| 1 | Data description | Survey objects in the Urban Audit are the private households. The variables definitions used in the survey are in conformity with standard EU-SILC concepts and definitions and Urban Audit requirements for the indicators (variables) provided. Private Household is defined as a person living alone or a group of people who live together in the same private dwelling and share expenditures, including the joint provision of the essentials of living. The following persons must, if they share household expenses, be regarded as household members: • usually resident, whether or not related to other members; • boarders, lodgers, tenants, visitors, live-in domestic servants, au-pairs who have no alternative private address; • temporarily absent (<6 months) (eg. for work, holiday, education) and no alternative private address; • absent for longer (eg. for work, education) but with ties to household members (partner or child), in regular contact and no alternative private address; • temporarily absent (<6 months) in an institution (eg. for medical treatment), but with ties to household members and no alternative private address. Household with children aged under 18 is a private household (one family households or two or more families households) with one or more adults (over 18 years old) and at least one child (under 18 years old). These four variables are fixed as key variable for the Urban Audit. Disposable household income (net of any taxes and social contributions paid) includes: • all income from work (employee wages and self-employment earnings); • private income from investment and property; • transfers between households; • all social transfers received in cash including old-age pensions; Disposable household income does not include: • income from private pension plans; • in kind social transfers; • imputed rent; • income in kind, with exception of company car; • own consumption. |
| 2 | Classification used | Unified Classification of Administrative-Territorial and Territorial Units (UCATTU) |
| 3 | Coverage | The sample contains 4 independent sub-samples and follows stratified two-stage cluster sampling design. The sample is stratified by administrative-territorial districts in the country (NUTS3) and the household’s location. As a result 56 strata are formed (28 of urban and 28 of rural population). Municipalities and settlements are ranged according to the number of their population within each stratum. Weighting factors were calculated as required to take into account the units’ probability of selection, non-response and to adjust the sample to external data relating to the distribution of households and persons in the target population, such as sex and age, residence or region (NUTS II).All private households in the country are covered (excluding institutional and collective households). Data estimates prepared for Urban Audit are based on the original SILC data, weighted by the personal cross-sectional weight and aggregated for the corresponding Larger Urban Zone (LUZ) and city. |
