Chapter 2 Appending and Merging

Appending and merging datasets are a crucial part of learning Stata or any other statistical package. Many times we are merging datasets by State FIPS, year, Zip Codes, Unit ID, County FIPS, etc. If we wanted to analyze local-level unemployment data to our analysis of county-level crime, then we will likely be using data from BLS and data from FBI or other local admin data.

Note: Working with multiple datasets: I do not have frames in Stata 14, but using frames is encouraged. Using the temp files workaround is a bit cumbersome (but it works). Using Stata frames will help work with those datasets simultaneously to get them ready to merge.
