I know OP didn't ask, but as someone in the US I get at least four calls per day on weekdays. Sometimes ten. Weekends are a little better. But I do have two numbers, the second number is also forwarded to my cell phone. So it's probably marginally higher because of that.
FWIW as an American I get maybe one a month. Have had the same number for a decade, never answered a single one. Also I never get spam text, I guess those are easy to filter.
