 So NPM is basically Needs and Population Monitoring. We are here to collect regularly information on population, locations and the multi-sectoral needs and gaps of the Rohingya population here in Cox Bazar, Bangladesh. We're doing this every month so we keep updating our data and this data is used directly by all the humanitarian actors on the ground in order to plan the resistance or to coordinate their activities. Basically they are in the blocks. We have some block leaders in local language we call as MAJIS. So basically those MAJIS are directed where to go and where not to go. We direct them. So after that the MAJIS took them to the place they want to go. The last time we did the assessment was in October and then we managed to identify a total population of close to 800,000 of Rohingya population in Cox Bazar district. On the other hand NPM also track movement of the population. So we talk about cross-border movement from new arrivals directly coming from Myanmar to Cox Bazar as well as the internal movement of population moving between different sites or from the host community locations to the major sites where they could probably access better assistance. So IOM is doing like monitoring the movement because we need to inform the other agency like our partners that this number of people are waiting so that they can be also prepared and provide the assistance. So that is our main purpose and as a part of NIS and population monitoring or like generally we say DTM. So we track the movements so we are also here tracking the movements of the people. This is the voice of the communities how they see what their needs are and what are the gaps. And this information feed directly the operations on the ground basically.
