2 possible metrics

  • 2 possible metrics

    • Wealth Index
    • Progress out of Poverty Index (PPI)
  • Piloting process

  • Results from pilots

  • Lessons learned from pilot

  • Reflections on the 2 metrics

  • Next steps


  • Why?

  • What?

    • Providing services in relation to economic need
    • Not other aspects of societal equity, such as age or gender
  • How?

    • Wealth index based on Demographic & Health Surveys(DHS)
    • PPI
    • Using client exit interviews

Working group teleconferences

  • Working group teleconferences

  • Small group meeting in March 2011

  • Feasibility study of wealth index method

  • Proposal of PPI

  • Agreement to test 2 methods where possible

  • Small group meetings and teleconferences in future

Initially used within DHS surveys

  • Initially used within DHS surveys

  • Ranks households in a nationally representative sample according to observable indicators of wealth

  • Ranks clients within the national distribution of wealth

  • Assigns clients to a wealth quintile, based on cut-offs within the national distribution

  • Proportion of clients in each wealth quintile

Developed by Grameen Foundation for service delivery organizations (i.e microfinance)

  • Developed by Grameen Foundation for service delivery organizations (i.e microfinance)

  • Correlates Income or Expenditure to 10 observable indicators from a national survey such as LSMS

  • Assigns weights to relevant values of the indicator

  • Likelihood that a client falls below established poverty line (national; $1/day; $2/day)

  • Proportion of clients below poverty line

3 organizations: World Health Partners, MSI, PSI

  • 3 organizations: World Health Partners, MSI, PSI

  • Included wealth index and/or PPI questions into previously scheduled client exit interviews

  • Data analysis conducted by study presenters

  • Pilot objectives:

    • Assess each metric individually for ease of implementation
    • Compare metrics with regard to data obtained and ease of implementation
    • Propose an aligned metric
    • Gather information to write a manual for implementation and analysis, that all franchises can use


  • Alignment

    • Lack of alignment meant that 2 metrics were tested
    • Only 1 country program able to test both to date
    • Theoretical difference: absolute or relative equity
  • Feasibility

    • In county implementation simple; no comments received on survey length
    • HQ researcher required for analysis; approx. 8 hrs per survey
    • DHS dataset or factor weights have to be requested
    • PPI only possible if questionnaire, weights, scoring table made available by Grameen Foundation

Wealth Index

  • Wealth Index


  • Alignment!

  • Agreement upon one measure

  • Dissemination of methodology and resources to calculate equity

  • Agreement upon the “metric”: Proportion of clients in the bottom 2 quintiles may not be informative for urban franchises
