MMM Resource

This resource calculates the sample size required for all the different methods of estimating maternal mortality and helps the user understand

  1. the most suitable methods
  2. the relative cost of each approach and

For each country, you can populate the tables with default values which were generally obtained from UN sources or are standard defaults. Alternatively, you can overwrite any of these values if you have better data or want to experiment with alternative options. For example, we have entered the population of Afghanistan as 26,088,000 but you can change this value. We have also put the default level of confidence as 1.96 (95% confidence) but this can be changed to 1.65 for example (90% confidence).

Choose the country in which your research is to be undertaken and the desired level of precision. You will have the option to override the default values.
