Income/Expenditure/Household Survey [hh/ies]
The first Household Budget Survey in Latvia took place in 1926-1927, the second in 1936-1937. In the post-war period Family Budget Survey was started in 1952 within the system of the former Central Statistical Board of the USSR. This survey continued also during first independence years of Latvia, after the Soviet Union collapsed. The new Household Budget Survey was introduced in September 1995.
Since 1995, Latvia Household Budget Survey has been conducted annually. Each household included in the sample is surveyed during one month. During the next survey month these households are substituted by others. In the first years of HBS implementation, it was planned to survey 7,992 households per year or 666 households per month.
The Household Budget Survey provides information on qualitative and quantitative indicators of standards of livings in Latvia. The survey gathers data on the structure of households, their revenue and consumer expenditures, employment of the household members, living conditions, possession of consumer durables, access to health care, culture, education, as well as subjective assessments of the households' level of welfare. Data is collected through face-to-face interviews and household expenditure diaries.
Latvia Household Budget Survey was re-designed in 2001 to improve sampling methodology and survey instruments.
Sample survey data [ssd]
The household is the basic unit of the survey. It is defined as a person or group of persons tied by relationship or other personal relations, having common subsistence expenditures and inhabiting the same living unit (house, flat, etc.), maintenance of which is covered by such persons jointly.

Sampling
In rural areas, a two-stage stratified random sampling of households was applied. The administrations of the parishes provided the data. There were 59 parishes, where the number of households was less than 300. 54 of them were added to the neighboring parish. Therefore, 47 primary sampling units (PSU) consist of 2 or 3 parishes. All other 419 parishes form separate PSU. The total number of PSU in rural areas equals 466. These PSU are distributed among 5 strata (geographical regions of Latvia) according to their location.
At the first stage, the PSU were selected within each stratum with probabilities proportional to the number of households of PSU. The total number of selected PSU is 29 and 3 of them consist of 2 parishes each. For all of the 32 parishes selected , a complete list of households was prepared. These lists of households are used to obtain the sample of households at the second stage.
The Population Register was used to obtain the sample of households in urban areas. The 6 administrative districts of the capital Riga and each of the 6 other large towns of Latvia (Daugavpils, Jelgava, Jsrmala, Liepaja, Rezekne, Ventspils) formed 12 separate strata. Simple random sampling of persons (of age 15 years and more) was applied within each stratum. The sample size per strata is proportional to the population size.
All other towns of Latvia were distributed into 10 strata according to their size (more than 7,000 inhabitants or less than or equal to 7,000 inhabitants) and their location (5 geographical regions). Two-stage stratified random sampling was used to obtain the sample. The PSU are the towns of strata and the selection of PSU is conditional to the probabilities proportional to the total number of inhabitants in PSU. At the second stage simple random sampling of persons (of age 15 years and more) was applied within each selected PSU. In urban areas the households of the sampled persons were surveyed.
62%, substitution was not allowed.
Weighting is carried out based both on regional and demographic criteria using the calibration method. Weights of the surveyed households in rural areas were adjusted according to data on the total population and on the distribution of households by their size in rural areas. In the cities, the household weights were adjusted according to the data on the total population and its demographic criteria (sex and age) in the following territories: Riga, each of the 6 major cities and towns. The aggregation of the survey results is made by location according to the structure of the total population.
In order to get unbiased estimates of income and expenditure it is important that the weighted demographic structure of surveyed households corresponds to the results of the population census or demographic statistics. Demographic data by sex, age and urbanisation groups (capital city, Riga, other cities and rural areas) have been used for the calculation of the so-called calibration weights. The calculation was performed by means of the software product CLAN developed at Statistics Sweden.
Survey instrument
Two types of survey forms were developed: the Household Diary and the Household Questionnaire.
The Household Questionnaire is filled in by the interviewer. It consists of two interviews: an introductory interview and a final interview. Whilst the first part contains more general questions in relation to the members of the household, conditions of the living area, employment of the household members, the second part, which is filled in during the final interview, contains questions that might be raised only if a certain degree of trust has been established between the household and the interviewer. These are questions on income of the household members, existence of consumer durables, etc.
