Survey of Water, Sanitation, and Hygiene for Households and Schools 2017
This study provides Microdata for household and school surveys collected to support the 2017 Poverty Diagnostic of the Drinking Water, Sanitation and Hygiene (WASH) Sector. The diagnostic aimed to assess and visualize drinking water, sanitation, and hygiene service conditions of communities and households in the bottom 40 percent of the income distribution.
The primary survey data comes from two nationally representative surveys that were carried out for this study. The Household WASH Survey and the School WASH Survey covered about 3,000 households and 300 primary/secondary schools, respectively, and were conducted in the same primary sampling units following a household listing exercise. The school survey covers basic WASH conditions in schools, whereas the household survey contains information on the availability and quality of WASH services, costs incurred for meeting WASH needs, the health and other impacts on household wellbeing, and willingness to pay for improved services.

- Households: Standard stratified 2-stage random sampling.
- Sampling frame: 2010 national Census.
- Schools: Two selected on the basis of catchment areas in which selected PSUs fall.
- The survey included an intended 3000 households (3052 actually interviewed) from 150 primary sampling units (PSUs), and 300 schools (302 actually included).
Separate survey weights for each of the samples were calculated and merged with the survey data. Separate weights (adjusted for the PSU size using the results from the listing) were calculated for: (i) the main household sample weights; (ii) weights for the selected drinking water testing sample; (iii) weights for the selected water source testing sample; (iv) weights for the integrated Nutrition/WASH survey sample; and (v) weights for the selected schools sample.
The weights for households were based on the size of the population by strata projected by the Statistics Agency under the President of the Republic of Tajikistan (TajStat) for 2016, updated with PSU-level population estimates from the listing exercise. The weights for schools were assigned on the basis of the number of schools by region according to the official Education Management Information System (EMIS) database maintained by the Ministry of Education.

Mode of data collection
Computer Assisted Personal Interview [capi]
The survey instrument covered a range of information for the calculation of household welfare status, access to water and sanitation services, and practices relating to hygiene. It covered nine modules: (i) key demographic characteristics; (ii) housing and infrastructure; (iii) recall (one-week) of household food consumption and expenditure; (iv) consumption and expenditure on nonfood items; (v) water supply; (vi) sanitation facilities; (vii) hygiene practices; (viii) health issues; and (ix) water cleanliness testing at site of consumption/water source (for a subsample).
The School WASH Survey likewise gathered information regarding the status of WASH-related services and practices for a nationally representative sample. The instrument covered eight modules: (i) key school-level characteristics; (ii) information on the available water supply; (iii) self-assessed water quality and safety; (iv) sanitation and hygiene infrastructure; (v) education on hygiene; (vi) menstrual hygiene; (vii) water-borne illnesses; and (viii) water cleanliness testing at site of consumption/water source (for a subsample).
