Changing Food Consumption of the Households in Developing Countries: A Bangladesh Case

The dataset primarily consists of Bangladesh’s Household Income and Expenditure Survey (HIES) data collected in 2000, 2005 and 2010 by the Bangladesh Bureau of Statistics (BBS). The BBS uses a two-stage stratified random sampling to ensure maximum precision in the data collection process in each survey round. In the first stage, the BBS selects primary sampling units (PSUs) consisting of specific geographical areas, and in the second stage, it randomly selects 20 households from each PSU that represent rural, urban, and statistical metropolitan areas (SMAs). The present study is based on information collected from a total of 29,676 households surveyed in 2000, 2005 or 2010, of which 9,183 were from urban areas and the remaining 20,493 were from rural areas.
The HIES 2000, 2005 and 2010 data on household-level consumption is quite detailed. The consumption of food items in quantity and expenditure was divided into 17 major food categories and collected all consumption information for two-week period. The major categories were cereals, pulses, fish, eggs, meat, vegetables, milk and dairy products, sweets, oil and fats, fruits, drinks, sugar and molasses, tobacco and related items, spices, betel leaves and betel nuts. In the cereal category, there were sub-categories of rice, wheat, and processed rice and wheat products. As the major focus of this study is the examination of the trends of cereal consumption patterns over time by households in a rapidly-growing developing country, this study analyzed the consumption of five basic and commonly-consumed food items: rice and wheat (both including grain and processed products), pulses, fish and vegetables.

本数据集主要包含由孟加拉国统计局（Bangladesh Bureau of Statistics, BBS）于2000年、2005年及2010年采集的孟加拉国家庭收入与支出调查（Household Income and Expenditure Survey, HIES）数据。孟加拉国统计局在每一轮调查中均采用两阶段分层随机抽样方法，以保障数据采集过程的最高精度。第一阶段，统计局选取由特定地理区域构成的初级抽样单元（Primary Sampling Units, PSUs）；第二阶段，从每个涵盖农村、城镇及统计都市区（Statistical Metropolitan Areas, SMAs）的初级抽样单元中随机抽取20户家庭。本研究基于2000年、2005年及2010年共29676户受访家庭的采集信息，其中9183户来自城镇地区，剩余20493户来自农村地区。
2000年、2005年及2010年的HIES家庭层面消费数据极为详尽。食品消费的数量与支出被划分为17个主要食品类别，并采集了为期两周的全部消费相关信息。主要类别包括谷物、食用豆类、鱼类、蛋类、肉类、蔬菜、奶类及乳制品、糖果、油脂类、水果、饮品、食糖与糖蜜、烟草及相关制品、香辛料、槟榔叶与槟榔果。在谷物类别下，还包含大米、小麦及加工米麦制品的子类别。鉴于本研究的核心目标是探究快速发展的发展中国家家庭谷物消费模式随时间变化的趋势，本研究对五种基础且常见的食品的消费情况进行了分析：大米与小麦（均包含原粮及加工制品）、食用豆类、鱼类及蔬菜。
