Subject: st: how to summarize while accounting for duplicate values

I am trying to summarize a dataset in Stata 10.1 on individuals'  
reproductive success throughout their life. The database is set up  
with each individual having an annual entry with multiple variables.  
Some variables' values change annually (e.g. # offspring born), while  
other variables have duplicated values for each year as they do not  
change over the course of their life (e.g. age of first reproduction,  
lifespan). How do I get Stata to provide summary statistics for chosen  
variables of interest in the population that accounts for individuals'  
duplicated values for some variables that don't change annually?

Thanks in advance for your help.

Dan
