Where the report counts βpassengersβ it means passenger movements. Every time a passenger arrives or departs by air constitutes a passenger movement. A transit passenger makes two movements, one when arriving and one when departing. In your example you would be noted as one arriving international passenger and one departing domestic passenger.
Edit:
I think it is evident from data in the report that numbers are calculated as above. Let us look at commercial passenger traffic data for JFK from 2017.
The reported number of passengers is domestic inbound + domestic outbound + international inbound + international outbound. 13,534,099 + 13,426,982 + 16,400,104 + 16,031,315 = 59,392,500. The number of passengers is clearly just the sum of arriving passengers plus departing passengers. [page 43]
When comparing JFK with other airports in the world, the same total is used, 59,392,500 passengers, putting JFK at 22nd place, well behind Dubai at 3rd, which is known for being completely dominated by transfer passengers. Transfer passengers must be included in this number, which in turn is arrivals plus departures. [page 28]
Also when listing airlines by passenger numbers, which would hardly exclude transfer passengers, the grand total is the same. [page 41]
