Question

The scientific method of study of human population is

• A. . Demography
• B. . Sociology
• C. . Ecology
• D. . Anthropology

Hint:

Demography = "demo" (people) + "graphy" (writing/description) $\rightarrow$ statistical description of populations. Sociology = "socio" (society) + "ology" (study) $\rightarrow$ study of society.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question asks for the scientific discipline concerned with the statistical study of human populations.

Step 3: Detailed Explanation:
* Demography: This is the statistical study of human populations, especially with reference to size, density, distribution, and vital statistics (births, deaths, migration, aging). It analyzes population dynamics and characteristics.
* Sociology: This is the study of human society, social behavior, patterns of social relationships, interaction, and culture.
* Ecology: This is the scientific study of the relationships between living organisms and their environment, often focusing on population dynamics in broader ecosystems.
* Anthropology: This is the study of humanity, human behavior, human biology, cultures, societies, and linguistics in both the present and past.
Therefore, the scientific method of study of human population is demography.

Step 4: Final Answer:
The study is Demography.

Answer 2

This question asks for the scientific field that studies human populations using statistics, such as their size and how they change over time. Comparing what each option actually measures helps narrow it down.

1. Demography: This field uses numbers and statistics to study populations, tracking things like birth rates, death rates, migration, and age structure. This statistical focus on population data is exactly what the question describes.
2. Sociology: This studies how people behave in groups, their relationships, and culture, which is broader than just counting and measuring population statistics.
3. Ecology: This studies how living things, including but not limited to humans, interact with their environment, and is not focused specifically on human population statistics.
4. Anthropology: This studies human cultures, evolution, and behaviour, often historically or across societies, rather than the statistical measurement of population data.

Since demography is defined specifically by its statistical study of population size, structure, and change, it is the field being asked about.

Therefore, the correct answer is Demography.
