1 The six main population clusters are..

2 East Asia, South Asia, Southeast Asia, Nigeria, Europe, Northeast United States.

3 What is population distribution?

4 The way people are spread out across the earth’s surface

5 What is arable land?

6 Land used for agriculture

7 What is agricultural density?

8 The ratio of the number of farmers to the amount of arable land

9 What us arithmetic density?

10 The number of people per unit of land

11 Nearly 70% of the worlds population lives within ___ kilometers of a coast

12 400

13 What is Physiological density?

14 The number of people per unit of arable land

15 What is a population pyramid?

16 A bar graph that shows the composition (primarily gender and age) of a population

17 Describe the stages of a demographic transition model

18 a stage one - narrowing of the wide base, showing a lot of people being born and dying at a young age. (THERE ARE NO COUNTRIES IN STAGE ONE) Stage two (Afghanistan) - wide base, rapid growth (early expanding) Stage three (Saudi Arabia) - smaller base as growth slows and a high life expectancy (late expanding) Stage four (U.S.A) – narrow base because of very slow growth and aging. (low fluctuating) Stage five (Japan) – top heavy pyramid, due to few children and lots of elderly

19 What us the Demographic Transition Model?

20 A theoretical model used to estimate a country’s population projection. Based on Crude Birth Rate and Death Rate

21 What are the stages in a DTM?

22 Stage one- high stationary Stage two – early expanding Stage three – late expanding Stage four – low stationary Stage five - declining

23 What is crude birth rate?

24 Total number of live births in a year for every 1,000 people living in the region

25 Doubling time is..

26 Amount of time it takes for the region to double in population; assuming that is a constant rate.

27 What is Net Migration?

28 The difference between immigrants and emigrants

29 What is Replacement Rate?

30 A TFR of 2.1; rate so that women have enough babies for the next generation

31 Who is Thomas Malthus? What was his theory?

32 He was an English economist who concluded population would exceed carrying capacity; while food supply increases arithmetically (1,2,3,4,etc.) population increases geometrically (1,2,4,8,etc.).

33 Who is Ester Boserup? What was her theory?

34 Opposed to Malthusian theory; believed that with more people to provide labor, food production would increase

35 What was the Cornucopian theory?

36 Human population growth will result new technologies that will make it possible to increase food supply and the carrying capacity

37 A Pro-Natalist is also known as

38 Expansive

39 An Anti-Natalist is also known as

40 Restrictive

41 Women are less educated worldwide in..

42 LDCs

43 Contrast fertility on MDCs and LDCs

44 MDCs have lower FRs due to more wealth, education, urbanization, etc. LDCs have higher FRs due to the opposite: less wealth, education, urbanization, etc.

45 What is a push factor?

46 A factor that causes you to move out of a country

47 What is a pull factor?

48 A factor that causes you to move to a country

49 Examples of push and pull factors

50 Push: poverty, lack of jobs, natural disasters Pull: religious freedom, job opportunities, higher standard of life

51 Population/migration question What are some of the reasons why population is clustered in places like East Asia, Nigeria, Europe, & Northeast United states?

52 Population/migration answer The place might have factors such as good climate where moderate rainfalls are comon to help support agriculture, landforms with lowland areas or bodies of water, certain ethnic groups that want to live near each other, places with good infrastructure and a strong government. Answer is found on page 7 on the big ideas packet!

53 Question 1 Why is it that women are usually less educated worldwide?

54 Answer 1 Education and fertility have an inverse relationship. More education= less fertility, vise versa

55 Question 2 What are some push and pulls factors of migration?

56 Answer 2 Push- unfavorable conditions that encourage people to emigrate. Ex. Lack of jobs, poverty and natural disasters Pull- favorable conditions that encourage people to immigrate. Ex. Job opportunities, higher standard of life, religious freedom, etc.
