Final answer:
Demography is the statistical study of human populations, encompassing size, distribution, and structure, and involving the analysis of birth rates, death rates, and migration patterns.
Step-by-step explanation:
Demography is the statistical study of human populations. It explores how populations change over time and space, including aspects such as birth rates, death rates, and life expectancies. By studying these demographic factors, we can gain insights into population growth, migration patterns, and changes in population structure.
Demographic Transition is a model that demographers use to represent the progression of a population from high birth and death rates to lower birth and death rates as a country develops from a pre-industrial to an industrialized economic system. Demography involves the application of statistical tools to understand population dynamics and is an intrinsic part of human geography, sociology, economics, and other disciplines that examine human societies.
