Tables 9-1 to 9-6. Composition of samples of reporting households and the structure of the money income and expenditure of households
Listed in the tables are data from the sample survey of household budgets. The household - i.e. the number of persons living together and on common budget - constitutes both the reporting and sample unit. As a rule, the core of the households is a family but it can also be an individual. Households (respondents) included in household budget statistics are now sampled by the method of purposive quota sampling.
There are two types of samples used:
1. Basic reporting sample, which ensured representative results for social groups in the Czech Republic. The frequency of individual groups of households according to sampling characteristics is determined with reference to results from the sample survey on the money income of the population (microcensus). The following sampling characteristics were used to select the households:
a) Social group of households, which is determined according to which social group the head of household belongs to, irrespective of whether or not another economically active member of the household belongs to the same or different social group. Where the household is constituted by a two-parent family (husband, wife, other members), the husband is always the head of household, whereas an economically active parent is the head of household in lone-parent families. An economically inactive parent can become the head of household provided that the children are also economically inactive. In other cases an economically active child is the head of household. In non-family households, the head of household is always the person with the highest income. Where a household embraces two or more families, the position of persons in the head of individual families is taken account of: preference is always given to an economically active person and, with the same degree of economic activity, two-parent family is preferred to lone-parent one. If these criteria cannot be applied, the person with the highest income is set as the head of household.
Measured were the social groups of:
- employees: persons having a contract of employment, who do manual work in the area of production, transport, services, etc. (manual workers) or intellectual work at all levels such as managerial, conceptual and scientific, operational, technical, services (other employees);
- farmers: persons who are engaged in agricultural production and are either members of and work for an agricultural cooperative or are engaged in agricultural production in enterprises of any kind or are self-employed in agriculture production;
- self-employed persons: persons who have no contract of employment and are in business outside agriculture, work freelance or work for professional fees;
- pensioners: pension recipients who do not work at all or whose economic activity is restricted (their annual income from gainful activity is not allowed to exceed CZK 12 000; this restriction applies to other members of the household, too).
b) Net money income per person: it characterizes the income level of households not only for the purpose of sampling but also for that of classifying these households by income level when data are processed; the net income does not include income tax, health and social insurance reimbursements, loans, credits received and savings withdrawn;
c) Number of unprovided-for children in households of economically active persons or the number and sex of members in households of economically inactive pensioners.
2. Supplementary sample which comprised families with children, living just at subsistence level. An appropriate number of these families were represented in the basic sample, too. For separate processing, however, they would be too low in number.
Methodology and definitions of key indicators
Number of equivalencies refers to the composition of household derived from weights of consumption of individual members in the household. The weights are defined by the OECD scale as follows: first adult in the household = 1.0, every other adult (over 13 of age) = 0.7, every child (aged 13 or less) = 0.5.
Money income, total is gross money income. It includes income tax and social and health insurance contributions and excludes loans and deposits withdrawn.
For households of the self-employed, the money income includes amounts transferred by these persons from profits of their businesses to satisfy the needs of their households and members of the households. It is comparable to the income of the households of other social groups at the level of the so-called net income only (excluding income tax and contributions to health and social insurance schemes). For most of the self-employed, tax burden of their households is not fully covered, because contributions to health and social insurance schemes are part of their bookkeeping and are not reported in household budgets statistics. Income tax is included in household budgets statistics only if it is paid from funds of the household.
Income from work refers to incomes from work activities carried out in the framework of employment, service and membership relationships or incomes from business or any other independent gainful activities; such incomes are referred to as incomes from main activity, if the activity is the main source of the worker’s income.
To ensure international comparability of the statistical indicators, the items of money expenditure relating to 1999 and subsequent years were re-arranged to comply with the national version (CZ-COICOP) of the international Classification of Individual Consumption by Purpose, COICOP (see the statistical classifications in force listed in the introduction of this book), which is obligatory for all statistical surveys. According to this classification, the individual (final) consumption includes neither expenditure on the purchase, building and reconstruction of houses and dwellings nor expenditure on kitchen gardens and domestic animals (not pets), which is why these were placed under a separate item not included in final consumption
The application of this classification altered the contents of some expenditure items and, therefore, the results are not fully comparable with figures released before 1999. The groups of expenditure items regarding 1995 and to some extent 1995 were converted to comply with the above-mentioned classification so that trends in the basic results of household budgets statistics can be compared over a prolonged period of time.
Money expenditure, total includes neither deposits nor repayments of loans.
The individual expenditure items are the following:
- housing, water, electricity, gas and other fuels: rental, other services related to the dwelling, central heating and hot water, electricity, gas and other fuels, and services for maintenance and repair of the dwelling;
- furnishings, household equipment and routine maintenance of the house: furniture, fixtures, household textile, refrigerators, washing machines and other appliances, tools and equipment for house and garden, repairs of all machines and equipment, chemist's goods, services for households (laundering, dry-cleaning, cleaning, etc.),
- recreation and culture: equipment and supplies for leisure (TV sets, videos, radio receivers, tape recorders, also in combination, personal computers, cameras, typewriters, musical instruments, stationery, articles for painting, LPs, CDs, cassettes and other small goods of cultural nature, toys, equipment for sports), repairs of all equipment, devices and instruments, books (incl. textbooks), newspapers and periodicals, leisure time services (admission and other fees relating to cultural, entertainment and sports events and activities, supplies and equipment for pets and for growing flowers and other ornamental plants, radio and TV licence fees, service charges for lotteries and gambling, package holidays);
- miscellaneous goods and services: personal care and services (beauty products, articles and appliances for personal hygiene, watches, jewels, artificial jewellery, travelling articles, repairs of these articles, appliances and supplies, services of hairdressing salons, beauty parlours and other personal services), social care expenditure, all types of insurance and services n.e.c. (financial, administrative, advisory, etc.).
