When I say TF, you say R!
High TFRs are usually associated with this pre-industrial characteristic.
What is infant mortality?
This stage of demographic transition is characterized by high infant mortality.
What is pre-industrial?
This formula is used to calculate the time it takes for a population to double.
What is Rule of 70?
This term describes the deforestation and subsequent land use associated with housing developments around urban areas.
What is suburban sprawl?
This is the number of different pairs of glasses Mr. McKeon typically wears to school.
What is 2?
Overall, worldwide TFRs are...
What is decreasing?
Life expectancy is low when...
What is infant mortality is high?
A population has a growth rate of 2% per year. This is the number of years it will take to double in size.
What is 35 years?
This is the first step to slowing overpopulation and human population growth.
What is economic development?
This is the age of Lily Harper McKeon (Mr. McKeon's older daughter).
What is 4.5 years old?
This is the impact of people marrying later.
What is childbearing is delayed / fewer children?
This stage in the demographic transition is characterized by slow population growth, where the birth rate approaches the death rate.
What is industrial?
A population that doubles in size after about 350 years would have a growth rate of...
350 = 70/.2
What is 0.2%?
These are some negative impacts related to overpopulation (list 2).
What is deforestation for housing / farming, burning fossil fuels for intensive energy consumption, depleting fish stocks through overfishing, pollution - such as carbon emissions that cause climate change or agricultural runoff that causes eutrophication, etc.?
This is Mr. Young's shoe size.
What is size 11?
A country experiencing access to vaccines and immunizations for the first time would be in this demographic transition stage.
What is transitional?
A country like Kenya would have higher TFRs becuase... (list 3)
What are higher infant mortality, less developed / access to contraceptives, less family planning, women have less education / career opportunity, more children can support the family, women have children earlier, fertility is celebrated culturally, etc.?
A population of 2,000,000 that has 20,000 births per year would be experiencing this crude birth rate (CBR).
CBR = (births / population) x 1,000 to make crude
20,000 / 2,000,000 = 0.01
0.01 x 1,000 = 10
CBR = 10
An age structure diagram with a narrow base would be experiencing...
What is zero or negative growth?
This is Mr. Dzinney's preferred sport.
What is rock climbing?
These are the reasons TFRs are decreasing (list 5).
What are increased education for women, increased career opportunity for women, access to contraceptives, family planning, improved survivorship of children, and cultural shifts.
Decreased death rate and rapid population growth are correlated to these factors (list 4).
What are improved sanitation, healthcare, technology, increased food supply, and disease control?
This is the growth rate (r) for a population with 10 CBR, 5 CDR, and 0.5 net migration.
r = (CBR - CDR + net migration) / 10
r = (10-5) + 0.5
r = 5.5 / 10
r = 0.55%
This is the world population as of June 2025 (answer with 2 decimal places).
What is 8.21 billion?
This is Mr. Broyles height in meters.
1 foot = 0.3 meters
6.1 feet = 1.8 meters
What is 1.8 m?
