Step 2: The variable hlf0241_h is replaced with -2 for the years 2016 to 2021, if hlf0241_v4 is less than 0 and hlf0241_v5 is less than 0.
Step 3: The variable hlf0241_h is replaced by the variable hlf0241_v4 for the year 2016, if hlf0241_v4 is greater than 0.
Step 4: The variable hlf0241_v3 is recoded (1=2) for the year 2014 and subsequently integrated into the harmonized variable hlf0241_h.
Step 5: The variable hlf0241_h is replaced by the variable hlf0241_v2 for the year 2015.
Step 6: The variable hlf0241_v1 is recoded (1=1) (-2=2) for the years 2000, 2002, 2004, 2006, 2008, 2010, 2011, 2012 and 2013 and subsequently integrated into the harmonized variable hlf0241_h.
