Geographic Terms
The number of people living per unit area of land, usually expressed as people per square kilometer or mile. It indicates how crowded or sparse a population is in a specific area.
Population Density
A type of thematic map that uses different shades or colors to represent data values across geographic areas, such as countries or regions. It is commonly used to visualize statistical data, such as income levels, election results, or disease prevalence, across different areas.
Choropleth Map
A bar graph that displays the age and gender distribution of a population. The graph typically has two back-to-back bars, one for males and one for females, with age groups on the vertical axis. It helps visualize the population structure and can indicate trends such as aging populations or high birth rates.
Population Pyramid
People often migrate internally to find better job prospects, higher wages, or career advancement in urban or industrial areas.
Economic Opportunity
Individuals may migrate to countries with stable governments to escape political unrest, persecution, or conflict in their home countries.
Political Stability
A model that describes the changes in birth rates, death rates, and population growth as a country develops economically. The model typically includes four stages: pre-industrial, transitional, industrial, and post-industrial
Demographic Transition
A map that focuses on a specific theme or subject, such as population density, climate, economic activities, or vegetation. It uses various symbols, colors, and patterns to represent data related to the chosen theme, helping to analyze specific geographic information.
Thematic Map
A graph that shows population change over time by plotting data points along a continuous line. The horizontal axis usually represents time (years), while the vertical axis represents population size. This graph is useful for identifying trends, such as periods of rapid growth, decline, or stabilization in population size.
Line Graph
Access to better educational institutions or specialized training programs can drive internal migration, especially for younger populations. .
Education
Individuals may move to countries where they can freely practice their religion, culture, or lifestyle without discrimination or restrictions.
Cultural and Religious Freedom
The process by which an increasing percentage of a population comes to live in cities and towns, often driven by the movement of people from rural to urban areas in search of better economic opportunities.
Urbanisation
A detailed map that represents the Earth's surface using contour lines to show elevation and landforms. It provides information about the terrain, including hills, valleys, and plains, making it useful for activities like hiking and engineering
Topographic Map
A circular graph that divides a population into segments representing different categories, such as age groups, ethnic groups, or migration status. Each segment's size is proportional to the category's share of the total population. Pie charts are effective for showing the composition of a population at a specific point in time.
Pie Chart
Natural disasters, climate change, or resource depletion can force people to migrate internally to safer or more sustainable areas
Environmental Factors
Individuals may migrate to countries with better healthcare, education, infrastructure, and overall living conditions, seeking an improved quality of life.
Quality of Life
The spread of cultural beliefs, practices, and innovations from one group or society to another. This process can occur through trade, migration, war, or other forms of contact.
Cultural Diffusion
A map that displays the natural features of the Earth, such as mountains, rivers, lakes, and deserts. It focuses on the physical landscape, using color and shading to represent different elevations and terrain types.
Physical Map
A graph that uses bars of different lengths to represent the population size of different categories, such as countries, regions, or age groups. Each bar represents a specific category, allowing for easy comparison of population sizes across those categories.
Bar Graph
The presence of family, friends, or cultural communities in a particular region can influence people to migrate internally to be closer to their support systems.
Social Networks
People fleeing persecution, war, or natural disasters may seek asylum or refugee status in another country for protection and safety.
Asylum and Refuge
The arrangement of various phenomena or features across the Earth's surface. It examines patterns and relationships in how things like population, resources, or land use are distributed geographically.
Spatial Distribution
A map that shows the boundaries of countries, states, and other political units. It highlights major cities and capitals and is often used to understand governmental divisions and the relationships between them.
Political Map
A graph that shows the relationship between two variables, such as population density and economic development. Each point on the graph represents a data pair, with one variable plotted on the horizontal axis and the other on the vertical axis. Scatter plots are useful for identifying correlations and patterns between different factors affecting population changes.
Scatter Plot
People may migrate internally to areas with better facilities, services, and overall access to medical care, especially if they require specialized treatment.
Healthcare Access
People may migrate to join family members who have already settled in another country, seeking to reunite and live together.
Family Reunification
