Example Question #11 : Patterns Of Fertility, Mortality, & Health
Which of these countries is most likely to have a triangular population pyramid?
South Africa
The United Kingdom
Andorra
Liberia
Moldova
Liberia
In a triangular population pyramid, the youngest people in a society make up the highest percentage of that society. It is symptomatic of high birth rates and high death rates, so the best answer choice here is Liberia. South Africa is somewhat more developed than Liberia, so it has a population pyramid closer to a rectangle. The same is true for Moldova and to a greater extent Andorra and the United Kingdom.
Example Question #12 : Patterns Of Fertility, Mortality, & Health
Infant mortality rate is highest in __________.
South America
North Africa
East Asia
North Asia
Sub-Saharan Africa
Sub-Saharan Africa
Infant mortality rate measures how many babies, per thousand births, die before their first birthday. In many parts of Sub-Saharan Africa, the number is as high as one hundred. In almost all of the developed world, this number is less than ten. In what may seem like an illogical paradox, a high infant mortality rate generally correlates to a high rate of population growth—this is in part because when a culture believes many of its children will die before reaching adulthood (or even childhood), people of that culture tend to have more babies.
Example Question #17 : Patterns Of Fertility, Mortality, & Health
The world’s population in 1985 was approximately 5 billion people. With a consistent rate of growth, the total population is expected to reach 10 billion in roughly 35 years–the year 2020.
This period of 35 years is known as __________.
demographic transition rate
doubling time
natural increase rate
life expectancy
doubling time
Since the population is expected to double over the period of those 35 years, it is most appropriate described as "doubling time." Since we know nothing of the death rate, crude or otherwise, we cannot determine the natural increase rate or even speak of life expectancy. Similarly, as we know nothing of the demographics, we cannot determine the demographic transition rate.
Example Question #11 : Patterns Of Fertility, Mortality, & Health
Which of the following accurately describes how to calculate an area's crude birth rate (CBR)?
The number of live births per year for every 10,000 deaths.
The number of total births (both live and stillborn) per year for every 100,000 people alive.
The number of live births per year for every 1,000 people alive.
The number of live births per year for every 100,000 people alive.
The number of total births (both live and stillborn) per year for every 1,000 people alive.
The number of live births per year for every 1,000 people alive.
Crude birth rate (CBR) is the number of live births per year for every 1,000 people alive. When the crude death rate (CDR) is subtracted from the crude birth rate (CBR), you can determine an area's rate of natural increase. A higher CBR indicates population growth in an area, while a higher CDR indicates population decline.
Example Question #161 : Ap Human Geography
Which of the following is not true about infant mortality rate (IMR)?
As a whole, IMR has decreased in most countries over the past 50 years.
Differences in reporting what counts as a "live birth" greatly impacts IMR rates across countries.
The UN estimates that the worldwide IMR is around 50.
IMR is the number of infant deaths (children under 5 years old) per 1,000 live births.
African countries typically have higher IMR.
IMR is the number of infant deaths (children under 5 years old) per 1,000 live births.
IMR is the number of infant deaths (children under 1 years old) per 1,000 live births, not children under 5 years old. According to the UN, the under-5 mortality rate of the world is around 73. All of the other answer choices are true.
Example Question #162 : Population & Migration
What is the term used to designate the proportion of individuals of different ages within a population?
Age ratio
Age numbers
Proportional ratio
Age distribution
Proportional distribution
Age distribution
You can use an age distribution to approximate survival rates by calculating the difference proportion of individuals in age classes.
