Performing calculations with counts

I'm pretty new to SAS coding and I'm a bit lost right now. How would you perform calculations with counts. For example, I want to get the rate of falls by type (same level falls, different level falls, etc... I created a variable to differentiate for each type of fall (same_fall, diff_fall).

How would I add up the type of falls and then divide it by the population?

If you'd raised this in the Enterprise Guide forum my answer would have been slightly different, although the result would be the same.

It seems you want to perform a frequency analysis, you want a percentage for the frequency as a proportion of the population, and you want to perform it separately for each level of a variable that classifies a group to observe.

In Enterprise Guide there is a standard analysis task that will do everything for you. In Foundation SAS, your can simply run code similar to the following:

Proc Freq Data = MYLIB.MYDATA Missing;

This will produce frequencies for each level of classvar, and percentages for each class as well as the whole population.

Kind regards
