How many door to door salesman do you encounter? Where do you live, if you can share?
I haven't seen one in decades, and even then it was usually some pamphlets or books to support a cause or the other.
On the phone (Italy), OTOH, I used to get daily scam call to buy "Amazon stocks" or change utility providers or install water filters. That seems to have massively faded out due to new regulations tho.
Probably a bit more than one per year. Mostly painters telling me I need to repaint.
Norway.
Jehovah's Witnesses, across Europe, still even nowadays. Some other minor religious sects targeting elderly, usually offering care or attention followed by vicious takeover of real estate.
Only because you have not been profiled as lone and vulnerable, doesn't mean the practice doesn't exist:)
Ireland, small town, average reputation housing estate: 1-2 per week. Primarily charities, ISPs and energy companies
