In preparing a disaster risk profile for a country like Nigeria, How do you deal with data from different databases and other sources which gives you different figures of displacement, mortality, fatality, etc
There is no easy answer to your question - disaster data is very challenging to work with. There are several factors that need to be assessed, including the quality of the data gathering, what methodology was used, how indices are defined, potential biases within the organization that gathered the data, and what metric is being used. For the latter for example, total fatalities give a very different picture than fatalities normalized by population size. Resolving issues of differences requires an in-depth analysis that addresses all these factors.
I am attaching a UNDP paper that you might find helpful. Good luck!
I was working at Disaster Info. Lab at NIED in Japan. Collect the data as much as possible from reliable sources. Then we can see the common picture even if there are some differences. Going to the field is preferable to comfirm that.This is my first opinion. Thank you.
