Adding data from excel to existing SAS dataset

[mayasak]

Hi,

I have a SAS data set which has data for "estimated population count" for 33 counties "Fipscode:county fipscode, 2-digit numeric"variable, years 1990-2016. I have to add a variable named ALAND10 (from excel) which has a land area for each of the fipscode county variable in SAS (33 counties). 

Later I need to calculate population density from the land area and population estimates. I've attached a SAS data and excel clip.

Thanks

So what is the question?

Read the new data into a SAS dataset and then merge the two datasets by the FIPS code.
