In a hypothetical city, which scenario implies the greatest built-in momentum for increasing population growth?

• The city has a large number of people aged 15 to 25

• The city has a large number of people aged 29 to 44

• The city has a large reproductive population

• The city has a large pre-reproductive population

What is the main reason that we have not suffered disastrous population crashes since the Industrial Revolution?

• We use fewer resources per person than we did 200 years ago.

• Despite the appearance of the numbers, there are actually fewer of us today.

• We now artificially create our natural resources.

• We have invented new ways to extract, process, and extend resources.

Which of the following equations represents population growth for an area?

• (births + deaths) - (emigration + immigration)

• (births + immigration) - (deaths + emigration)

• (births + immigration) + (deaths + emigration)

• (births + emigration) - (deaths + immigration)

What type of growth is expected in a population where the majority is in the post-reproductive age class?

• the population will neither grow nor decrease

• exponential growth

• linear growth

• the population will tend to decrease

As the average level of education and affluence increases, the average number of children per family will tend to

• increase.

• decrease.

Relatively high death rates are associated with what category of country?

• moderately-developed industrial countries

• wealthy, more developed countries

• poor, developing countries

• none - most countries have pretty similar death rates.

What is the main driving force behind the relatively high rates of natural increase in poorer, less developed countries?

• close tracking between birth and death rates

• significant decreases in death rates

• increases in the replacement-level fertility rate

• large increases in birth rates

Why is the replacement-level fertility rate slightly over 2 children per couple?

• The older generation is always dying off.

• That is as low as the birth rate can reasonably be expected to get.

• Some children die and some couples don't have children.

• We always need slightly more young people.

How has life expectancy changed over the last 100 years?

• increased slightly

• increased dramatically

• decreased slightly

• decreased dramatically

What shape age structure diagram is expected for a country with a rapidly growing population?

• inverted pyramid

• pyramid with a very broad base

• sides that are straight up and down
