That's a statistic that is being extraordinarily obfuscated for a long time.
Latest of any sort I could find:
2018: The U.S. requested 160 and received 57 extradition requests for *violent* crimes, which represented 18.4% of all extradition requests made (in both directions). So there is a lot of room in that math, but that makes for 1,200 annual requests 2/3rd made by the U.S. and 1/3rd made to the U.S.

The last year I could find good, detailed statistics was 2002. The U.S. was running between 670 and 950 combined requests annually during the 90s. Figure we've had 20% population growth since the mid-90s, 950 + 20% is in line with the current level of extraditions (assuming both are "high" years and the 2018 figure of 1,200 wasn't a "low" year).
