Source of data
All the data we use comes from DHS or MICS. Most of you probably already know these surveys, but they monitor data for a wide range of indicators in the area of population, health, nutrition, etc.
The reason we chose these surveys is because the data is uniform for the most part and we can easily compare data points across countries. The data is also easily accessible, it normally only takes a few days to access the data. And lastly, the surveys include a rich set of questions on health, demographic, and basic socioeconomic data that is available at the household and individual level.
These surveys are available for 29 countries in the Asia Pacific region which also allows for regional comparability.