The coverage of the other items is evident from their names.
Table 9-1 lists figures on households as a total for the basic reporting sample. The figures refer to 2000-2003. They are compared with 1995 and converted to be governed by the methodology in use since 1999.
Tables 9-2 and 9-3 show figures for the basic reporting sample, broken down by social group, which are supplemented with estimates for households in total (figures for the samples concerned were re-weighted by social structure of households established by the Microcensus 2002).
Tables 9-4 to 9-5 show statistics on the supplementary and basic reporting samples of households whose net incomes did not exceed 1.4 multiple of the subsistence level calculated from rates in force for a given household (see the table in the introduction to Chapter 24. Social Security, showing subsistence level amounts).
The term two-parent nuclear family refers to a family consisting of a married couple and unprovided-for child/children, in which neither other relatives nor economically active child/children live.
The term lone-parent nuclear family refers to a family consisting of a single parent and unprovided-for child/children, in which neither other relatives nor economically active child/children live.
Table 9-6 presents figures related to the basic sample of household budgets statistics, broken down by net money income per household member per year. Each social group in low income brackets includes 20% of households with the lowest net money income per 1 household member. The net money income of each of the households classified to this group did not exceed the upper net income limit shown in the table. The group of high-income households also included 20% of households with the highest net money income per 1 household member in each social group, the net money income of these households being above the lower limit shown in the table.
Table 9-7. Households on common budget: by social group; 2002 and
Table 9-8. Persons in households with income under poverty line: 2002
The results were obtained by the sample survey “Microcensus 2002” and the presented data were derived for 7 973 households on common budget from the whole of the Czech Republic. The survey measured incomes of persons and households for the whole year 2002 and demographic data as at the end of 2002. The data on economic activity, type of employment and branch of economic activity were reported according to the prevailing status or, in case of equality, as at the end of the year 2002. They were grossed up to cover the whole population of the Czech Republic.
Household on common budget is based on the declaration on common living and budget of the persons in a dwelling.
Gross money income includes income tax and health and social security contributions and excludes savings withdrawn and loans. Income from self-employment refers to gross economic result (profit/loss) before tax.
Net money income of household is the income after income tax and social and health security contributions.
Subsistence level of household (see Chapter 24. Social Security) was calculated for each household included in the processing with regard to the number of household members and the age of unprovided-for children.
Equivalency is the quantity, which takes into account the demographic composition and size of the household. The number of equivalencies per each household was calculated by re-weighting the household members using weights according to the methodology applied in the EU, as follows:
- first adult member of the household was assigned the weight of 1.0
- child aged under 14 was assigned the weight of 0.3
- all the other members of the household aged over 13 were assigned the weight of 0.5.
Equivalised income is the income per equivalency and was derived as the ratio of the net money income of the household and the number of its equivalencies.
Poverty line – was set in compliance with the EU methodology of the EU which uses 60% of the median of equivalised income for all households as the relative poverty line (low income threshold).
Households of working persons - households with at least one economically active member.
Households of non-working persons - households composed of retired, unemployed and other inactive persons.
Education level of household is determined according to the highest educational achievement of the head of household or the partner thereof. The households were classified to the individual groups of education as follows:
- low level: the highest educational attainment of both partners is basic (including basic education not completed),
- intermediate level: the highest educational attainment of either partner is secondary,
- high level: the highest educational attainment of either partner is university.
Type of household - two-parent families only include two-parent nuclear families composed of both parents and children.
Dependent child - included are all children under 16 and children aged 16 to 24 provided that they are not economically active.
The applied EU methodology ensures that the Table 9-8 data are fully comparable on an international scale.
Table 9-9. Per capita consumption of the most important kinds of food
The consumption is calculated by balancing, from figures on industrial production, self-supplies, initial and final stocks, imports and exports. These figures are taken from statistical questionnaires monitored by the CZSO. They are also obtained from individual food unions, some external trade organizations, the State Veterinary Administration, and other institutions. The table shows average annual consumption per capita (with reference to mid-year population).
The individual figures are comparable with previous years and linked to the indicators listed in Chapter 1. Key Indicators of the National Economy.
Table 9-10. Per capita consumption of selected basic kinds of manufactured goods
The consumption is derived by a balancing, from figures on production, stocks, imports and exports. These figures are taken from statistical questionnaires monitored by the CZSO. They are also obtained from individual manufacturers and organizations engaged in external trade. Gas and power consumption is derived from information provided by the gas utilities concerned.
The individual figures are comparable over long-time series.
Table 9-11. Consumer durables in households
The figures on consumer durables in households are derived from figures on production, stocks, imports and exports, by cumulating annual increments and taking account of the service life (determined by the Research Institute of Trade) or wear and tear of the durables. The figures on cars and motorcycles are calculated from information provided by the Ministry of the Interior of the Czech Republic and on telephones by TELECOM Co. and mobile network operators.
The individual figures are comparable over long-time series.
