole household is taken into account. Starting from the statistical reference year 2022, the reference person has been defined based on register data. The reference person is the household member with the highest income. A considerable part of household-specific classifying data is formed on the basis of the reference person's data.
Housing consumption
In the Household Budget Survey housing consumption is calculated by the so-called gross rent principle. There an imputed rent is determined for households living in their own dwelling or in a dwelling provided as a benefit in kind based on the market rent of a comparable rented dwelling, and the actual rent paid for those living in a rented dwelling. In determining the gross rent of one's own dwelling use has been made of data in Statistics Finland's statistics on rents of dwellings and household register or interview data concerning the number of rooms in the dwelling, year of construction, heating mode and location. In addition to gross rent, housing expenditure includes water charges and some other payments such as chimney-sweeping and refuse collection, maintenance repairs made by the tenant and heating costs not included in the rent. Expenditure of free-time residences is also included in housing expenditure.
Own products
In the Household Budget Survey household consumption includes natural products produced and received by the household, such as agricultural, gardening and collected products (berries, mushrooms, fish, etc.). In the questionnaire households are asked about the used amounts of own products, after which they are priced at consumer prices.
Socio-economic group
Starting from the statistical year 2022, the socio-economic group is formed for household members on the basis of the person's activity on the time of the interview. For determining the socio-economic group, persons are first divided into economically active and inactive. Economically active are further divided into self-employed and wage and salary earners on the basis of information reported in the interview. Wage and salary earners are divided into employees and upper and lower level office workers. Economically inactive are grouped into students, pensioners, unemployed and others. Unemployed are persons who have been unemployed for at least six months during the year. The socio-economic group of the household is determined by the household's reference person. The classification is based on the Statistics Finland's classification standard of socio-economic groups from 1989. There account is taken of the person's occupation, status in occupation, nature of work and stage in life (Classification of Socio-economic Group 1989. Helsinki. Statistics Finland, Handbooks, 17).
Institutional mandate (SIMS 6)
The compilation of statistics is guided by the Statistics Act. The Statistics Act contains provisions on collection of data, processing of data and the obligation to provide data. Besides the Statistics Act, the General Data Protection Regulation, the Data Protection Act and the Act on the Openness of Government Activities are applied to processing of data when producing statistics.
Statistics Finland compiles statistics in line with the EU’s regulations applicable to statistics, which steer the statistical agencies of all EU Member States.

Data sharing (SIMS 6.2)
The data of the statistics on households' consumption are submitted to the Consumer Price Index, the international price comparison and national accounts. In addition, the data of the statistics are submitted to Eurostat and Eurostat publishes the data on its web pages.
Eurostat, the Statistical Office of the European Union, is responsible for compiling statistics on the HBS and for the release of its statistical data for research use. Research use requires an application for licence to use statistical data.
Frequency of data collection (SIMS 18.2)
The data collection for the statistics on households' consumption is conducted roughly every five years. The latest is from 2022.
Data collection (SIMS 18.3)
The data for the statistics on households' consumption 2022 were collected with telephone interviews and self-filled web questionnaires. In addition, data was obtained from purchase receipts collected by the household and from purchase entries made in the consumption diary. A Household Budget Survey mobile application was also offered to respondents for scanning purchase receipts and recording consumption data. Data were also retrieved from administrative registers.
In the contact interview, the structure of the household according to register data is checked and data are collected on the household members (occupations, activity on the labour market, etc.) and the respondent is directed either to continue the interview by telephone or to independently fill in the web questionnaire with the same content. In the interview and web questionnaire, data are inquired on households' expenditure, such as housing, insurance and large purchases, and owning durable consumer goods.
Statistics Finland’s own interviewers carry out the interviews. After the interviews, the households collected receipts concerning all their expenses during two weeks or recorded the purchases either in the Household Budget Survey mobile application or in the paper consumption diary. The sample households of the survey were randomly divided into 26 receipt collection periods of 14 days throughout the survey year. Thus, as comprehensive and reliable data as possible are obtained on the consumption in different seasons. If the respondent had selected the mobile application for the receipt collection period, the receipts were photographed with it or purchases without receipts were recorded in the application diary. The receipt photographs were transmitted from the application to Statistics Finland where they were read with OCR software and classified with the help of a classification algorithm. The physical receipts were returned either to the statistical interviewer with whom an agreement had been made about the collection of receipts or directly to Statistics Finland. The receipts were scanned and converted to electronic format at Statistics Finland. Administrative registers were utilised in collecting background data. For example, data on the income and education of household members and on the use of public services were obtained from them.
User needs (SIMS 12.1)
National accounts produce macro level data on the consumption expenditure of the household sector at the level of the whole national economy annually. The data of the Household Budget Survey are used in the level revisions of household sector consumption. The main source for the structure of the commodity basket of the Consumer Price Index is national accounts data on private consumption, which are supplemented with more detailed data from the Household Budget Survey.
