Population Growth Concepts and Calculations

The video tutorial covers various methods of measuring population growth, including raw growth by difference, proportionate growth change, and different growth functions like exponential and logistic. It discusses historical perspectives, such as Malthus's geometric growth theory, and explains growth by components, which includes natural increase and net migration. The tutorial uses the United States as an example to illustrate these concepts.

What is the method called when you calculate population growth by subtracting an earlier population count from a later one?

• Logistic growth

• Exponential growth

• Raw growth by difference

• Proportionate growth change

How is proportionate growth change calculated?

• By adding the birth rate to the death rate

• By multiplying the growth rate by the population

• By dividing the growth rate by the population

• By subtracting the earlier population from the later population

Which growth function initially described human population growth before it became more logistic?

• Quadratic function

• Linear function

• Geometric function

• Exponential function

What did Malthus suggest about population growth?

• It grows at a linear pace

• It grows at a quadratic pace

• It grows at a geometric pace

• It grows at a logistic pace

During which period did population growth occur at an exponential pace according to the video?

• The Information Age

• The Middle Ages

• The Industrial Revolution

• The Renaissance

What are the components of population growth by components?

• Birth rate and death rate

• Carrying capacity and birth rate

• Natural increase and net migration

• In-migration and out-migration

How is natural increase calculated in population growth?

• Population minus deaths

• In-migration minus out-migration

• Births minus deaths

• Births plus deaths

What does net migration consist of?

• Growth rate minus natural increase

• Population minus natural increase

• In-migration minus out-migration

• Births minus deaths
