Google charts how the pandemic has changed New Brunswickers' routines

Google released charts that appear to show how New Brunswickers are changing their routines as a result of the pandemic. Google says the information is meant to help governments gauge the effectiveness of measures to control the spread of the novel coronavirus.

Google released charts that appear to show how the routines of New Brunswickers have changed as a result of the pandemic.

The company published charts Friday comparing recent traffic at locations, such as grocery stores, to traffic during the month of January.

It shows growing traffic to grocery stores as the first cases were confirmed in the province and plunging use of transit stations in the weeks that followed.

Google states in a blog post that the information is meant to help governments gauge the effectiveness of measures to control the spread of the novel coronavirus, which hasradically altered routines and whatcan stay open.

The information is collected from users of Google applications who have consented to the company collecting their data.

David Fraser, a Halifax-based privacy lawyer with McInnes Cooper, said it's not the sort of information he's concerned about.

Fraser, who has represented Google in the past, said from a privacy perspective he is comfortable with how the data has been collected and presented.

He said looking at the graphs for Nova Scotia, where he lives, you wouldn't be able to tell which "microscopic data point" is him.

"If this is information that's useful to public health authorities in order to determine whether or not people are following the guidance related to working from home and self-isolation and all those sorts of things we've been hearing so much about, then hopefully it's useful in that regard," Fraser said.

CBC News has asked the New Brunswick government if it is aware of the information and whether it is useful, but no one has responded yet.

How it works

The information released Friday outlines movement trends across 131 countries or regions, providing an overall percentage change for six broad categories of locations like retail and recreation.

The company states the aggregated, anonymized data was collected from people using Google products who turned on the location history setting, one that's off by default.

The data compares behaviourbetween Feb. 16 and March 29 to the same days of the week between Jan. 3 and Feb. 6.

The information collected is typically used bythe company in Google Mapsto show things like congested roadways or popular times at businesses.

Fraser said it's a setting he has turned on, which has proven to be useful for trying to remember details such as arestaurant he visited years ago.

He noted that if he were to become ill with the coronavirus, he could use the location history function to help public health officials trackwhere he has been and who he may have been in contact with.

It's not clear how many users the New Brunswick trends are based on, but the company says it leaves out regions if it doesn't have "statistically significant levels of data."

Traffic at places considered workplaces plunged after the weekend of March 16. (Google)

Movement in workplaces dropped 35 per cent compared to the baseline, with the biggest dip around Sunday, March 16. By that point, the province had approximately sixconfirmed or presumptive-positive cases of COVID-19.

Fraser noted the company doesn't differentiate between essential and non-essential workplaces.

Retail and recreation locations saw one of the largest drops starting the weekend of March 16. (Google)

Retail and recreation plunged 42 per cent compared to the baseline time period. The category includesrestaurants, cafes, shopping centres, theme parks, museums, librariesand movie theaters.

The chart shows peaks and troughs until the week of March 16, at which point the trend line plunges.

The province declared a state of emergency March 19, ordering many businesses in thatcategoryto close or change their operations to meet physical distancing requirements.

Grocery and pharmacy locations saw an increase in the days following the announcement about the province's first cases before also dropping. (Google)

Grocery and pharmacy locations dropped 20 per cent overall. However, the chart does show a spike in activity at these locations in early March as the province's first cases were announced.

Photos of empty store shelves were common and government officials urged people not to panic-buy goods. The trend line dips around the week of March 18.

Use of parks in New Brunswick appears to spike on weekends. (Google)

Large spikes are recorded in weekend use of parks, which is a category that includes national parks, public beaches, marinas, dog parks, plazasand public gardens. Overall, the use of parks was up 101 per cent compared to the baseline.

There have at times been conflicting messages about the use of parks. National and provincial parks have closed while some municipal facilities in the province are also closed.

A large spike was recorded the weekend of March 29.

Dr. Jennifer Russell, the province's chief medical officer of health, suggested in a Saturday, March 28 news release that with good weather "people enjoy the outdoors while practising physical distancing" that weekend.

Over the following days, Premier Blaine Higgs was asked multiple times by reporters about parks as photos of packed parking lots were shared online.

On Tuesday, he said he expected municipalities to follow the province's lead and close them. By Wednesday, his stance had shifted. Higgs said parkscan remain open if physical distancing is enforced.

A slight increase in the number of people at 'residential' locations has occurred in recent weeks. (Google)

The residential category has shown a modest increase of eight per cent.

Google noted that the data included depends on user settings, connectivity, and whether it meets our privacy threshold. It noted that when the threshold isn't met for example, if someone isn't "busy enough" to ensure anonymity, it doesn't show a change for that day.

Transit stations record the largest drop in use of any of the six categories of locations. (Google)

Transit stations, which includesbusand train stations, recorded the largest decline, at 47 per cent, compared to the baseline time period. That drop began around March 16.

VIA Rail halted its passenger train service throughthe province. The province's major cities have made changes to transit service in recent weeks.

For example, Codiac Transpo in the Moncton region, has reduced transit hours, limited buses to six passengers and cut Sunday service.