The Household Budget Survey describes households' resources of economic well-being, which is why it is close in terms of content to the income distribution and wealth surveys. Households' consumption also includes activities which link the Household Budget Survey to time use, cultural and leisure surveys, as well as surveys and statistics describing the environment and the mass media.
Universities and research institutions use the data of the Household Budget Survey when studying, for example, the distribution of well-being by population group or region, poverty and social exclusion or social problems. The data are also used in the so-called lifestyle survey and econometric surveys. Consumption data are also linked to the microsimulation model (SISU). In addition, Statistics Finland makes data analyses and printouts as information service, based on the needs of the users.
User satisfaction (SIMS 12.2)
Users' views and opinions are not collected regularly. Based on the number of parties ordering chargeable data, the content is perceived to be relevant. In connection with changes concerning the statistics, an expert group has been heard.
Quality assurance (SIMS 11.1)
Quality management requires comprehensive guidance of activities. The European Statistics Code of Practice forms the basis for the common quality system of the European Statistical System.
The Code of Practice is based on 16 principles that concern statistical authorities' independence, accountability and the quality of the processes and data to be published.
The principles are in line with the Fundamental Principles of Official Statistics approved by the United Nations Statistics Commission and are supplementary to them. The quality criteria of Official Statistics of Finland are compatible with the European Statistics Code of Practice.
Further information: European Statistics Code of Practice | Statistics Finland and Recommendations of the Advisory Board of Official Statistics of Finland | Statistics Finland
Quality assessment (SIMS 11.2)
Official Statistics of Finland (OSF) are 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.
Data revision - policy (SIMS 17.1)
Revisions – i.e. improvements in the accuracy of statistical data already published – are a normal feature of statistical production and result in improved quality of statistics. The principle is that statistical data are based on the best available data and information concerning the statistical phenomenon. On the other hand, the revisions are communicated as transparently as possible in advance. Advance communication ensures that the users can prepare for the data revisions.
The reason why data in statistical releases become revised is often caused by the data becoming supplemented. Then the new, revised statistical figure is based on a wider information basis and describes the phenomenon more accurately than before.
Revisions of statistical data may also be caused by the calculation method used, such as annual benchmarking or updating of weight structures. Changes of base years and used classifications may also cause revisions to data.
Timeliness (SIMS 14.1)
The statistics on households' consumption are produced at intervals of five years, on average. The results of the statistics are released as preliminary data approximately 12 months after the statistical reference year and as final data at a lag of approximately 15 months.
Time series corrections caused by methodological changes etc. are made when necessary.
Punctuality (SIMS 14.2)
As a rule, there has been no delay between the release calendar and the actual release date in the statistics on households' consumption. In individual cases, the release has had to be postponed.
Comparability - over time (SIMS 15.2)
Two national time series have been produced based on the data of the statistics on households’ consumption, i.e. the data of the Household Budget Survey, of which the older one contains comparable data for the years 1966, 1971, 1976, 1981, 1985 and 1990. The newer time series contains comparable data for the years 1985, 1990, 1995, 1998, 2001, 2006, 2012 and 2016.
The Household Budget Survey 2022 starts a new time series with the new COICOP2018 classification.
Coherence – cross domain (SIMS 15.3)
When comparing the data of the statistics on households' consumption with the consumption expenditure of the household sector of the national accounts, differences in defining the sector, data collection and definitions, as well as in the compilation methods of the statistics, should be taken into account. In different statistical reference years, there are some differences in total expenditure between the national accounts and the Household Budget Survey. In 2022, the consumption expenditure estimated based on the Household Budget Survey was good 85 per cent of the corresponding sum of national accounts. Due to differences in calculation methods, the deviation cannot be regarded as very significant. For example, the sample size, participation in the surveys and modes of data collection have varied from one Household Budget Survey to another. In national accounts, the Household Budget Survey is used for level revision of private consumption expenditure.
Coherence - internal (SIMS 15.4)
The data of the statistics are internally coherent. There are no differences in definitions or examination periods within the same set of statistics.
Release calendar (SIMS 8.1)
Statistics Finland publishes new statistical data at 8 am on weekdays in its web service. The release times of statistics are given in advance in the release calendar available in the web service. The data become public after they have been updated in the web service.

Confidentiality - data treatment (SIMS 7.2)
Statistics Finland's general guidelines are applied in the publication of tabulated statistical data of the statistics on households' consumption.
An individual household cannot under any circumstances be identified from the published data.
Release of data for research use is done centrally by Statistics Finland's research services. The survey data of the Household Budget Survey are mainly household-specific and households are identified with consecutive numbers. Some of the classification data of the household are person-based. The data do not contain identification data. In addition, before granting a licence to use the data and releasing the data for research use, the data protection of the data is assessed in accordance with the normal practice of the research services and the data are made less detailed if necessary.
Unit-level data are released to Eurostat. The released data do not contain identification data.
