st: re. computing RR thru proportions

Dear all
I have got people with MS per month over one year (i.e., the A) and used
UK Births for each month, as my control group, again over 12 months, so
I have got the C in a typical 2x2 table. These are two time-series,
each of 12 months.
I need to take the UK population proportion for January against PwMS
proportion for January and so on in order to compute risk ratios. When I
do this and enter the information in STATA, the results look
unreasonable.
Using proportions seem to be causing a problem.
Would you please be kind enough to help me how best I would resolve this
issue.
Thanks very much
Panos
