3.1. Data description:Survey on income and living conditions - EU SILC annually provides comparable data on income, poverty, social exclusion and living conditions.
3.2. Classification system:ISCED 1997, ISCED 2011, NACE Rev. 2, ISCO 08
3.3. Sector coverage:Not relevant.
3.4. Statistical concepts and
At-risk-of-poverty rate means a share of persons (in total population) whose equivalised disposable income is below the relative poverty line. These persons are not necessarily poor, but they are at higher risk to be poor. At-risk-of-poverty threshold (relative poverty line) represents 60% of the median of national equivalised disposable income of all households and it is expressed in euro. Quintile share ratio (S80/S20) compares the total equivalised disposable income of the upper income quintile (20% of the population with the highest equivalised income) with those from the lower income quintile (20% of the population with the lowest equivalised income). It is an indicator of income inequality which measures the relationship between the first and fifth income distribution quintals. Gini coefficient in this survey represents the measure of inequality in the distribution of equivalised disposable income. The value of this coefficient goes within the interval from 0 to 100, where 0 represents perfect equality, i.e. each person in society has equal income. The closer to 100 the value is, the income inequality is higher.

                                                                                  13. Accuracy and reliability                                                              Top
13.1. Overall accuracy:Survey on Income and Living Conditions is sample-based survey, and accordingly the results obtained from the sample are subject to the usual types of errors related to sampling techniques and interviews, such as: sampling errors, non-sampling errors, measurement errors, processing errors and non-response.
13.2. Sampling error:EU-SILC is a complex survey involving different sampling design in different countries. In order to harmonize and make sampling errors comparable among countries, Eurostat has chosen to apply the linearization technique coupled with the ultimate cluster approach for variance estimation. The ultimate cluster approach is a simplification consisted in calculating the variance taking into account only variation among Primary Sampling Unit (PSU) totals. According to the characteristics and availability of data for different countries, different variables for determining the strata and clusters were used. For sample design, MONSTAT uses a two-stage stratified sample DB050 (primary strata) to determine the stratum and DB060 (PSU) to determine the cluster.
13.3. Non-sampling error:Non-sampling errors are basically of 4 types: 1) Coverage errors - errors due to divergences existing between the target population and the sampling frame. 2) Measurement errors - errors that occur at the time of data collection. There are a number of sources for these errors such as the information system, the interviewer and the mode of collection. 3) Processing errors - errors in post-data-collection processes such as data entry, keying, editing and weighting. 4) Non-response errors - errors due to an unsuccessful attempt to obtain the desired information from an eligible unit. Two main types of non-response errors are considered: - Unit non-response - refers to absence of information of the whole units (households and/or persons) selected into the sample and - Item non-response - refers to the situation where a sample unit has been successfully enumerated, but not all required information has been obtained.

14.1. Timeliness:The preliminary data are published 19 months after the completed reference period. The final data are published 26 months after the completed reference period. Timeliness of final data: T+31 months after the completed reference period.
14.2. Punctuality:The punctuality indicator represents the time difference between the actual publication of the data and the planned publication of the data. Deadlines of dissemination of the EU-SILC data at the website are defined in the Statistical Release Calendar and these deadlines are respected. Indicator TP3 (punctuality) is 0, i.e. no difference between the actual publication of the data and the planned publication of the data, that means that the Releases are published according to the deadlines which are defined in the Statistical Release Calendar.

18.1. Source data:Survey on income and living conditions is a sample-based survey. The household selection framework is the Census of population, households and dwellings in 2011. The sample of households is a two-stage stratified sample by regions (north, center, south and Podgorica) and type of settlement (urban, others), where the units of the first stage are the enumeration areas and household as units of the second stage. The annual sample is about 5 519 households. Household substitutions are not allowed. The sample follows the rotational scheme, which implies that a number of households remain in the sample (i.e they can be interviewed) for four consecutive years. The total sample for each year is divided into four independent and non-overlapping subsamples - the so-called rotational groups, equal in size and sample design, which represent the whole population. Every year, one rotational group from the previous year is excluded from the sample and a new rotational group is included in the sample.
18.2. Frequency of data
Once a year for a period of two months (April and May).
18.3. Data collection:Data collection in the Survey on Income and Living Conditions is done using face-to-face method, using a paper version of the questionnaire (PAPI method).
18.6. Adjustment:Not relevant.
