The principal city of this subdistrict is Netanya.

The subdistrict is situated in the Sharon plain, a section of Israel's coastal plain, from which it draws its name.

The subdistrict is mostly composed of what had been, during British-ruled Mandatory Palestine, the Tulkarm Subdistrict.

The rest of Mandatory Tulkarm Subdistrict east of the Green Line constitutes the current Tulkarm Governorate.
