Question 1

Christopher's research focuses on the number of deaths that occur in the population. Christopher is examining:

Accepted Answer

Mortality rates refer to the number of deaths in a population, which is exactly what Christopher's research focuses on.

Question 2

Because of the discovery of penicillin, the number of deaths per year for every 1,000 people declined. As such, penicillin impacted the:

Accepted Answer

Penicillin significantly reduced mortality rates by effectively treating previously fatal bacterial infections, thus directly impacting the Crude Death Rate by lowering it.

Question 3

Lois was born in 1954. This means that Lois is classified as (an)________ .

Accepted Answer

Lois, born in 1954, falls within the post-World War II baby boom period, which is approximately from 1946 to 1964, making her a part of the baby boomer generation.

Question 4

Ricardo is doing a research paper on the number of births that occur to unwed mothers. Ricardo is concerned with the_______ of unwed mothers.

Accepted Answer

The fertility rate refers to the number of births per woman, which is relevant when discussing births to unwed mothers.

Question 5

In Japan, the total fertility rate is 1.46. From this, we can conclude that:

Accepted Answer

The total fertility rate of 1.46 in Japan indicates that, on average, each woman is having fewer than two children, which is below the replacement level of approximately 2.1 needed for a stable population, without immigration. This leads to a situation where the population is not growing (below zero population growth), there are not enough births for children to replace their parents, and the country is experiencing a decline in births, often referred to as birth dearth.

Question 6

Dawn is examining the relationship between the level of education and fertility among women. Dawn will find that:

Accepted Answer

Studies and data consistently show that higher levels of education in women are associated with lower fertility rates. This is due to a variety of factors including career priorities, access to family planning information, and delayed marriage and childbearing.

Question 7

Dr. Rodriguez gave his sociology students an assignment. Each student must provide a visual presentation of data related to the age and sex of the population in a different country. The sociology students will turn in:

Accepted Answer

Population Pyramids are graphical representations that show the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing. They are used to illustrate the differences in age and sex composition. This makes them the correct tool for visualizing data related to the age and sex of the population in different countries, as required by Dr. Rodriguez's assignment.

Question 8

Lionel creates a population pyramid and notices that the shape of the graph is rectangular. This means that:

Accepted Answer

A rectangular population pyramid shape indicates that birth rates are stable and people are living longer lives, as the population numbers are relatively consistent across different age groups.

Question 9

The U.S. Census Bureau collects and shares information on the population's size, age, racial composition, birth rates, and death rates. This organization collects data on:

Accepted Answer

The U.S. Census Bureau collects data on demographic variables, which include population size, age, racial composition, birth rates, and death rates.

Question 10

In New Zealand, the total fertility rate is 2. This reflects:

Accepted Answer

A total fertility rate of 2 is generally considered the replacement level fertility, meaning that on average, each woman is having enough children to replace herself and her partner, leading to zero population growth in the absence of migration.

Question 11

Warren thinks that the Alachua County School Board should offer sex education to high school students. To support his case, Warren presented school board members with the number of births for every 1,000 women between the ages of 15 and 18 in the local area. Warren's data represents the:

Accepted Answer

Warren's data specifically focuses on births among a particular age group (women between the ages of 15 and 18), which is a characteristic of the Age-Specific Birth Rate. This rate measures the number of births within a specific age group per 1,000 women in that group, providing targeted information about fertility patterns among that demographic.

Question 12

In the United States, the average number of years that whites are expected to live is greater than that of blacks. This means that there are racial differences in:

Accepted Answer

Life expectancy refers to the average number of years a person is expected to live based on demographic factors, including race. The statement highlights a difference in life expectancy between racial groups.

Question 13

The number of deaths for every 1,000 people between the ages of 65 and 85 in the United States is greater than the number of deaths for every 1,000 people between the ages of 44 and 64. Thus, there is a difference in the_________.

Accepted Answer

The age-specific death rate refers to the number of deaths in a specific age group per 1,000 people in that age group. The statement compares death rates between two different age groups, indicating a difference in age-specific death rates.

Question 14

April wants to know the maximum length of time that a human being can possibly live. She is interested in:

Accepted Answer

Lifespan refers to the maximum length of time an individual from a given species can live. In the context of human beings, it pertains to the maximum age that human beings have been known to reach or could potentially reach, which aligns with April's interest.

Question 15

Professor Klepper asks his students the size of the cohort that they would want their children to be born into, in order to have the best opportunities in education and employment. For increased opportunities, students should desire (an) __________cohoror their children.

Accepted Answer

A small-sized cohort is generally associated with better opportunities in education and employment due to reduced competition for resources, more personalized attention in educational settings, and better job prospects as there are fewer people vying for the same positions.

Question 16

Rose speaks at the high school career fair and tells the student that in her job, she studies population size and composition. What is Rose's field of study?

Accepted Answer

Demography is the study of populations, including their size, composition, distribution, and the changes and causes of these changes. Rose's description of her job aligns with the definition of demography.

Question 17

Professor Zurich informs her demography class that the average number of births that a woman in the population is expected to bear in her lifetime has declined in the past 50 years. Professor Zurich is teaching about the:

Accepted Answer

The Total Fertility Rate (TFR) measures the average number of children a woman is expected to have over her lifetime, which directly relates to the information provided by Professor Zurich about the decline in births per woman over time.

Question 18

When the baby boomers reached the birthing age, there was a surge in the growth of the United States' population. This reflects:

Accepted Answer

Population momentum refers to the continued population growth that occurs after a fertility decline because of the relatively high concentration of people in the childbearing age group. This concept explains the surge in the United States' population when the baby boomers reached birthing age.

Question 19

Because of the famine in Ethiopia, the number of children who died before reaching the age of one year for every 1,000 born alive increased dramatically. This means that the_____ increased.

Accepted Answer

The infant mortality rate is the number of deaths of infants under one year old per 1,000 live births. The scenario described directly relates to an increase in the infant mortality rate due to the famine in Ethiopia.

Question 20

Lauren's job requires her to report the number of births per 1,000 people each year. Lauren focuses on the:

Accepted Answer

Lauren is focusing on the Crude Birth Rate, which is the number of live births per 1,000 people in a population per year. This measure does not account for the age structure of the population.
