Household Income and Expenditure Survey 2019 - Sri Lanka

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

This survey provides information on household income and expenditure to be able to measure the levels and changes in the
living condition of the people, to observe the consumption patterns and to compute various other indicators such as poverty,
food ratio, gini co-efficient of income and expenditure etc.
Key objectives of the survey
- To identify the income patterns in Urban, Rural, Estate Sector and Districts.
- To identify the income patterns by income levels.
- Average consumption of food items and non food items.
- Expenditure patterns by sector and by different income levels.
- To identify the incidence of poverty by sector and income levels

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

Sample design of the survey is two stage stratified and the Urban, Rural and the Estate sectors in each district of the country are the selection domains thus the district is the main domain used for the stratification. The sampling frame is the list of housing units prepared for the Census of Population and Housing (CPH) 2011.

Selection of Primary Sampling Units
Primary sampling units (PSUs) are the census blocks selected for the survey. The sampling frame, which is the collection of all the census blocks prepared in CPH 2011 in Sri Lanka, is used for the selection of the PSUs at the first stage of the selection.
The PSU selection is done within all the independent- selection domains that are assigned different sample size allocations to total the targeted sample size of 2,500 PSUs. The method of selection of the PSUs at the first stage is systematic with a selection probability given to each census block proportionate to the number of housing units available in the census blocks within the selection domains (PPS).
The selected PSUs are updated to include newly built housing units and to exclude demolished or vacated housing units, which are no longer considered as housing units according to the survey definitions, to capture variation of natural growth and to make necessary adjustments for the same. The PSU updating operation in field is generally done less than one month prior to the survey and it was carried out for the 12 months starting from October 2015 to September 2016 to support the scheduled 12 survey months started from January to December in 2016 for the HIES 2016.

Selection of Secondary Sampling Units
Secondary Sampling Units (SSUs) or Final sampling units (FSUs) are the housing units selected at the second stage from the 2,500 PSUs selected at the first stage. From each PSU, 10 SSUs (housing units) are systematically selected giving each housing unit in the PSU an equal probability to be selected for the survey. The total sample of size 25,000 housing units is resulted at the end of the sampling process and this sample represents the whole country in different probabilities depend on the different sample sizes allocated for the selection domains.

摘要
---------------------------
本调查旨在提供关于家庭收入和支出的信息，以便衡量人民生活水平的现状及其变化，观察消费模式，并计算各种其他指标，如贫困率、食品比、收入和支出基尼系数等。
调查的主要目标
- 识别城市、农村、住宅区和各地区的收入模式。
- 根据收入水平识别收入模式。
- 食品和非食品项目的平均消费。
- 各个部门和不同收入水平的支出模式。
- 识别贫困在各部门和收入水平中的发生率。

抽样程序
---------------------------
调查的样本设计为两阶段分层抽样，国家各地区的城市、农村和住宅区是选择域，因此地区是分层的主要域。抽样框架是针对2011年人口和住房普查（CPH）准备的住房单位列表。
一级抽样单元的选择
一级抽样单元（PSU）是为调查选择的普查区。抽样框架，即2011年斯里兰卡人口和住房普查（CPH）中准备的普查区的集合，用于在选择的第一个阶段选择PSU。
PSU的选择是在所有分配不同样本量分配的独立选择域内进行的，以汇总达到目标样本量2,500个PSU。一级阶段PSU的选择方法是系统性的，每个普查块被赋予的选择概率与选择域内普查块中可用的住房单位数量成比例（PPS）。
选定的PSU被更新以包括新建的住房单位，并排除已拆除或空置的住房单位，这些单位根据调查的定义不再被视为住房单位，以捕捉自然增长的变化，并对同一内容进行必要的调整。现场PSU更新操作通常在调查前不到一个月进行，并从2015年10月开始至2016年9月结束，以支持2016年1月至12月开始的为期12个月的HIES 2016的预定调查月份。
二级抽样单元的选择
二级抽样单元（SSU）或最终抽样单元（FSU）是在第一阶段选定的2,500个PSU的第二阶段选定的住房单位。从每个PSU中系统地选择10个SSU（住房单位），使PSU中的每个住房单位都有同等的机会被选入调查。抽样过程结束时，得到的总样本量为25,000个住房单位，该样本以不同的概率代表整个国家，这些概率取决于选择域的分配样本量。
