Guidance on how to identify and treat double counting during PIIRS data reporting

  • When it is possible to quantify and deduct the double counting between projects/initiatives:
    • Map/Make a list of all the projects/initiatives reporting in PIIRS this FY.
    • Identify all those projects/initiatives that overlap (work with the same population and in the same location, having overlap on reach data and/or impact/outcomes data).
    • Quantify and deduct the double counting between the overlapping projects/initiatives. Doing this from the beginning of the PIIRS reporting process helps you ensure that the data reported in the individual reach forms from each project is no longer carrying double counting.
    • Fill REACH or IMPACT/OUTCOMES forms for each project, considering the analysis of double counting. See examples here below on how different countries have identified overlap between projects/initiatives and arrived at figures that do not carry double counting:

Examples assessing double counting in India, Ethiopia, Niger,
Yemen and Zimbabwe


  • When it is NOT possible to quantify and deduct the double counting between projects/initiatives:

Option 1:
    • Map/Make a list of all the projects/initiatives reporting in PIIRS this FY.
    • Identify all those projects/initiatives that overlap (work with the same population and in the same location, having overlap on reach data and/or impact/outcomes data)
    • Identify the largest/most representative project/initiative from all of those projects/initiatives that overlap and use it as "umbrella" in the reporting.
    • For REACH: Fill REACH forms for each one of the overlapping projects BUT, when reporting figures, do the following:
      • Only report REACH data for the largest/most representative project-initiative
      • Report the REACH figures for the smaller projects-initiatives as zero, making sure to leave a note explaining that participants are zero because they are already being reported under the largest/most representative one.
    • For IMPACT/OUTCOMES: Fill IMPACT/OUTCOMES forms for all overlapping projects that have gone through an evaluative process in the FY and have generate impact/outcomes data BUT make sure to indicate if the evidence reported presents potential double counting.


Option 2:
    • Map/Make a list of all the projects/initiatives reporting in PIIRS this FY.
    • Identify all those projects/initiatives that overlap (work with the same population and in the same location, having overlap on reach data and/or impact/outcomes data)
    • Group the overlapping projects and report them collectively under one REACH and one IMPACT/OUTCOMES form only. This will help you eliminate the risk of duplicating figures of participants if each project reported data individually. The FY18 REACH form itself includes more guidance on how to report data in the different sections of the form, when you group projects/initiatives.