The Household Diary is completed by the household itself and it contains data on all money expenditure, goods and services received free of charge or from own production representing all expenditures in relation to the household (in cash and kind). Each household receives two diaries in succession: the first - for the first 15 days of the month, and the second for the period until the end of the month (from 16 to 30 or 31, depending on the month)
In all cases whereby the household sampling list contains a household not found at the given address (false address, change of address, nobody lives at the given address, long-term absence of the addressee, etc.) or a household refuses to participate in the survey, the report on reasons of non-response is completed.

For the purpose of the survey an interview team has been formed and trained, consisting of the following field-work personnel:
- Supervisor performs work with organizations, carries responsibility for the quality of acquired data through the survey, supervises work of interviewers and entry of data;
- Interviewer is responsible for performance of the survey at the given sampling unit;
- Data entry operator (this function, depending on the amount of work, is also performed by the supervisor). The operator performs data entry and examination of indicators.
The selected households have been divided into supervision zones where the supervisor organizes the work in the relevant territory. Each supervisor supervises and inspects a specific number of interviewers. The supervisor has a PC for data entry on magnetic information carriers. This provides the testing devices for the data entry and allows to perform elimination of errors. In cases of errors, the supervisor contacts the interviewer who visits the household in order to inquire about the discovered inaccuracies and probable errors.
In some cases supervisors perform work in two or three adjacent territories of administrative regions. In other cases, the supervisors do their work in addition to their main job, e.g. when the work-load related to supervision is lower due to a small number of interviewers to be supervised.
The supervisor is also the link between the organizers of the survey and the interviewers. His duties are rather wide and they have a significant role in the survey. Supervisors divide the work tasks between interviewers, supply the necessary material, collect and inspect survey documentation, perform survey quality control functions by listening to interviews, performing repeated interviews, ensure that the interviewers act according to the regulations on the survey, control compliance with the individual data confidentiality of the survey, and maintain contact with PSU municipalities. Supervisors simultaneously train the interviewers and assist in their work.
Supervisors also perform activities that upgrade the quality of the survey results, they are responsible for testing of the entry data for correctness, eliminate discovered errors with the help of interviewers and surveyed households, and perform other management tasks related with the survey.
Data processing
Data entry and primary data control is performed at the supervisor's office which is located in the administrative region of the regional state statistical office. For this purpose each supervisor has a PC with a printer. This equipment provides all data entry procedures and print-out of all errors and logical misappropriations discovered during the entry. Operators perform data entry in the supervision areas with a larger number of interviewers (at least 5), whereas the supervisor himself will perform this function in the areas with a smaller number of interviewers. The only exception is Riga, where data entry is organized with the help of professional data entry operators. Data is entered and examined at the location in 15 areas with the DOS program system 'ARIEL-DE'.
Control (discovery) and correction of the mistakes in Households' Questionnaires and Households' Diaries are done with the data entry program. The following operations take place during data entry:
- entry of the data indicators;
- double launching of the control program, which ensures the control of the accuracy of the data entered. The control program looks for "true" mistakes as well as for "possible" mistakes in the questionnaires.
When the data completeness and accuracy control program was developed, a set of events was placed into the memory of the computer (including instructions relating to the coding of data and list of codes). Data that does not correspond to these conditions was regarded as a mistake and classified as a "real" or "true" mistake. Each mistake found or any mismatch of the logical type provokes of a warning on the screen and is simultaneously printed. Thus the supervisor has the possibility to control how the mentioned warnings have been taken into account or ignored by the data entry operator.
The original data entry program creates a separate file for each household containing all the information for this household. This procedure facilitates the detection of errors and the correction procedure. After completion of data entry and correction of discovered mistakes, the data set is copied on diskette. On the respective date of the month, it is sent over electronic cable, using special communication channels of the Post of Latvia to the file server of the Unit of the HBS data processing. Household data files from regions are combined monthly in the theme ASCII- in files with utility program from ARIEL-DE system and SPSS for Windows 6.1.3.
Data appraisal
For estimation of means, totals, ratio and percentages the Horvitz-Thompson estimators are applied. It means that for each household selected into the sample it is necessary to determine probability of its inclusion into the sample.
