How much transit activity will there be in the San Francisco Bay Area in the last week of September?

Cross-posted on Metaculus: Pandemics.


Governments across the world are now reopening businesses and loosening lockdown policies put in place to mitigate the spread of COVID-19. In the United States, all 50 states have announced plans for various levels of reopening. But experts and pundits disagree on how sustainable such reopenings are, and in what shape the economy will react or recover.

Appleā€™s Mobility Trends dataset shares changes in the number of requests for Apple Maps directions on a daily basis, indexed to 13-01-2020. The data is updated daily and identifies trends for driving, walking, and transit for various cities, countries and regions across the world.


What will the Apple Mobility Trends report as the mean level of transit activity in San Francisco - Bay Area for the week of 20-09-20 through 26-09-20 (inclusive)?


  • Mean of the values reported by the dataset, also linked above, for the dates 20-09-20 through 26-09-20 (inclusive).
  • For San Francisco - Bay Area, not San Francisco county.
  • Example: For the San Francisco Bay Area during the week of 17-05-2020 to 23-05-2020, the values for transit activity were

    • 17-05: 20.40
    • 18-05: 24.10
    • 19-05: 19.87
    • 20-05: 23.30
    • 21-05: 20.82
    • 22:05: 24.93
    • 23-05: 20.00
  • So the mean over this time would be 21.92

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
