Well, i moved to the US only a few years ago, so i might be a good case study.
In my first year over here, i didn’t have any US credit cards, i had a single US bank account, i didn’t purchase anything online, and the only people with my address were my bank and my utility companies (telephone, gas, electric).
What i did do, however, was subscribe to about eight different magazines, mainly liberal and left-wing. I took out subscriotions to The Nation, The Progressive, Harper’s, Atlantic Monthly, Z Magazine, Columbia Journalism Review, National Geographic, and Dollars and Sense.
Within about six months, i was receiving a whole bunch of unsolicited mail, including quite a few envelopes containing address labels. Unsurprisingly, given my subscriptions, most of the mail was from progressive, liberal, or leftist organizations. I think that Medecins Sans Frontiers sent me more address labels than anyone else, although a couple of environmentalist groups (oh, the irony) came close.
I can’t really use the address labels, though, because they don’t have my home address on them. I’m a grad student, and in all my magazine subscriptions, i used my university mailbox address, because my departmental mailbox is a lot larger than the apartment mailbox i had back then, and it prevents the magazines from getting crunched up or stolen. As it turns out, it also prevents my home mailbox from being crammed with unsolicited mail.
