Population Distribution Flashcards
Population Density
Population density is the number of individuals per unit area, usually per square kilometer or square mile. It is a crucial metric for understanding the intensity of human habitation in a given space.
Population Distribution
Population distribution refers to the pattern or arrangement of people across a particular area. It considers factors such as density, concentration, and dispersion.
Global Population Patterns
The global population is not evenly distributed. Some regions, like Asia, have high population density, while others, like Antarctica, are sparsely populated.
Urbanization
Urbanization is the process of increasing the proportion of people living in urban areas compared to rural areas. It is often linked to industrialization and economic development.
Rural Depopulation
Rural depopulation occurs when people leave rural areas for urban opportunities, leading to a decline in the rural population. This phenomenon is often associated with modernization.
Demographic Transition Model
The demographic transition model explains how populations change over time. It includes stages of high birth and death rates, followed by declining birth and death rates as societies develop.
Natural Increase
Natural increase is the difference between birth rates and death rates in a population. A positive natural increase contributes to population growth.
Migration Patterns
Migration patterns influence population distribution. Internal migration involves movement within a country, while international migration involves movement between countries.
Ageing Population
An ageing population has a higher proportion of elderly people compared to young individuals. This demographic shift often poses social and economic challenges.
Youthful Population
A youthful population has a higher proportion of young individuals. While it may indicate potential for economic growth, it can also strain resources like education and healthcare.
Megacities
Megacities are cities with populations exceeding 10 million. They often face challenges related to infrastructure, housing, and services due to rapid urbanization.
Carrying Capacity
Carrying capacity is the maximum population size that an environment can support sustainably. It is influenced by factors like resources, technology, and human activities.
Population Pyramid
A population pyramid is a graphical representation of a population’s age and gender structure. It helps analyze demographic trends and predict future population changes.
Infant Mortality Rate
The infant mortality rate is the number of deaths of infants under one year old per 1,000 live births. It is an important indicator of a population’s health and living conditions
Life Expectancy
Life expectancy is the average number of years a person can expect to live. It is influenced by factors like healthcare, nutrition, and overall quality of life.
