Hello,
I have a previously downloaded data set for females in the year 2014 from IPUMS-USA. I want to download additional variables to add to this data set. However, I am using SPSS and I am concerned about how to merge the two data sets so that the additional variables are still applicable to the women from my original data set.
Do I need to start over and download all of the variables at once to ensure that the observations correctly match each woman?
Thank you!!
Sonja
