It is funny Changing City seems to be doing a regular Daily Hive trick and not sourcing his info from yesterday's BIV article on WFH. Then Feathered Friend does link another BIV story about Marshall leaving.
"Downtown Van, formerly the Downtown Vancouver Business Improvement Association, has also used cellphone data to measure downtown activity. President and CEO Nolan Marshall III said this type of data can have significant limitations when comparing American and Canadian cities, owing to the latter’s stricter privacy laws.
“My experience talking to colleagues, my experience visiting other places, just runs completely counter to where I think that report ultimately had Vancouver ranked,” he told BIV in August.
Marshall said problems also arise depending on how one defines a visitor when using cellphone data to judge how active an area is.
Vancouver’s downtown peninsula is one of the most densely populated areas in Canada and the U.S.
“If you draw your data collection map across the entire downtown, you're not identifying people who live within the area as a visitor,” Marshall said, “which is why we only do our cellphone data collection around our retail districts, and specifically so we can track how many people are going into those retail districts since they don't have as many residents as the rest of downtown.”
