Let me explain, what I want to do here. I have four variables of household id (ssuid), year, month and poverty. I have 28 months of data (May 2008 to August 2010). I want to see the distribution of poverty each month. Instead of doing this for each month manually, I want to do this by using stata's foreach and/or forvalue command.
Finally, I want to see what percent of household months were in poverty each month.

Thanks in advance!
