Demographic Transition Model

These flashcards cover crucial vocabulary related to the Demographic Transition Model and its stages, definitions, and implications.

Demographic Transition Model

A model describing how birth rates and death rates change over time, typically divided into four or five stages.

Stage 1

Characterized by high mortality and high birth rates, with little to no population growth.

Stage 2

Mortality rates fall while birth rates remain high, leading to rapid population growth.

Stage 3

Birth rates begin to decline as mortality rates remain low, causing a decrease in the rate of population growth.

Stage 4

Both birth and death rates are low, stabilizing the population growth, with a beehive-shaped population pyramid.

Stage 5

A potential stage where fertility rates drop below replacement level, leading to a shrinking population.

Population Pyramid

A graphical representation of the age and sex distribution of a population.

Fertility Rate

The average number of children born to a woman over her lifetime.

Mortality Rate

The frequency of death in a given population over a specified period.

Socio-economic Modernization

The process of transition to modern economies and social structures, affecting demographic factors.

High-Effectiveness Medication

Medicines that have been widely used to lower mortality rates in developing countries.
