A thematic map shaded to show how many people live per square mile is displaying—
- a.the elevation of the land
- b.birth and death rates
- c.population density✓
- d.total population
Density is a ratio of people to area, which is exactly what people per square mile expresses, and shading is the usual way to show it. Total population is a count that ignores area, better shown by graduated symbols. Birth and death rates describe change over time rather than crowding. And elevation belongs on a topographic or relief map.
