Could be. I hear a lot of activity on SSB and CW. Listening to 20m SSB area right now, it's pretty packed. IMO, two things have impacted "activity:" Lots more hams today live with antenna restrictions than ever before, so they have limited capabilities to generate very strong signals, which of course are the easiest ones to hear! They may also have local "noise" problems which limit their own ability to hear stuff, leading to less activity or possibly favoring the weak-signal digital modes where you don't have to listen to any noise, as the computer does that and does a good job of pulling signals out of the noise. Digital modes have become very popular! On a fairly "dead" band (for SSB/CW) if I tune to popular digital frequencies, and today especially FT8 watering holes, there's a lot going on -- I can tell that even without decoding any of it, just listen to the warblers and there's hundreds of them.
