Merging Data

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

To merge new variables to a previous IPUMS-USA extract, you will want to merge your datasets together by the variables YEAR, DATANUM, SERIAL, and PERNUM. These variables will uniquely identify each individual from your two datasets.


Hope this helps.
