REACH Khulna Household Survey, 2018

The REACH Khulna Household Survey was conducted between December 2017 and February 2018 to collect quantitative data on various indicators of multidimensional poverty, the state of drinking water services and vulnerability to water-related hazards. The survey was carried out in Polder 29, one of the 139 polders (embanked islands) in southwestern coastal Bangladesh. Polder 29 has a land area of 80 km2 and covers five unions (Tier-4 administrative boundary) across Dumuria and Batiaghata upazilas (sub-districts) of Khulna district. The polder is further sub-divided into 77 mouzas (Tier-5 administrative boundary), with a total population of 58,000 and 17,000 households (BBS, 2011). The survey was administered to 2103 households in two stages: phase 1 involved 978 households spatially distributed across the polder, while phase 2 involved 1125 households within 16 chosen mouzas with relatively higher risk profiles. A stratified random sampling method was used to allocate equal proportions of households from each mouza. During the survey, enumerators used a ‘random route/walk sampling’ technique, where households were selected at certain intervals, determined by the total number of households in the mouza, the sample size per mouza, and the settlement patterns. The survey was administered in Bangla through an electronic form developed in ONA (https://ona.io/), and was conducted by 15 trained local enumerators.
