The 2007 online data use to include complementary and alternative medicine approaches. Why did you take them off?
The online data analysis tool can only support a limited number of variables. As the IHIS project has expanded this variable limit was exceeded and the IHIS team had to be selective about which variables can be accessed via the online data analysis tool. They primarily targeted variables that were download frequently and/or were available for most years. Unfortunately, this meant removing a number of variables that had been previously available. I have passed along you interest in these variables to the IHIS team, as we are always interested in input from researchers.
