Integrated Living Conditions Survey 2008 - Armenia

Abstract
---------------------------

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. 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.

Sampling procedure
---------------------------

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. For the creation of core sample:

1) 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 2008 the survey covered 44 urban and 263 rural areas with the sample size of 7,872 households.

由亚美尼亚共和国国家统计服务局（NSS）每年进行的综合生活条件调查（ILCS）构成了监测亚美尼亚生活条件的基础。ILCS是一项全球公认的最佳实践调查，旨在收集数据，以反映家庭的生活水平。ILCS包含了关于家庭和个体福利的全面且宝贵的数据，这使得国家统计服务局有机会每年向公众提供关于人口收入、支出、贫困程度以及其他生活水平变化的最新信息。在2007-2011年期间，由千年挑战账户亚美尼亚（MCA-Armenia）这一国家非营利组织提供联合资助下，ILCS的样本规模得到了扩大，每年包括7,872个家庭，相较于2006年的5,184个家庭（仅由国家预算资助）。当MCA-Armenia的活动于2012年结束时，样本规模再次减少至5,184个家庭。

抽样程序
---------------------------
在2007-2012年的调查期间，ILCS的抽样框架是根据2001年人口普查的地址数据库设计的，该数据库在世行技术援助下开发。样本分为两部分：核心样本和过度样本。核心样本的创建过程如下：

1) 样本框架（亚美尼亚所有家庭的地址数据库）被划分为48个层，包括12个埃里温市的社区。其他地区（marzes）的家庭根据三个类别分组：大型城镇（人口15,000以上）、村庄和其他城镇。大型城镇由16个组（层）组成，而村庄和其他城镇各由10个层组成。根据这种划分，开发了在marz层进行分层随机两步样本。所有marzes，以及所有城市和农村定居点都包括在样本人口中，根据居住在这些定居点中的家庭占全国总家庭数的百分比。在第一步中，使用PPS方法选择了普查单位（即当年要调查的初级样本单位）。2007年的样本包括每月48个城市和18个农村普查区域。

2) 过度样本是从MCA-Armenia农村道路修复项目包括的村庄列表中抽取的。已在核心样本中的村庄普查区域被排除在该列表之外。从剩余的普查区域中每月选择18个普查区域。因此，农村样本规模翻倍。

3) 在第二步中，合并核心样本和过度样本后，选择了调查家庭。每月调查656个家庭，其中368个来自城市定居点，288个来自农村定居点。每月有82名访谈员进行实地工作，他们的工作量包括每月8个家庭。2007年调查的家庭数量为7,872个（4,416个来自城市地区，3,456个来自农村地区）。

2008年，调查覆盖了44个城市和263个农村地区，样本规模为7,872个家庭。
