Sampling

When the Independent Verification Agency (IVA) moves to verify results of different DLIs in the field, it will take a representative sample of households, villages or water schemes, depending on the DLI in question, to ensure that the majority of results reported meet the criteria outlined for each indicator.

The DLIs on which sampling is applied are DLIs 2, 3, 4, 5 (5.1-5.3), 10.1, 10.2, 11 and 12 (12.1-12.3). The below table summarizes how samples are chosen for each DLI.

Sampling Methodology by DLI

DLI Observation Sampling Approach Sampling Unit Representative Level
DLI 2 Households provided with access to improved water services Simple Random Sampling (SRS) with Finite Population Calculation (FPC) considering the total number of households submitted with improved water access for each COUNTY Households County
DLI 3 Number of sustainably functioning water schemes Two stage sampling: SRS of water schemes with FPC on the schemes, followed by SRS with FPC of households. Water schemes, then Households Water schemes by County
DLI 4 Households provided with access to an improved sanitation facility Simple Random Sampling (SRS) with Finite Population Calculation (FPC) considering the total number of households submitted with improved sanitation access for each COUNTY Households County
DLI 5.1 Villages achieving Open defecation free status Two stage sampling: Census of villages in Year 2 submitted and passed QA per COUNTY. Then LQA for estimating corresponding households to be sampled in each village. Villages, then Households Villages by County
DLI 5.2 Villages that achieve community-wide sanitation status Two stage sampling: Census of villages submitted per COUNTY. Then LQA for estimating corresponding households to be sampled in each village. Census of all schools and Health Care Facilities submitted Villages, then Households and Institutions where applicable Villages by County
DLI 5.3 Villages that sustain community-wide sanitation status Two stage sampling: SRS of villages with FPC on villages submitted per COUNTY. Then LQA for estimating corresponding households to be sampled in each village. Villages, then Households and Institutions where applicable Villages by County
DLI 10.1 Number of households in the refugee camps, and in the host communities provided with access to improved water services under the Program Same as DLI 2 Households County
DLI 10.2 Number of households in the refugee camps, and in the host communities provided with access to an improved sanitation facility Same as DLI 4 Households County
DLI 11 Number of sustainably functioning water schemes in refugee-hosting Counties Same as DLI 3 Water schemes, then Households Water schemes by County
DLI 12.1 Villages in the refugee camps, and in the Host communities achieving ODF status Same as DLI 5.1 Villages, then Households Villages by County
DLI 12.2 Villages in the refugee camps, and in the Host communities achieving CWS status Same as DLI 5.2 Villages, then Households and Institutions where applicable Villages by County
DLI 12.3 Villages in the refugee camps, and in the Host communities sustaining CWS status Same as DLI 5.3 Villages, then Households and Institutions where applicable Villages by County
