		Dear all, 
 
I am using the DHS database for the first time and also I have never worked with survey data before. My aim is a bit broad, it is to understand which variables have an impact on child mortality/under five mortality. 
 
In order to achieve my aim I need to combine datasets from different countries for different year and build a pooled database. 
 
And, this is the first problem I face -- I don't know how to combine databases from different countries for different year. Do I need to add a weight? If yes, how do I calculate this weight and how do I take it into account? Or take another factor into account. 
 
I do understand that my question is a bit naive but if anyone could point me in the right direction, that would be simply great..!!!! 
 
Many thanks..!!! 
 
Regards 
Kinsuk
