Transit stations: How did the number of visitors change relative to before the pandemic?
What you should know about this indicator
- These datasets show how visits and length of stay at different places change compared to a baseline. Google calculates these changes using the same kind of aggregated and anonymized data used to show popular times for places in Google Maps.
- Changes for each day are compared to a baseline value for that day of the week:
- The baseline is the median value, for the corresponding day of the week, during the 5-week period Jan 3–Feb 6, 2020.
- The datasets show trends over several months with the most recent data representing approximately 2-3 days ago—this is how long it takes to produce the datasets.
- What data is included in the calculation depends on user settings, connectivity, and whether it meets our privacy threshold. When the data doesn't meet quality and privacy thresholds, you might see empty fields for certain places and dates.
- Google includes categories that are useful to social distancing efforts as well as access to essential services.
- Google calculates these insights based on data from users who have opted-in to Location History for their Google Account, so the data represents a sample of our users. As with all samples, this may or may not represent the exact behavior of a wider population.
