note: some reports indicate that the 24 departments and 1 constitutional province are now being referred to as regions; Peru is implementing a decentralization program whereby these 25 administrative divisions will begin to exercise greater governmental authority over their territories; in November 2002, voters chose their new regional presidents and other regional leaders; the authority that the regional government will exercise has not yet been clearly defined, but it will be devolved to the regions over the course of several years
Rewritten: too little of the 2002 text remains to mark the changes.
