Scenario
In one area of your community the population consists largely of relatively recent immigrants to this country. Population density in the entire community has risen, and the planning department is under pressure from some members of the community to reduce density. In response to this pressure, a regulation to prevent subdividing existing residences into apartments is currently under consideration. You hold a community meeting to discuss the proposed regulation, and it is denounced as being discriminatory to the generally low-income, immigrant population who rent units in subdivided buildings. What might you do?
