Page 2: Key Issue #2 : Where has the World’s population increased?

How do you measure population

change?

Page 3: Key Issue #2 : Where has the World’s population increased?

“You can measure population change through the Crude

Birth Rate, the Crude Death Rate, and the Natural

Increase Rate.”

Page 4: Key Issue #2 : Where has the World’s population increased?

The Crude Birth Rate (CBR) is the total number of live births a year for every

1,000 people alive in the society.

Page 5: Key Issue #2 : Where has the World’s population increased?

The Crude Death Rate (CDR) is the total number of deaths a year for every 1,000

people alive in the society.

Page 6: Key Issue #2 : Where has the World’s population increased?

The Natural Increase Rate (NIR) is the percentage by which a population grows

in a year.

Page 7: Key Issue #2 : Where has the World’s population increased?

NIR = (Crude birth rate − Crude death rate) / 10

Page 8: Key Issue #2 : Where has the World’s population increased?

The Total Fertility Rate(TFR) is the average number of children a woman

will have during her childbearing years.

Page 9: Key Issue #2 : Where has the World’s population increased?

The Infant Mortality Rate (IMR) is the annual number of deaths of infants under 1 year

compared with total live births.

Page 10: Key Issue #2 : Where has the World’s population increased?

Life Expectancy measures the average number of years a newborn can expect to

live at current morbidity levels.
