Depends on how you define "in current use". Looking at the zone output files (the ones produced from the text files), one system has 580 zone files, another 587. In that first system, there are 436 unique files (the remainder being links, or files with the same content but a different name). The other system has 321 unique files, because it uses a modified zic that discards any data older than 2001.
So there are 436 distinct regions if you go back to the beginning of the zone data, and 321 if you consider only places that differed sometime in the 21st century. That's a surprisingly high number.
