Population Density Calculations

The video tutorial explains how to calculate the population density of the United States in 2010. It begins by introducing the population and land area data, then explains the concept of population density. The tutorial guides viewers through the calculation process, emphasizing the importance of rounding to the nearest tenth and verifying results using a calculator.

What was the population of the United States in 2010 according to the study?

• 350,000,000

• 300,000,000

• 250,000,000

• 308,745,538

What was the approximate land area of the United States in 2010?

• 3,531,905 square miles

• 3,000,000 square miles

• 4,000,000 square miles

• 2,500,000 square miles

What is the significance of the year 2010 in the study?

• It is the year the study was published

• It is the year the population peaked

• It is the year the land area changed

• It is the year the data was collected

What does population density measure?

• People per square mile

• Total population

• Land area in square miles

• Number of cities

How is population density calculated?

• Population plus land area

• Population multiplied by land area

• Land area divided by population

• Population divided by land area

What is the purpose of calculating population density?

• To find the number of cities

• To measure the land area

• To determine the total population

• To understand how crowded an area is

What is the population density of the United States in 2010 rounded to the nearest tenth?

• 100.0

• 85.0

• 87.4

• 90.0

What is the first step in calculating population density?

• Subtract the land area from the population

• Divide the population by the land area

• Multiply the population by the land area

• Add the population to the land area

Why is it important to round the population density to the nearest tenth?

• To ensure precision

• To make the number larger

• To simplify the calculation

• To match the population

What is the population density of the United States in 2010 before rounding?

• 87.416

• 90.000

• 85.000

• 100.000
