AP HUMAN GEO TUESDAY, SEPT. 20

Directions: Please come in, grab your FRQ journal on the front table and answer the following questions. 1.Calculate the doubling time for a country who’s growth rate is 7%, and 1.2% Write out the equation for each scenario. 2.What is the difference between crude birth rate and fertility rate? 3.What allows demographers to look at the sex ratio as well as the dependency ratio of country? What is the dependency ratio referring to? 4.A cohort is a term used to identify what? 5.A wealthier country will take on what type of shape? Poorer? Explain.

Data from: UN, World Population Prospects Developing Countries: Countries with high total fertility rates, high infant mortality rates and low life expectancies will have population pyramids with wide bases and narrow tops. HIGH POPULATION GROWTH

Data from: UN, World Population Prospects Wealthier Countries: Countries with lower total fertility rates and longer life expectancies have population pyramids shaped more uniformly throughout. LOW POPULATION GROWTH

POPULATION PYRAMIDS IN TRANSITION

LET’S LOOK AT THE USA

WHICH REPRESENTS A COLLEGE TOWN? ABC

WHICH REPRESENTS A MILITARY BASE? A BC

WHICH REPRESENTS A RETIREMENT COMMUNITY? ABC

WHICH REPRESENTS A TYPICAL AMERICAN CITY? A B C

WHICH REPRESENTS A NATIVE AMERICAN REZ? ABC

POPULATION PYRAMIDS In looking at your population pyramid, DISCUSS: 1.Developed or developing country? 2.High or low death rate? 3.High or low life expectancy? 4.High or low dependency ratio? 5.Rapidly growing, moderately growing, low growth, or negative growth? 6.Overall what is happening in this country? What strains or pressures (if any) will the government or country face in future years?

Tuesday, Sept. 20 DEMOGRAPHIC TRANSITION MODEL

DEFINED: explains the transition from high birth and death rates to low birth and death rates as a country develops from a pre-industrial to an post-industrial economic system. DEMOGRAPHIC TRANSITION MODEL

Stage 1: Low Population Growth Stage 2: High Population Growth Stage 3: Moderate Population Growth Stage 4: Low Population Growth Stage 5: Declining Population Growth

STAGE 2: HIGH GROWTH Cape Verde Entered stage 2 of the demographic transition in about 1950, is experiencing rapid population growth. Its population history reflects the impacts of famines and out-migration.

STAGE 3: MODERATE GROWTH Chile Entered stage 2 of the demographic transition in the 1930s, and it entered stage 3 in the 1960s.

STAGE 4: LOW GROWTH Denmark Been in stage 4 of the demographic transition since the 1970s, with little population growth since then. Its population pyramid shows increasing numbers of elderly and few children.

STAGE 5: (-) GROWTH JAPAN CDR > CBR because of an aging population. NIR is less than Zero. Much of Europe is entering this stage.

POP PYRAMIDS & DTM

The model failed to consider, or to predict, several factors and events: 1.Birth rates in MDCs have fallen below death rates causing a population decline. 2.The model assumes that all countries pass through the same 4 stages. Not necessarily true for all of the world’s economies. It is becoming likely that Africa will not become industrialized. 3.The model assumes that the fall in the death rate in Stage 2 happened because of Industrialization. In many countries, the decline in death rate in Stage 3 has been less rapid than the model suggests due to religious/political opposition whereas the fall was more rapid in China following the ‘One Child’ policy. 4.Countries that grew as a consequence of emigration from Europe did not pass through the early stages of the model. IS THE MODEL UNIVERSALLY APPLICABLE?

Demographic Transition Model Theory: Fictional Families Activity Create a fictional family for stage 1, 2, 3, 4, and 5? to illustrate the demographic changes that occur over time. Requirements Checklist:  Name your fictional family members for each separate stage!  Illustrate your fictional families for each stage  Where do they live?  Explain their lifestyle,  environment,  conditions,  resources, etc. Key terms must be used in your explanations (i.e. IMR, TFR, etc).  Also explain what is happening amongst the total population around them. What changes are happening and why?

DTM FINISH Feb. 16

Tuesday, Feb. 16 Directions: Complete the chart below, labeling each axis and identifying the birth rate, death rate, total population, natural increase and stages of the DTM. NO NOTES!
