I’ve previously extracted a harmonized IHIS dataset covering the years 2000 - 2014. I recently decided to update the data to year 2015. However, I’ve lost almost all cases in the new dataset.
For example, I was interested in the “region of birth” variables. In my previous 2000-2014 extract, there were approx 6,000 people reporting Africa as their region of birth. However, the updated file (2000-2015) extract is reporting about 1200 people. Is the 2015 extract supposed to be merged with the previous ones to get the complete update ?
I went ahead and recreated the entire dataset/extract, selecting each variable again, but this did not help.
I would appreciate some pointers.
