B)The mortality for Whites with a high school degree or less is decreasing.
C)The mortality rate or Whites with a college degree is increasing.
D)The mortality rate for women has now caught up with men.

Accepted Answer

The mortality rate for Blacks has been decreasing over time, reflecting improvements in healthcare access, disease prevention, and treatment among other factors. This trend contrasts with certain demographics of Whites, particularly those with lower educational attainment, where mortality rates have been increasing or stagnating, largely due to factors like economic distress, substance abuse, and lack of access to quality healthcare.

Question 5

B)The birthrate remains high or declines more slowly than the death rate.
C)The decline in the death rates leads to more children in the family.
D)The society experiences both low birth and death rates.

Question 10

Alex studies the fertility and migration trends of countries around the world.Which of these describes Alex?
A)environmentalist
B)geographer
C)demographer
D)philosopher

Accepted Answer

Alex's field of study is related to demographics, which is the scientific study of human populations, including their size, growth, density, demographics, and distribution of different age groups. Therefore, Alex is a demographer.

Question 11

In which stage of the demographic transition do birthrates stay high while death rates experience a dramatic decline?
A)first
B)second
C)third
D)fourth

Accepted Answer

In the second stage of the demographic transition, birthrates remain high but death rates start to decline rapidly due to improvements in sanitation, healthcare, and education. This results in a population explosion as the gap between births and deaths widens.

Question 12

What birthrate is necessary to replace the population?
A)1.1
B)2.1
C)3.1
D)4.1

Accepted Answer

The birthrate necessary to replace the population is called the replacement level fertility rate (RLFR). This is the number of children that must be born to each woman in order for the population to replace itself. The RLFR is typically estimated to be around 2.1 children per woman in developed countries. This is because some children will not survive to adulthood, and some people choose not to have children at all. In developing countries, the RLFR may be slightly higher to account for higher rates of infant mortality. Therefore, the best choice is B) 2.1 as it is the most commonly accepted RLFR.

Question 13

Question 15

According to the demographic transition theory,population changes are related to which of these?
A)religion
B)industrialization and urbanization
C)famine
D)gender norms and practices

Accepted Answer

The demographic transition theory explains that population changes are related to industrialization and urbanization, which affect birth and death rates. As societies modernize and become more industrialized, the birth rate tends to decline as people have fewer children and have them later in life. Simultaneously, the death rate tends to decline as medical technology and living standards improve. This creates a period of population growth followed by stabilization as birth and death rates level off.

Question 16

An asylum seeker is a person who has left their home country due to persecution and is seeking protection in another country. A refugee is someone who has fled their home country due to persecution or war and has been granted legal protection in another country. An undocumented immigrant is someone who enters or resides in a country without legal authorization.

Accepted Answer

Better public health interventions such as improved sanitation, access to clean water, and vaccinations have played a significant role in reducing mortality rates in certain countries. The other choices, such as weaker norms around healthy behaviors (A) and negative behaviors like obesity (B) and drug addiction (D) are individual or micro factors that may contribute to health outcomes, but they are not macrosocial factors impacting entire populations.
