Center of population

• the point where the country would balance if….– it could be laid flat– all the people weighed the same

• At time of text’s publishing…..– 2.8 miles east of Edgar Springs, Missouri.– Why there?• Most of US population still lives on the east side of the

country.

5

demographer

• professionals who study population – Growth – Density– Other characteristics

• Most important factors of population are:– Fertility– Life expectancy– Net immigration levels

6

Fertility rate

• the number of births per 1000 women in the lifetime of the women.– Bureau of the Census estimates• Roughly 1.88 births/US woman.

7

Life expectancy

• average remaining lifespan of a people who reach a given age– Census Bureau estimates:

• 78.74, today• 82.1, 2050

• Other Nations– Britain 81.5– Japan 87– Mexico 77.2– Sierra Leone 38

Net immigration

• the change in population caused by people moving into or out of the country.– Census Bureau estimates:• 880,000• Based on

Dependency ratio

• the number of children and elderly/100 persons in the working-age.– 18-64

• Estimated by the Census Bureau– 1998 = 63.9%– 2020 = 67.5%– 2030 = 77.5%– 2040 = 78%

13

Section 4 :

• Real GDP per capita• dollar amount of all income made in a country,

in a year, per person.– Note: Counts non-workers• Retired• children

14

Growth triangle

• table that shows• Annual compound rates of growth between

selected periods of time.– 1929-1939 almost no growth– 2.9% growth, 1940-1970– 2.1, 1970-1980– 2.2, 1980-1990– Roughly 2.1, 2000-2010

force• High ratio encourages production– = economic growth

• Savings and investment stimulate growth– This is only possible in a few developed countries,

presently.

19

Labor productivity

• the amount of output produced per unit of labor input.– Increasing ratio = increasing productivity– Decreasing ratio = decreasing productivity

• The official measure of productivity

20

Assessments: section 3, Checking for Understanding

• 1 How does the rate of population growth affect economic growth?

• The size of the population directly affects the growth of one of the factors of production, labor

21

• 3 Describe how U.S. population is estimated• Census: every household receives a form to

complete• Other methods are used

22

• 4 List the three most important factors that determine future population growth.

• Fertility• Life expectancy• Net immigration

23

Assessments: Section 4, Checking for Understanding

• 1 Why is real GDP per capita considered the best measure of long-term economic growth?

• It adjusts for both inflation and population changes

24

• 3 Describe two measures of economic growth.• real GDP is the dollar amount of final output

for the whole economy• Real GDP per capita is the dollar amount of

real GDP produced per person

25

• 4 Explain why economic growth is important.• It raises the standard of living• Eases the burden of government• Helps solve domestic problems• Can boost the economies of foreign trade

partners

26

• 5 Identify the factors influencing economic growth.
