Commuter flows in the CSA are counted both ways. It's more than 15% both ways (from Boston to Providence + from Providence to Boston). In the FUA the commuter flows are counted only from the periphery to the central area.

It's people commuting into the central core of Paris, which is City of Paris plus a certain number of suburbs of Paris (but not the entire urban area of Paris). For example Goussainville and Les Mureaux are part of the urban area of Paris, but they are not part of the core area of Paris used to define the FUA of Paris (but they are part of the FUA of Paris because more than 15% of their residents in employment commute to the core area of Paris).
The FUA of Paris is made up of the core area of Paris, plus some other core areas that could have been their own FUAs but which are included in the FUA of Paris because more than 15% of their residents commute to the core area of Paris (such as Meaux, Melun, Mantes-la-Jolie, Creil), plus some municipalities that are outside of core areas and more than 15% of whose residents commute to the core area of Paris (such as Goussainville and Les Mureaux, or exurbs like Marolles-en-Hurepoix, Crépy-en-Valois, etc).
The FUA of Paris (within its 2020 borders) had 11,729,644 inhabitants in 1999, and it reached 13,125,142 inhabitants in 2020.
