Household Budget Survey 2005 - Azerbaijan

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

The Household Budget Survey conducted by the State Statistical Committee of the Republic of Azerbaijan is the main source of information for analysis of living standards of separate population groups, income differentiation and poverty levels in the country. The survey was introduced in 2001 and has been carried out annually since then.

The Azerbaijan HBS is based on a random probability sample, which was designed to give nationally representative results and allow comparison between main regions of the country and different categories of the population. Approximately 8,700 households are interviewed annually. The annual sample is divided into about 2,200 households per quarter, with a full rotation of households occurring each quarter.

The survey collects information on household income and expenditure, housing conditions, ownership of consumer durables, access to agricultural land and demographic characteristics of household members.

- Private households.

A household is defined as a single person or a group of persons with a common budget and residence (house, flat, etc.). The members of the household may not be relatives even if living together and sharing a common household. Persons living in institutional households (elderly houses, hospitals, military barracks etc.) are excluded from the survey.

Since the first half of 90-ties about 800,000 persons migrated within Azerbaijan because of the war in Nagorno-Karabach region. There have been some 250,000 refugees mainly from the other republics of previous USSR, too. This population part is included in the sampling frame according to their actual living place at the time of the population census in 1999.

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

The sample of Azerbaijan HBS is based on territorial random probability principles. This allows stratifying the population by urban/rural category and by geographical characteristics (eight regions - economic zones). Taking into account that one fourth of the population is concentrated in the capital city Baku this population was included into a separate stratum.

Data from the population census 1999 was used in the survey. Three-stage sampling was implemented to select participating households.

Detailed description of the sampling procedure is available in "Azerbaijan HBS: Methodology" (p.2-6) in external resources.

摘要
---------------------------
由阿塞拜疆共和国国家统计委员会执行的《家庭预算调查》是分析该国不同人口群体生活水平、收入差异和贫困水平的主要信息来源。该调查于2001年启动，自此每年进行一次。

阿塞拜疆家庭预算调查基于随机概率样本设计，旨在提供全国代表性结果，并允许对国家主要地区及不同人口类别进行比较。每年约有8,700户家庭接受调查。年度样本分为约每季度2,200户，每季度进行全面的家庭轮换。

调查收集了关于家庭收入和支出、住房条件、耐用消费品所有权、农业用地获取以及家庭成员人口特征的详细信息。

地理覆盖范围

全国

分析单元
---------------------------
- 私人家庭。
家庭被定义为具有共同预算和居住地（房屋、公寓等）的单一个人或一组人。即使家庭成员共同居住并共享共同的家庭预算，家庭成员也不一定是亲属。居住在机构家庭（养老院、医院、军事营房等）的人被排除在调查之外。
自90年代中期以来，约80万人因纳戈尔诺-卡拉巴赫地区的战争而在阿塞拜疆境内迁移。此外，还有约25万人主要来自前苏联的其他共和国。这部分人口根据他们在1999年人口普查时的实际居住地被纳入抽样框架。

数据类型

样本调查数据 [ssd]

抽样程序
---------------------------
阿塞拜疆家庭预算调查的样本基于地域随机概率原则。这允许根据城市/农村类别和地理特征（八个地区-经济区）对人口进行分层。考虑到四分之一的人口集中在首都巴库，这部分人口被纳入一个单独的层级。
在调查中使用了1999年人口普查的数据。实施了三阶段抽样来选择参与家庭。
抽样程序的详细描述见外部资源中的“Azerbaijan HBS：方法论”（第2-6页）。
