These charts count sessions, not people. A session is a single visit, and one reader usually makes several over time, so these figures are larger than the size of the audience.

The totals aggregate eight QuantEcon lecture series. Sessions can be added across sites; user counts cannot, because a reader who visits three series would be counted three times, and Google Analytics offers no way to deduplicate them. That is why sessions are the figure reported here. Traffic from the Chinese, Persian and French translations is included under the corresponding English series.
