Question 1

Which industrialized nation is expected to show the most dramatic increase in the percent of its population over age 65?

Accepted Answer

Japan is expected to have the most dramatic increase in the percent of its population over age 65. In 2019, 28% of its population was over age 65, and this is projected to increase to 35% by 2050. This is due to factors such as low birth rates and high life expectancies.

Question 2

Based on data gathered from the Human Genome Project, researchers have attempted to increase longevity and health through

Accepted Answer

Based on data gathered from the Human Genome Project, researchers have attempted to increase longevity and health through implanting genetically "corrected" genes. This approach involves identifying and targeting specific faulty genes that may lead to certain diseases or health conditions, and replacing them with properly functioning ones. This has the potential to address genetic causes of aging and disease, and has shown promising results in animal studies. Cloning and organ transplant are not directly related to genetic modification, and while diet can impact overall health, it is not directly related to genetic intervention aimed at prolonging life.

Question 3

Environmental toxins appear to play _____ role in determining longevity.

Accepted Answer

D

Question 4

Chatava is a professional who does research to determine the numbers of people in different countries, their ages, and how these numbers might change in the years to come. Chatava would best be described as a

Accepted Answer

Chatava's profession is to study population, which makes them a demographer. A social worker helps people deal with social problems, a metabolic theorist studies metabolic processes, and a cartographer makes maps.

Question 5

As a demographer, Sherwood would be most interested in studying

Accepted Answer

Demography is the study of human populations, including their size, composition, and distribution. Therefore, Sherwood would be most interested in studying how the number of young people in a population has changed over the past 50 years, as it relates to population trends and changes.

Question 6

In the country of Casfeldt, 50 percent of the population who died in 2002 were older than 85. Thus, 85 would be the _____ life expectancy.

Accepted Answer

Life expectancy refers to the average number of years a person is expected to live. In this case, the fact that 50 percent of those who died in 2002 were older than 85 suggests that the average life expectancy in Casfeldt is likely to be around 85 years. Option A (maximum) refers to the highest possible age a person can reach, which is not relevant to the given information. Option B (useful) and option D (modal) do not accurately reflect the concept of life expectancy.

Question 7

Useful life expectancy is defined as the number of years an individual

Accepted Answer

Useful life expectancy is defined as the number of years an individual is able to live free from debilitating chronic disease or impairment. This term specifically focuses on a person's ability to carry out everyday activities without limitations, rather than their ability to contribute to the workforce or their living situation.

Question 8

Which headline concerns maximum life expectancy?

Accepted Answer

The answer of Which headline concerns maximum life expectancy?
...

Question 9

As the over-80 population increases dramatically in the next 40 years, which will probably be most affected in the United States?

Accepted Answer

The social service systems, which include healthcare, eldercare, and support for seniors, will probably be most affected by the increase in the over-80 population. This demographic shift will strain healthcare resources, as older Americans tend to have higher healthcare needs, and there will be increased demand for eldercare services, such as assisted living facilities and home healthcare aides. Additionally, as more seniors retire and rely on social security, there may be challenges in funding these programs.

Question 10

Question 11

Marty asks his doctor, "How long do you think I can live, doc?" Marty is asking for information regarding his

Accepted Answer

Marty's question is specifically asking about how long he can expect to live, which is referred to as his longevity.

Question 12

Longevity appears to be determined

Accepted Answer

Longevity is determined by a combination of genetic and environmental factors. Studies have shown that while genes can play a role in lifespan, lifestyle factors such as diet, exercise, and social connections also have a significant impact on how long people live.

Question 13

If you were in charge of developing programs aimed at elderly individuals in the United States, for which group would you least plan to expand services in the next decade?

Accepted Answer

European Americans are the largest demographic group among the elderly in the United States, and their population growth rate is slower compared to other minority groups. Therefore, there may be less need to expand services specifically for them compared to other groups that are growing more rapidly.

Question 14

In order to depict the number of people of different ages in the population, Dr. Gillen would be best served using a graphing technique called a(n)

Accepted Answer

A population pyramid is a graphing technique used to depict the number of people of different ages in the population. It is often used in demography to analyze and better understand the structure and composition of a population. Presbycusis is a type of age-related hearing loss and external aid refers to any device or tool that assists individuals with physical or cognitive disabilities.

Accepted Answer

Studies have shown that genetic factors play a major role in determining whether people reach centenarian status. While environmental factors such as lifestyle and diet also play a part, genetics seem to have the strongest influence on longevity.

Question 19

In 1950, the population distribution of the United States resembled a(n)

Accepted Answer
