Dear Statalisters,
I'm having trubles when I try to merge two datasets that have
different number of rows, because one of them has the individuals
labor history and the other only has some characteristics of them.
The first dataset ("first") looks like this:
id job_history inicial_year finish_year
1 waitress 1980 1985
1 self-empl. 1986 1991
1 unemployed 1992 2000
2 journalist 1985 1990
2 unemployed 1991 2005
.
.
6 economist 1990 1999
6 self-empl. 2000 2008
And the second ("second") one like this:
id sex age
1 F 20
2 M 75
.
.
6 F 60
So, when I try to merge those datasets using the "first" data set as
the master data, Stata tells me that "variable id does not uniquely
identify observations in the master data", and I don�t know how to
deal with this, so I'd appreciate if you could help me.
Thank you!
Leonor
