      Technical notes:

      The standard simplification process was applied to achieve high agreement with the original wealth index. Kappa was greater than 0.75 for the national and urban indices. Details on the standard process can be found in this article. The data used to identify important variables comes from the factor weights released by ICF.

      Additional questions/response options were added to the tool to improve the differentiation between the two poorest quintiles, but users should be advised that the differentiation between those quintiles is not as good as is achieved by most other EquityTools. If differentiation is between the poorest and second poorest quintiles is important for your project, please contact support@equitytool.org.

       

      Level of agreement:

      National Population

      (n=4909)

      Urban only population

      (n=1660)

      % agreement 86.6% 84.2%
      Kappa statistic 0.791 0.753

       

      Respondents in the original dataset were divided into three groups for analysis – those in the 1st and 2ndquintiles (poorest 40%), those in the 3rd quintile, and those in the 4th and 5th quintiles (richest 40%). After calculating their wealth using the simplified index, they were again divided into the same three groups for analysis against the original data in the full DHS. Agreement between the original data and our simplified index is presented above.

       

      What does this mean?

      When shortening and simplifying the index to make it easier for programs to use to assess equity, it no longer matches the original index with 100% accuracy. At an aggregate level, this error is minimal, and this methodology was deemed acceptable for programmatic use by an expert panel. However, for any given individual, especially those already at a boundary between two quintiles, the quintile the EquityTool assigns them to may differ from their quintile according to the original DHS wealth index.

      The graph below illustrates the difference between the EquityTool generated index and the full DHS wealth index. Among all of those people (20% of the population) originally identified as being in the poorest quintile, approximately 59.0% are still identified as being in the poorest quintile when we use the simplified index.  However, approximately 36.6% of people are now classified as being in Quintile 2. From a practical standpoint, all of these people are relatively poor. Yet, it is worthwhile to understand that the simplified index of 12 questions produces results that are not identical to using all 40 questions in the original survey.

      Data interpretation considerations:

      1. This tool provides information on relative wealth – 'ranking' respondents within the national or urban population. The most recent available data from the WorldBank indicates that 51.1% of people in Togo live below $1.90/day[1]. This information can be used to put relative wealth into context.
      2. People who live in urban areas are more likely to be wealthy. In Togo, 47.0% of people living in urban areas are in the richest national quintile, compared to only 3.4% of those living in rural areas[2].
        1. If your population of interest is predominantly urban, we recommend you look at the urban results to understand how relatively wealthy or poor they are, in comparison to other urban dwellers.
        2. If the people you interviewed using the EquityTool live in rural areas, or a mix of urban and rural areas, we recommend using the national results to understand how relatively wealthy or poor they are, in comparison to the whole country.
      3. Some regions in Togo are wealthier than others. It is important to understand the country context when interpreting your results.
      4. In most cases, your population of interest is not expected to be equally distributed across the five wealth quintiles. For example, if your survey interviewed people exiting a shopping mall, you would probably expect most of them to be relatively wealthy.
