Google != Unacast, though.

There are plenty of background programs that are already embedded in various apps people use. Geotagged Twitter data has user ID’s attached to it, Google tracks most movements and of course records and stares all the voices that people use when using the microphone for voice to text etc. Facebook checkin’s etc. are also part of the mix of data sources. In the rural areas for these shorter periods of time they are looking at I am not sure how much sampling they get compared to more densely populated regions. Here are some articles on the topic: https://brianwebsterconsulting.wordpress.com/2018/07/12/where-will-the-5g-networks-be-built-carriers-are-not-the-only-ones-who-know/?fbclid=IwAR1OJd6xUliSCACfWjPwbfKTAWgZ_73Dqv_R6k3_MXz6ZVXbTJuw84FNm_Y https://www.newsweek.com/google-tracking-peoples-movements-their-communities-during-coronavirus-pandemic-1495915?fbclid=IwAR29LjfHTA68qM63HCWLX0vSycYIDlY9q3B4AnuOrVEJrBwB6tPQ--CW26g https://twitter.com/TectonixGEO/status/1242628347034767361?fbclid=IwAR30kyOEx1EcIvs4oXZ00Jd3uH5_euFVEgGlfSMLiBbnBBPMoOGMogXko4o https://www.nytimes.com/interactive/2020/04/02/us/coronavirus-social-distancing.html?smid=fb-share&fbclid=IwAR03RAWL4dJuZg6uXT1TroC_lcQ_xnxAaf5wKNpbKrZYyVeMFPS7R1pTg8c Location based data has been available for a while, most of it is supposed to be anonymized but you can still glean off a lot of useful information with the information. Some of these studies have been put together quite quickly so the methodology I see in questions. For instance I see no mention of the makeup of the workforce for any given regions. In my area a better than 50% of the population could easily be in the essential workforce category being that healthcare and the service industry are a majority of the employment. Those people are still going to work. Also if you look at the break down of things like their letter grades they give to regions the percentages from say a to C are very minor and I think that is just to cause more sensationalized results. When a 50% reduction in travel is noticed, I would not consider that a D grade in a rural area. They are just using numbers from pre and post stay at home orders to grade society.

Rural people drive farther to work or shop, that doesn’t mean they interact with more people. I may drive 50 miles to drop off radios for my tech to install but not interact with a single person. I saw one analysis that blamed it on Walmart for driving all the local stores out of business so people in some areas have to drive 20 miles to buy groceries or buy supplies. But again, what matters is probably how crowded that Walmart is and whether you practice distancing while shopping, not how far you drive to get there. I imagine anonymized cellphone geolocation data is available for this purpose, either from what celltowers you are near, or browser and app data.

They're using travel distance to determine who's good and who's bad. Is their data worth a shit? You could put 10k phones into 10k cars and drive them in circles all day and your reported metric would be through the roof, yet there was nearly zero additional risk because people were separated. How are they collecting this data? On whose behalf? With what permission? The only useful data would perhaps be in detecting the change in number of visible Bluetooth devices from January to now. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
