Per the most recent (March 2022) Orbital Debris Quarterly News issued by NASA, the International Space Station has conducted 30 orbital debris avoidance maneuvers since 1999. That's a bit over one per year, on average.
The ISS is certainly going to be an outlier with regard to the frequency at which it performs collision avoidance maneuvers, for several reasons:
- The ISS has people on board.
- The ISS is by far the largest object in space.
- The ISS is by far the most expensive object in space.
- The ISS is regularly resupplied with propellant.
The first three of the above reasons means NASA and Roscosmos have to be very aggressive regarding avoiding potential collisions with debris. The final reason means that NASA and Roscosmos can afford to be very aggressive with regard to avoiding potential collisions. While other spacecraft are expensive, none come close to the value of the ISS. Most spacecraft are not refuelable, so most space operators have to tolerate more risk than the ISS. I suspect that for most spacecraft in low Earth orbit that it's well under one collision avoidance maneuver per year.
