Re: Convenience Sample ?

If you are trying to identify a population representing a rare event,
say here in the U.S. and let's say for example you, call each State's
capital office of economic development and ask, in your State, in
which jurisdictions\counties, might I find manufacturing businesses 2
years old, owned by minority folk and whose revenues doubled from
year 1 to year 2.

I've made up the following, just to illustrate my question.

My guess is this population would be pretty small. So I might be
provided a list of counties, but the office doesn't have a specific
tracking process in place, it's more based on the anecdotal
experience
of the person I am talking with and their knowledge of the State's
business community, so they name a number of jurisdictions\counties
in
their State, so I call these counties' chamber's of commerce to
assist
in ID'ing the population. In the end it is highly unlikely I'll
capture the population, so this is my question, 1) do I technically
end up with a sample (non-probability of course) and 2) could I
consider it a convenience sample?

Any input would be appreciated on this, thanks.

My view is that it is a convenience sample because it is based on the
haphazard asessment of several different individuals. For the
questions you posed in your example, you would tend to get the most
visible such businesses. Other successful operations, perhaps
employing fewer people, having less advertising, a lower community
profile, or manufacturing an obscure product would tend to be left out
of your sample.
