Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time.
The difference between population and demography is that population is the people living within a political or geographical boundary while demography is the study of human populations, and how they change.
Many of the indexes used in demography (life expectancy at birth, total fertility rate) translate aggregate-level processes into statements about the demographic circumstances faced by an average or randomly-chosen individual.
In Stage 1, which applied to most of the world before the Industrial Revolution, both birth rates and death rates are high, resulting in a constant but fluctuating population.
In Stage 2, the introduction of modern medicine lowers death rates, especially among children, while birth rates remain high, resulting in rapid population growth.
In Stage 3, birth rates gradually decrease, usually as a result of improved economic conditions, an increase in women’s status, and access to contraception.
Consequences of Population Growth include Investment, Overuse of Resources, Urbanization, Per Capita Income, Standard of Living, Agricultural Development, Employment, Social Infrastructure, Labor Force, Capital Formation.
Human patterns of movement reflect the conditions of a changing world and impact the cultural landscapes of both the places people leave and the places they settle.
In order to study how the world population changes over time, it is useful to consider the rate of change rather than focusing only on the total population level.
