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

The sample was based on a revised national master sample that has been developed out of the 2002 Census information. For the 2007 HBS, the national master sample provided the primary sampling units (PSUs) for the national urban and rural sample. It was supplemented with additional PSUs to provide a regional sample for Dar es Salaam, so that the survey provides estimates for Dar es Salaam region, other urban areas and rural areas.

Primary sampling units were selected using probability proportional to size, with the number of household recorded in the Census preparatory estimates being the measures of size. A comprehensive household listing was undertaken in each of the sampled clusters. Information on a number of household durable assets was collected for each household during the household listing exercise. This information was used to stratify households within each cluster into high, middle and low income households. Separate proportional samples were then drawn from each of these categories. The sample selection was done in the head office and each regional supervisor was supplied with their respective list of pre-selected households.

抽样程序
---------------------------
本样本基于从2002年人口普查信息中发展而来的修订版国家主样本。对于2007年家庭调查（HBS），国家主样本为国家城市和农村样本提供了初级抽样单位（PSU）。为提供达累斯萨拉姆地区的区域样本，补充了额外的PSU，以确保调查能够为达累斯萨拉姆地区、其他城市地区和农村地区提供估计值。
初级抽样单位采用与规模成比例的概率进行选择，以普查准备估计中记录的家庭数量作为规模的衡量标准。在每个抽样簇中进行了全面的 household 列表编制。在 household 列表编制过程中，收集了关于众多 household 持久性资产的信息。这些信息被用于将每个簇内的家庭分层为高收入、中等收入和低收入家庭。然后，从每个类别中分别抽取了成比例的样本。样本选择在总部进行，每个区域总监都得到了其各自预选 household 的名单。
