Hi forum users,

Can we use the wealth score available as continuous variable?

gen asset=v191/100000

Just wanted to check if I need to be aware when using it in pooled survey from different years !! I am using Nepal DHS from 2001, 2006, 2011.

Any insights would be greatly appreciated.

Thanks,
Pnep

Dear User, Here is a response from one of our experts, Dr. Shea Rutstein:
Quote:
The DHS wealth index is calculated separately for each survey (with a couple of exceptions, not being Nepal) so that the value of the wealth score in one survey may not (usually the case) correspond to the same level of wealth in another survey even in the same country. For that, the Comparative Wealth Index was created. To create the Comparative Wealth Index for those surveys use the following:

CWI score=Alpha + Beta*v191
Country Year Constant (Alpha) Coefficient (Beta)

Nepal, 2001 -1.0876444 0.6696379
Nepal, 2006 -0.8041832 0.8550128
Nepal, 2011 -0.3603931 1.0388343

To create comparable quintiles, use these values as cutpoints:

Cut points for CWI quintiles:
1-2 -0.90802
2-3 -0.38583
3-4 -0.01189
4-5 0.74156

And yes, you can use the values of the CWI (and individual wealth index scores) instead of quintiles.

Hi Liz,

Many thanks for the reply and information. I believe this is the document which describes the process for obtaining the constant and coefficient. http://iussp.org/sites/default/files/event_call_for_papers/C omparativeWealth-DRAFT-IUSSP.pdf ???

Much appreciated

Hi everyone,

I'd like to generate the comparative wealth index for Peru and Bolivia DHS surveys. Are the alpha and beta coefficients available online? Does anyone know where? Otherwise, how could I get them?

Thanks,

Soraya
