      1. The main objectives of the HBS are in the first place to provide basic data required for policy making at national levels and for different sectors. Secondly, the survey will facilitate the determination of needs or the establishment of targets which can be identified as follows: • Obtaining the data needed to estimate the weights used for calculating the consumer price index (CPI). • The data used as input for measuring private household consumption in national accounts (NA). • The data for the analysis of welfare and poverty at the country level within the specified time frame. The main characteristics of the data set are are: - Consumption Expenditure - Income - Housing.
      1. The HBS collects information on Consumption Expenditure according to the Classification of Individual Consumption by Purpose (COICOP - 5 digit level from 2015), International System of Classification of Occupations (ISCO 88), The European Classification of Economic Activities (NACE Rev.2) and International System of Classification of Education (ISCED 97).
      1. Statistics covers household sector by consumption expenditure, income and living conditions, for Price sector (for calculating the consumer price index CPI), for National Account sector (as input for measuring private household consumption in national accounts NA).
      1. Providing data for household Consumption, Expenditure, Living conditions, Income and Poverty. Consumption - Agriculture goods consumed own products and from gifts. Expenditure - goods buy (for food, drink, clothing, textile, transport, restaurants, books, education, housing, health, recreation. Living conditions - housing, affordability. Income - from public and private sector, per diem, social benefits, pensions, own business, remittances, gifts. Poverty - Absolute and Food poverty. Data collected through HBS also provide information on living standards, the measure and the composition of total consumption and expenditure of families and their socio-economic characteristics.
      1. Households and household members.

      1. KAS is committed to quality assurance in the production of official statistics. Based on the "Law On Official Statistics, Law 04 / L-036", KAS uses statistical methods and processes in accordance with internationally accepted scientific principles and standards and conducts ongoing analyzes in order to improve the quality and delivery of updated statistics. In carrying out its duties, KAS follows the overall quality management principles, in line with the European Statistics Code of Practice. KAS has developed a Quality Statement which is available on the KAS website: . The document lists eleven principles, much in line with the CoP principles like professional independence and statistical confidentiality, on which the work of KAS is based.

      1. During July 2017, in Kosovo Agency of Statistics was conducted the process of assessment of the Kosovo Statistical System through the “Peer Review” approach.
      1. The main objectives of the HBS are in the first place to provide basic data required for policy making at national levels (Ministry of Labour, Ministry of Social Welfare, Government, Ministry of Education, University, students in Master and Phd degree). Secondly, the survey will facilitate the determination of needs or the establishment of targets which can be identified as follows: •Obtaining the data needed to estimate the weights used for calculating the consumer price index (CPI). •The data used as input for measuring private household consumption in national accounts (NA). •The data for the analysis of welfare and poverty at the country level within the specified time frame.
      1. One of the key elements to ensure the quality of statistical data is the measurement of the satisfaction of users. The survey aims to gather comprehensive information on the needs and requirements of users of official statistical data. Through this survey the users of statistical data have expressed their thoughts and opinions regarding statistical views, they have provided advice and suggestions regarding their needs for statistics and how to improve these statistical data in the future. This survey was conducted during the conference held with the users of statistical data, in which 11 users responded. The questionnaire contained eight questions and included various topics: the use of statistical data, evaluation of KAS in general, the assessment of the site in KAS, evaluating the quality of statistical data, etc. More detailed information on this survey can be found on the web: .
      1. Each survey conducted by KAS is based on a sample selection to draw the conclusions in the study about the population. Naturally, this process is accompanied by statistical deviations. For this reason, the standard deviations of the choice used for interpreting the results of the survey were calculated.
      1. The sampled households are used to calculate estimates of the expenditure (etc.) for all households. If the sample is big enough, and selected in a scientific way, the uncertainty of the estimates will generally be small. The uncertainty is often expressed by a confidence interval. The true value for the entire population is then expected to be somewhere between the lower and the upper confidence limit, with a high probability (here 95 %). The confidence intervals for some of the main variables in HBS are shown in table 1 in Annex.
      1. Unit non response takes into account families that are unable or ready to respond, or when interviewers are unable to find families, or when other obstacles exist to complete the interview. The rate of non-response, also based on the replaced economies, is 22.0%.
      1. Reference year - from 1st January 2015 till 31th December 2015 Timeliness -11 June 2014. * The survey started by June 2002..
      1. Delay time is 0.
      1. Statistics refer to the local and national level.
      1. There are no breakdowns in time series.
      1. HBS annual data are used for weight structure for the CPI, in National account sector for calculating of GDP (GDP by expenditure approach). HBS is following every change in classifications and definitions in those statistical domains.
      1. The internal consistency of the data is checked before it is finalized. The links between the variables and the coherence in their series is also checked. The data are coherent in the internal aspect.
      1. HBS interviewers by full time -14 in 7 regional offices. HBS interviewers by contract - 4 (for Serbs area). Persons doing logical control and putting material in data entry - 2. Persons doing checking after data entry, producing tables and publications - 3 200 household are interviewed every month = 2400 per year. The time spent in household approximately 15 minutes during the first visit, 1 hour during the second visit, also 1 hour during the last visit. Beside this household need to fill in the Dairy of expenditures during two weeks, the time spent is difficult to estimate.
      1. There is no revision policy at KAS.
      1. No revisions have been carried out.
      1. The data set is based on survey. The sampling frame was based on the data and cartography from the 2011 Kosovo Census. For the purposes of the census enumeration, Kosovo was subdivided into enumeration areas (EAs), which are relatively small operational segments defined for the census enumeration. A total of 4,626 EAs were defined for Kosovo, and these were used as the primary sampling units (PSUs) selected at the first sampling stage for the HBS. A total of 300 sample EAs were selected for HBS 2015 Kosovo. Within each sample EA 8 sample households were selected at the second stage, for a total sample size of 2,400 per year. Budget Survey, stratified 300 EA (by 7 region and urban/rural).
      1. The data collection is monthly.
      1. To collect the data for interview it was used Paper-Assisted Personal Interview (PAPI). The questionnaires are: mainly for household and Diary for food and drink goods. The reference periods are given bellow: Diary for food and drink - for 2 weeks, Non-food - for 3 months, Durable goods - for 12 months, Gifts received - for 1 month, Income - for 12 months, Agriculture (sold and produced goods and expenditure) - for 1 month.
      1. Calculation of basic weights: The basic weight for each sample household would be equal to the inverse of its probability of selection (calculated by multiplying the probabilities at each sampling stage). A household weight will be attached to each sample household record in the data files. The sampling probabilities at each stage of selection should be maintained in an Excel spreadsheet with information from the sampling frame for each sample EA, so that the overall probabilities and corresponding weights can be calculated. The probabilities of selection are based on the stratified two-stage sample design. At the first stage a sample of EAs was selected with equal probability within each stratum (region, urban/rural), and at the second stage a sample of 8 households was selected in each sample EA. Adjustment of 2013 HBS Weights Based on Population Projections: Therefore it was decided to adjust the HBS weights using the projected total population of Kosovo for mid-2013 based on demographic techniques. This will also make the weighted estimate of the total population using the annual weights consistent with the projected total population.
