Question 1A district has 156,000 residents across 480 km² of land. Find its arithmetic density in people/km², rounded to one decimal place.

Enter a number in people/km².

Answers within 0.05 people/km² of the expected value are accepted.

Question 2A region has 840,000 residents and 2,400 km² of arable land. Find its physiological density in people per km² of arable land, rounded to one decimal place.

Enter a number in people/km² of arable land.

Answers within 0.05 people/km² of arable land of the expected value are accepted.

Question 3Out of 180,000 regional residents, 63,000 live in the eastern zone. Find the eastern zone’s share of residents in %, rounded to one decimal place.

Enter a number in %.

Answers within 0.05 % of the expected value are accepted.

Question 4Two districts have the same average density, but one has a compact town and the other scattered hamlets. What differs?

The arithmetic density by definitionThe total area implied by the settlement patternThe required equality of their transport networksThe spatial arrangement of their residents

Question 5A population dot is plotted within a census zone. What should a reader check before treating it as a household location?

The source-area method and the population represented by a symbolA match between the zone’s average and a neighboring zoneThe nearest road as confirmation of a dot’s exact placementThe resemblance of the dot cluster to a town’s street layout

Question 6Changing density-class boundaries makes the same choropleth map look sharply divided. What changed?

The number of residents living in each districtThe ranges assigned to the colors rather than the underlying ratesThe dates on which the census counted householdsThe locations of the district boundaries on the ground

Question 7Tall office towers dominate a district that has few residents at night. Which measure avoids confusing buildings with people?

The population implied by the total office floor areaThe resident count linked to the area being measuredThe skyline’s visual prominence in a photographThe height of the tallest tower divided by street length

Question 8The town’s reported density falls after its boundary expands into sparsely inhabited land. What must be checked before claiming residents left?

A lower rate as confirmation that residents have departedThe map color assigned to the newly incorporated landWhich people and land entered the new reporting unitThe appearance of the former boundary in archived maps

Question 9Emergency planners combine a flood map with population data. Which statement correctly guides evacuation planning?

District boundaries define how far floodwater will spreadThe most populous district has the greatest exposure to the floodThe density ranking gives the order in which districts will finish evacuatingTravel routes and residents’ mobility affect how quickly people reach safety

Question 10A crowded region imports resource-intensive goods. Which account correctly describes its environmental pressure?

Residents’ purchases use resources both nearby and in producing regionsThe height of apartment buildings determines households’ water demandThe land within its borders contains the footprint of its purchasesDoubling resident density doubles total consumption of natural resources
