Hi, all.

Suppose I have the following data:

personal_number employment year
1 perm 1997
1 perm 1998
2 un-Emp 1997
2 self-emp 1998
3 perm 1997
3 self-emp 1998
4 self-emp 1997
4 perm 1998

Now, I want Stata to tell me how many people were self-employed in this data-set at SOME point in time. (3)

Next, I also want stata to list the whole employment history of anyone who has been self-employed at SOME point in time.

Could you please assist me?

Many thanks
andrey
