I get a lot of door knockers. I live in a low income area, demographic is mainly pensioners (I'm an exception). A quick google reveals there are over 100 rented properties on my road. Rentals exceed private residents homes. If I were canvassing a road, I would research my demographic. I would only bother with well off areas -people who have money, not pensioners or students. Why do sales canvassers bother with low-income areas? Doesn't make any good business sense to me in an industry that has a 96% rejection rate, (but obviously I'm no expert on sales).

Perhaps the well-to-do neighborhoods are saturated with salesmen who have to line up to wait their turn at someone's doorbell. All the poor people buy things, and not just things like automatic apple parers and cardboard closets and irregular children's clothes. They all seem to have TVs and PDAs they bought somewhere.

Two theories: 1. They're more interested in people's lack of intelligence than their income. 2. They're a mutated form of cockroach.

They are given the areas by their Managers and cover the whole of the City. You obviously do not see them knocking on doors in the rich areas.

Many of the poor are that way because they don't budget and spend easily. The rich know how to say no and mean it.

Rich people are usually tight, that is partly how they are rich. I heard 80% of millionaires use a second hand car.
