"Is there are a “Changes made to improve health” module in the CCHS 2007/2008 PUMF? It seems to only be available for 2000, by means of CANSIM table 105-0034."
"I have consulted the Canadian Community Health Survey (CCHS) 2007/2008 public use microdata file (PUMF) codebook (http://www.statcan.gc.ca/dli-ild/data-donnees/ftp/cchs-escc/cchs-escc2007-2008-eng.htm) and the file does seem to contain a "Theme module: Changes made to improve health - (F)" (see page 23 and onwards).
The CCHS 2007/2008 PUMF and related documentation files can be downloaded from our FTP site and website (http://www.statcan.gc.ca/dli-ild/data-donnees/ftp/cchs-escc/cchs-escc2007-2008-eng.htm).
I hope that this information is helpful. Please don't hesitate to let me know if you have any other questions."
