o what is the price of gasoline and oil in this area?
o which landforms and waterways make up this region?

Which ethnic groups live in this community?

Explanation:

The demographers have their prime interest in the characteristics of the populations. This includes the ethnicity, race, education, types of work the population is engaged in, the migratory trends, birth rates, death rates etc. The ethnic composition of the population is one of the most interesting things about the demographers, so very often they focus on it, and rightly so, as the ethnic composition of the population can tell them a lot about the population.
