We have been making use of the FGM statistics from many of your reports. We are trying to compare FGM prevalence between different reports, to see how the overall prevalence of FGM has changed with time in a given country. I wondered if you could help me to understand the uncertainty on the prevalence rate, in order that we can understand whether we observe significant changes. For example in Kenya we observe a 23% fall in FGM prevalence from 2008-9 (27.1%) to 2014 (21%). However in Uganda we observe a 130% increase in FGM prevalence from 0.6% (2006) to 1.4% (2011).
I assume that there will be some statistical uncertainty from the sampling, and perhaps some systematic uncertainty perhaps e.g. from the way in which the surveys were carried out. I would be very grateful if someone could advise me on how to derive these uncertainties so we can understand the significance of the prevalence changes.
