Income and living conditions of the population of Lithuania (edition 2020)
The Survey on Income and Living Conditions (EU‑SILC) was launched under Regulation (EC) No 1177/2003 of the European Parliament and of the Council of 16 June 2003 concerning Community statistics on income and living conditions (EU‑SILC) in all Member States of the European Union. The aim of the survey is the production of statistics on income of the population, level and composition of poverty and social exclusion, persistent poverty, which would be comparable at the EU level. In Lithuania, the Survey on Income and Living Conditions has been carried out since 2005.
The target population of the EU‑SILC are private households. Persons living in institutional households (e.g. care or imprisonment institutions etc.) are excluded from the current survey. Households are selected from the Residents’ Register using a random sampling method. Such a method is expected to ensure equal possibilities for the representatives of all social strata to be selected for the survey.
The survey collects information on household income, housing and living conditions, employment (activity status), health status, access to health care, financial and housing problems, possibility to meet certain needs.
Statistical data are collected through face-to-face interviews of all respondents aged 16 and over. Additional information is obtained from the Residents’ Register, the State Tax Inspectorate, the State Social Insurance Fund Board, and the Ministry of Social Security and Labour.
The target population are all private households of Lithuania. For the 2019 survey, 6,966 households were selected, of which 5,131 participated in the survey.
A stratified sampling design was used. The entire Lithuanian territory was divided into 25 non‑overlapping groups – strata. The population of the five largest cities of Lithuania, towns of each county and rural areas of each county was divided into separate strata. The size of the sample of households in every stratum is proportional to the number of residents aged 16 and older in them. From every stratum, a household sample with probabilities proportional to the size of the household was selected.
The sample for any year consists of four replications. Any particular replication remains in the survey for four years; each year, one of the four replications from the previous year is dropped and a new one is added.
