What are the differences between population studies and demography?

Demography is focused on the statistical analysis of population information, this includes the examination of population dynamics such as population size, structure and distribution which illustrate the structural change in population.Population Studies is about studying the number of people in a given area, their characteristics and the changes over time. It seeks explanation for the patterns of variations and the causes of change. It also projects future population size and its consequences.

Distinguish between optimum theory and malthusian theory?

Optimum theory proposes that there is an ideal population size that maximizes societal welfare and economic efficiency, whereas Malthusian theory posits that population growth will outstrip resources leading to famine and suffering unless controlled by preventive checks (like war, disease, or lack of resources) or positive checks (like famine, disease, or war). Optimum theory focuses on the balance between population and resources for societal well-being, while Malthusian theory highlights the consequences of unchecked population growth.

What is Beyer migration theory?

Beyer migration theory, also known as the gravity model of migration, suggests that migration flows between two places are directly proportional to the size of the population in those places and inversely proportional to the distance between them. It provides a framework for understanding and predicting migration patterns based on population size and distance. The theory is widely used in the field of migration studies to analyze and explain migration processes.

What is optimum theory of population?

The optimal theory of population, also known as optimal control theory in economics, aims to find the best way to allocate resources to maximize economic welfare when dealing with population growth and dynamics. This theory considers factors like birth rates, death rates, and migration to determine the ideal population size that maximizes social benefits while minimizing social costs. By using mathematical models and simulations, policymakers can make informed decisions to promote sustainable population growth and development.

What is relative population size?

Relative population size is the size of an area's population as it compares to similar areas' populations. For example, the relative population size of a country would be what rank it had compared to the population of other countries.

WHAT IS THE boserup theory on population?

Boserup theory is known as an optimistic theory. It states that agricultural methods and productivity of food depend on the size of the population. Indications: 1: if population increases, larger workforce so more food produced. 2: if population increases, mechanistaion occurs, more food produced as more effective means found of producing high yields of food through use of machinery. 3: if population increases, increased use of fertilisers results, so as to produce more food for the growing poulation.
