For the CCHS 2015-2016 PUMF—released in January— a new geographic classification variable (ALECLASS) based on open source data was added to the file. This variable is a categorical measure of the favourability of active living environment of each respondent based on their dissemination area and its intersection/dwelling density, as well as points of interest. Due to the addition of this variable, further data suppression was applied on the 2015-2016 PUMF to avoid disclosure risks. We are looking for any feedback you may have on the usefulness of the ALECLASS variable to help us determine if it should be added to the 2017-2018 PUMF. For the 2017-2018 PUMF there will be data on both physical activity and sedentary behaviors, so we see a potential usefulness, but would like to get a sense of how much the concept has been used so far.
