Using the on-line analysis tool, I would like to age-adjust the IHIS data while doing an analysis comparing the prevalence of back pain between 2004 and 2014 using the
multi-year data set. I notice that the following text had been posted by an MPC staff member in 2014:
“The age variable is not adjusted in the multi-year files. The multi-year files are created using the population adjustments for the median year, meaning that the weighted frequency of age should be an accurate representation of the population of the median year of the multi-year file.”
Since the muti-year data set is from 1997-2014, the median year is 2006. So this means that all years are age-adjusted to 2006 data?
Is it possible to use other weights than 2006? For instance folks usually age adjust using either the 2000 or 2010 Census data.
