How to read the charts below: On the y-axis, 0 = baseline. This is the 'normal' amount of movement on a particular day of the week. Movement on Sundays is different from Wednesdays, so each day has its own normalised baseline. Google has calculated 'normal' for each day of the week, by finding each day's median during a five week period from 3 January to 6 February 2020. Therefore, keep in mind the seasonal and local characteristics of each state during that time of year (summer holidays, wet season).
