HARMONIZED KLOSA CREATION CODE

The Gateway Harmonized KLoSA version F dataset is created using data from KLOSA Wave 1 - 9, available as of June 2025.

*Gateway Harmonized KLoSA F contains 8,819 variables and will require Stata/SE or Stata/MP.

To run the Harmonized KLoSA Creation Code in Stata:

From KEIS, download the combined KLoSA 1-9th wave (Stata) file, download the combined KLoSA 1-7th wave imputation file, and download the individual Stata exit data files for waves 2-9.
Unzip the KLoSA 1-9th wave (Stata) file and the KLoSA 1-7th wave imputation file, and place all files in the same folder as the other KLoSA data files.
Edit line 13 of the Stata Creation Code to list the folder location of all KLoSA data for all waves and edit line 14 to list the folder location where you would like to save the Harmonized KLoSA dataset.

If you prefer to work with the Harmonized KLoSA dataset in a statistical package other than Stata, you can convert the Harmonized KLoSA Stata dataset using a program such as Stat/Transfer. If you do not have access to Stat/Transfer, you may be able to read the .dta dataset into your stat package using an "import" or "get" function. When reading a .dta dataset into another package, it is best to first save the dataset in a Stata version 12 format using the command saveold.
