One of the following is not of the important characteristics of a population:
Correct Answer
E. None of the above.
Explanation
The given options list important characteristics of a population, including size, growth, and the distribution of its members according to age, sex, and urban/rural status.

2.
Demography studies many statistics, except:
Correct Answer
C. Life expectancy.
Explanation
Demography is the study of human populations and their characteristics. It focuses on analyzing various statistics related to populations, such as births, deaths, migration, and population growth. Income is also an important factor that demographers study to understand the economic conditions of different populations. However, life expectancy is not typically considered a statistic in demography, as it is more closely associated with the field of public health. Therefore, the correct answer is "Life expectancy."
3.
High number of children in the population reflects high fertility.
Correct Answer
B. True
Explanation
A high number of children in the population reflects high fertility because fertility refers to the ability to conceive and give birth to children. If there are a lot of children in a population, it suggests that there is a high rate of fertility among the individuals in that population.

Correct Answer
D. Cancer.
Explanation
Cancer is not a communicable disease because it is not caused by a pathogen or infectious agent that can be transmitted from one person to another.

6.
Reduction of ageing population indicates lower expenditure on the care of the aged.
Correct Answer
A. True
Explanation
The statement suggests that if the ageing population is reduced, there will be lower expenditure on the care of the aged. This is because with fewer elderly individuals, there will be a smaller number of people requiring healthcare and support services, resulting in reduced costs. Therefore, the statement is true.
7.
Sex ratio is affected by all of the following except :
Correct Answer
A. Differential patterns of morbidity for males and females.
Explanation
The sex ratio is a measure of the number of males to females in a population. It is influenced by various factors such as sex ratio at birth, patterns of migration, and patterns of mortality. However, the differential patterns of morbidity for males and females do not directly affect the sex ratio. Morbidity refers to the incidence of illness or disease in a population, and it does not directly impact the ratio of males to females. Therefore, the correct answer is "Differential patterns of morbidity for males and females."
8.
Leading causes of death include all of the following except:

11.
Different age-sex compositions result in:
Correct Answer
E. All of the above.
Explanation
The different age-sex compositions of a population can have various effects. It can lead to different proportions of the population being part of the labor force, as certain age groups or genders may have higher or lower participation rates. Additionally, different age-sex compositions can result in different medical or health problems, as certain groups may be more susceptible to certain illnesses or conditions. This, in turn, can lead to different medical needs and requirements for healthcare services. Therefore, all of the options mentioned in the question can be consequences of different age-sex compositions.
12.
A population can be defined as:
Correct Answer
A. A group of individuals or items that share one or more characteristics from which data can be gathered and analyzed.
Explanation
The correct answer is "A group of individuals or items that share one or more characteristics from which data can be gathered and analyzed." This definition accurately describes a population, as it emphasizes the common characteristics that individuals or items within the group share. It also highlights the importance of being able to gather and analyze data from this group, which is a key aspect of studying populations in various fields such as sociology, biology, and statistics.
13.
Unhealthy Lifestyle Factors:
Correct Answer
E. All of the above.
Explanation
The given answer, "All of the above," is correct because all the mentioned factors - sedentary life, stress, unhealthy diet, and smoking - contribute to an unhealthy lifestyle.

Diseases like cardiovascular diseases, cancer, and respiratory diseases are responsible for a significant number of deaths globally. However, it is important to note that tobacco use remains a significant public health concern, and efforts to reduce tobacco consumption and its associated health risks should continue.
15.
Which of the following is incorrect about life expectancy:
Correct Answer
C. Males have higher life expectancy than females.
Explanation
The given answer is incorrect because it states that males have higher life expectancy than females, which is not true. On average, females tend to have a higher life expectancy than males. This is supported by various studies and demographic data from around the world. Factors such as biological differences, lifestyle choices, and healthcare access contribute to this difference in life expectancy between males and females.
16.
Crude birth rate can be defined as:
Correct Answer
E. The total live births in a population in a specified community or area over a specified period of time.
Explanation
The correct answer is the total live births in a population in a specified community or area over a specified period of time. This definition accurately describes the concept of crude birth rate, which measures the number of live births in relation to the population size. It is expressed as a ratio per 1000 population per year, indicating the birth rate within a specific time frame. This measure helps understand population growth and demographic trends in a particular area.
17.
An age-population ratio of those typically not in the labor force is a definition of:
Correct Answer
A. Dependency ratio.
Explanation
The age-population ratio of those typically not in the labor force refers to the dependency ratio. This ratio measures the number of economically dependent individuals, such as children and the elderly, compared to the working-age population. It is used to assess the burden on the working population to support those who are not economically active. Family planning services, morbidity, and mortality are not directly related to this concept.
18.
The true statement about demographic transition model is:
Correct Answer
D. A and C.
Explanation
The correct answer is A and C. The demographic transition model consists of four stages and is used to explain the process of transition from both low birth rates and low death rates to high birth rates and high death rates, as well as from high birth rates and high death rates to low birth rates and low death rates.
19.
GBD is:
Correct Answer
D. Two of the above.
Explanation
The correct answer is "Two of the above." This is because GBD, which stands for Global Burden of Disease, serves two purposes. Firstly, it provides a comprehensive understanding of the factors that contribute the most to good health. Secondly, it identifies the most significant health problems. Therefore, the answer "Two of the above" accurately describes the functions of GBD.
20.
One of the following is incorrect about demography:
Correct Answer
C. Does not change over time.
Explanation
Demography is the statistical study of living populations and sub-populations, encompassing the study of their size, structure, and distribution. It is affected by various factors such as birth, migration, aging, and death. However, the statement "Does not change over time" is incorrect because demography is dynamic and constantly evolving. The size, structure, and distribution of populations change over time due to various social, economic, and environmental factors. Therefore, the correct answer is that demography does change over time.
21.
Health policies aims for:
Correct Answer
E. A and B.
Explanation
The correct answer is A and B. Health policies aim to promote health and modify health-related behaviors. This means that they focus on improving overall well-being and encouraging individuals to adopt healthy habits. Disease promotion is not a goal of health policies, as they aim to prevent and reduce the occurrence of diseases. Therefore, the correct answer is A and B, as health policies aim for health promotion and modifying health-related behaviors.
