The Integrated Survey of Living Standards (ISLS) was introduced in Armenia in 1996, followed by the one in 1998-1999; thereafter, it has been conducted every year since 2001. Starting from 2004 the survey was renamed to The Integrated Living Conditions Survey (ILCS).
Since 1996, when the survey was first implemented in Armenia, the National Statistical Service of the Republic of Armenia (NSS) with the assistance of the World Bank, USAID and other donor organizations, has been putting efforts to continuously improve the quality of data collected through household surveys, as well as to advance its own expertise in arriving at a more accurate assessment of poverty. These efforts have proven to be successful as the data collected through household surveys and the estimates of poverty based on such data became an important input in defining and monitoring the poverty reduction strategy, which is the responsibility of the Government.
In 2004, the NSS implemented significant changes to improve the Integrated Living Conditions Survey and to update the poverty assessment methodology, which was used until 2008. With the technical assistance provided by the World Bank: (1) the survey sample frame was updated using the 2001 Population Census frame, (2) the sample size was expanded to ensure representativeness of data by regions, (3) the ILCS questionnaire was revised to reflect economic and social changes between 1998/99 and 2003, as well as a comprehensive section on employment was added into the questionnaire, (4) the interviewers underwent a more profound training.
With the co-funding provided within the period of 2007-2011 by the Millennium Challenge Account - Armenia (MCA-Armenia), a state non-commercial organization, the sample size of the ILCS has been expanded to include 7,872 households annually as compared to 5,184 households in 2006 (funded from the state budget only). When activities of MCA-Armenia came to an end in 2012, the sample size was again reduced back to 5,184 households.
The ILCS is conducted during the year with monthly rotation of households and settlements. The survey results serve primarily to assess the level of consumption-based poverty in Armenia.
The Integrated Living Conditions Survey (ILCS), conducted annually by the NSS National Statistical Service of the Republic of Armenia, formed the basis for monitoring living conditions in Armenia. The ILCS is a universally recognized best-practice survey for collecting data to inform about the living standards of households. The ILCS comprises comprehensive and valuable data on the welfare of households and separate individuals which gives the NSS an opportunity to provide the public with up to date information on the population’s income, expenditures, the level of poverty and the other changes in living standards on an annual basis.

During the 2007-2012 surveys the sampling frame for ILCS was designed according to the database of addresses for the 2001 Population Census, which was developed with the World Bank technical assistance. The sample consisted of two parts: core sample and oversample.
1) For the creation of core sample, the sample frame (database of addresses of all households in Armenia) was divided into 48 strata including 12 communities of Yerevan city. The households from other regions (marzes) were grouped according to three categories: large towns (with population of 15000 and higher), villages and other towns. Large towns formed by 16 groups (strata), while the villages and towns formed by 10 strata each. According to that division, a random, two-step sample stratified at the marz level was developed. All marzes, as well as all urban and rural settlements were included in the sample population according to the share of households residing in those settlements as percent to the total households in the country. In the first step, using the PPS method the enumeration units (i.e., primary sample units to be surveyed during the year) were selected. 2007 sample includes 48 urban and 18 rural enumeration areas per month.
2) The oversample was drawn from the list of villages included in MCA-Armenia Rural Roads Rehabilitation Project. The enumeration areas of villages that were already in the core sample were excluded from that list. From the remaining enumeration areas 18 enumeration areas were selected per month. Thus, the rural sample size was doubled.
3) After merging the core sample and oversample, the survey households were selected in the second step. 656 households were surveyed per month, from which 368 from urban and 288 from rural settlements. Each month 82 interviewers had conducted field work, and their workload included 8 households per month. In 2007 number of surveyed households was 7,872 (4,416 from urban and 3,456 from rural areas).
In 2009 the survey covered 45 urban and 313 rural areas with the sample size of 7,872 households.
Dates of Data Collection
Data Collection Mode
The Questionnaire is filled in by the interviewer during the least five visits to households per month. During face-to-face interviews with the household head or another knowledgeable adult member, the interviewer collects information on the composition and housing conditions of the household, the employment status, educational level and health condition of the members, availability and use of land, livestock, and agricultural machinery, monetary and commodity flows between households, and other information.
The 2009 survey questionnaire had the following sections: (1) "List of Household Members", (2) "Migration", (3) "Housing and Dwelling Conditions", (4) "Employment", (5) "Education", (6) "Agriculture", (7) "Food Production", (8) "Monetary and Commodity Flows between Households", (9) "Health (General) and Healthcare", (10) "Debts", (11) "Subjective Assessment of Living Conditions", (12) "Provision of Services", (13) "Social Assistance", (14) "Households as Employers for Service Personnel", and (15) "Household Monthly Consumption of Energy Resources".
The Diary is completed directly by the household for one month. Every day the household would record all its expenditures on food, non-food products and services, also giving a detailed description of such purchases; e.g. for food products the name, quantity, cost, and place of purchase of the product is recorded. Besides, the household records its consumption of food products received and used from its own land and livestock, as well as from other sources (e.g. gifts, humanitarian aid). Non-food products and services purchased or received for free are also recorded in the diary. Then, the household records its income received during the month. At the end of the month, information on rarely used food products, durable goods and ceremonies is recorded, as well. The records in the diary are verified by the interviewer in the course of 5 mandatory visits to the household during the survey month.
The Survey Diary has the following sections: (1) food purchased during the day, (2) food consumed at home during the day, (3) expenditures on food consumed away from home, (4) non-food products purchased and services obtained, (5) non-food products and services received free of charge, (6) household income and monetary inflows, (7) food products, which are usually consumed in small quantities during the day, (8) list of real estate, durable goods, and ceremonies. The interviewer’s manual provides detailed instructions for completing the questionnaire and the diary.
The Questionnaire, the Diary and the Interviewer's Manual are revised and adjusted, as appropriate, prior to the launch of the survey. Starting from 2012, data are codified under the "Classification of Individual Consumption by Purpose" (COICOP) classifier.
