Integrated Living Conditions Survey 2009 - 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.

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.

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.

摘要
---------------------------
由亚美尼亚共和国国家统计局（NSS）每年实施的综合性生活环境调查（ILCS），构成了监测亚美尼亚生活状况的基础。ILCS是一项被全球广泛认可的优良实践调查，旨在收集数据以反映家庭的生活水平。ILCS包含了关于家庭及个体福利的全面而宝贵的数据，这使得国家统计局有机会向公众提供有关人口收入、支出、贫困水平及其他生活水平年度变化的最新信息。

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，该数据库是在世界银行的技术援助下开发的。样本分为两部分：核心样本和超额样本。
1) 为了创建核心样本，抽样框架（包括亚美尼亚所有家庭地址的数据库）被划分为48个层级，包括12个埃里温市的社区。来自其他地区（marzes）的家庭根据三个类别进行分组：大型城镇（人口超过15,000），村庄和其他城镇。大型城镇由16个组（层级）组成，而村庄和其他城镇各由10个层级组成。根据这种划分，一个在marz层级上进行随机两步分层抽样的样本被开发出来。所有marzes以及所有城市和农村定居点均根据居住在这些定居点的家庭在国内外家庭总数中的比例被纳入样本人口。在第一步中，使用PPS方法选择枚举单位（即当年要调查的初级抽样单位）。2007年的样本包括每月48个城市和18个农村的枚举区域。
2) 超额样本是从包括在MCA-Armenia农村道路修复项目中的村庄名单中抽取的。那些已经在核心样本中的村庄的枚举区域被排除在该名单之外。从剩余的枚举区域中每月选择18个枚举区域。因此，农村样本量翻倍。
3) 在第二步中，合并核心样本和超额样本后，选择了调查家庭。每月调查656户家庭，其中来自城市的368户和来自农村的288户。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户家庭。2007年调查的家庭数量为7,872户（其中4,416户来自城市，3,456户来自农村地区）。
2009年，调查覆盖了45个城市和313个农村地区，样本量为7,872户。
