Population pyramid

Answer 12

An age structure diagram that is widest at the bottom and smallest at the top, typical of developing countries

Question 13

Developing countries

Answer 13

Countries with relatively low levels of industrialization and income

Question 14

Developed countries

Answer 14

Countries that have relatively high levels of industrialization and income

Question 15

Total fertility rate (TFR)

Answer 15

An estimate of the average number of children that each woman in a population will bear throughout her childbearing years.

Family planning

Answer 16

The regulation of the number or spacing of offspring through the use of birth control

Question 17

Replacement-level fertility

Answer 17

The number of children a couple must produce to replace themselves. Populations that are at replacement fertility are considered stable (not growing or shrinking)

Question 18

Doubling time

Answer 18

The number of years it takes a population to double

Question 19

Rule of 70

Answer 19

A method which dictates that by dividing the number 70 by the percentage population growth rate we can determine a population’s doubling time. Formula: doubling time (years) = 70 / growth rate(%)

Question 20

Theory of demographic transition

Answer 20

A theory that states that a country moves from high to lower birth and death rates as development occurs and that country moves from preindustrial to an industrialized economic system

Question 21

Birth rate

Answer 21

Formula: # of births per year / total population

Question 25

Global growth rte (no immigration or emigration)

Answer 25

Formula: r% = (CBR - CDR) / 10

Question 26

Natural Increase (no immigration or emigration)

Answer 26

Formula: CBR - CDR

Question 27

Finding future population from growth rate

Answer 27

Formula: (initial population) X (growth rate ) ^ years
