Table 2 Two key issues to clarify prior to measuring maternal mortality

   • To generate a broad estimate of the magnitude of the problem

   • To identify detailed causes, differentials and determinants

   • To identify differences in levels within a country

   • To permit cross-country comparisons

   • To enable regular monitoring of progress

What resources are available?

   • Existing data sources or data-collection opportunities, for example routine civil registration, large multi-purpose surveys

   • Human resources, for example technical skills to design a survey, or to manage, analyse and interpret data

   • Field budget, for example funds available for new data collection

   • Time available, for example estimate needed immediately, in 1–2 years time, or longer
