Dear Listers,

I have data which provides me with information on wealth of each household. ID is the ID number for each household. Wealth is measured in US dollars (3 means 3 dollars). And I have weight for each household. My data look like this:

ID Wealth Weight
1 3 400
2 5 1000
3 1 350
4 0 200
5 0 300
6 9 450
7 11 250
8 20 100
9 2 500
10 4 450

I want to know the share of wealth held by the households who are in the top 10% of wealth distribution. Could you please tell me how to do it?
Thank you!

Yanran Guo
