How does one discuss microeconomically; discrimination, in ones city?

Answer 1

1 The census has PUMS files that has survey information on households. The data include income education race age Hispanic etc. If there is wide spread discrimination, it should show in the analysis of the data.
2 Check for the distribution of city services school expenditures trash pickups road repair (census has records on racial composition of neighborhoods)

Answer 2

Not easy, since you should stick to facts. Anecdotal evidence is usually *too* micro to generalize from.

Your province or state likely has a Human Rights Commission (or some such name); it'll be in your phone book. That group keeps statistics on types of discrimination, such as racial, sexual, occupational and so on. They may even break their data down to particular ethnic communities and to the city level (though that's less likely).

Besides that human rts group, phone your city and university libraries' reference desks for other local sources.
