Human Geography

The study of how people and their activities differ from place to place around the world.

Spatial Perspective

A geographic approach where geographers ask about the 'why of where' to analyze why activities happen in specific locations and how nearby places interact.

The exact position of a place on Earth's surface, typically determined by coordinates on a grid system of latitude and longitude.

Cartography

The discipline and methodology of creating maps.

Topographic Map

A type of reference map that uses isolines to connect points of equal elevation to assist with navigation and land planning.

Absolute Distance

The measurable spatial separation between two points expressed in standard units like miles or kilometers.

Accessibility

A measure of how easily one location can be reached from or influenced by another location.

Distance Decay Effect

The phenomenon where the interaction between two places decreases as the physical distance between them increases.

Time-Space Compression

The reduction of the impact of physical distance caused by technological advancements in transportation and communication.

Relative Location

The description of a place's position based on its location relative to nearby features or landmarks.

Spatial Data

Physical information about a location derived from references such as maps, satellite images, and GPS coordinates.

Non-spatial Data

Descriptive characteristics of a location that do not specify exact position, such as population demographics, income, or land use.

Toponym

The name identifier given to a specific location or natural feature.

Cultural Landscape

A geographic area, including both natural and built environments, modified by human development to reflect a society's culture.

Gerrymandering

The intentional drawing of voting district boundaries to provide an unfair political advantage to a specific political party.

Relocation Diffusion

The spread of cultural traits, languages, ideas, or innovations through the physical movement and migration of people.

Expansion Diffusion

The process by which an idea or cultural innovation originates from a central hearth and spreads outward to new locations.

Environmental Determinism

The belief that the natural environment determines human lifestyles, capabilities, and levels of societal development.

Environmental Possibilism

The perspective that while the physical environment sets limits on human development, humans can adapt and shape possibilities through technology and innovation.

Formal Region

An area defined by a shared, measurable characteristic—such as language, climate, or political boundaries—that is consistent throughout the region.

Functional Region

An area organized around a central focal point or node that coordinates movement, activity, transportation, or economic systems.

Vernacular Region

A region defined by shared cultural perceptions, informal identity, and subjective perspectives rather than formal boundaries.

Material Culture

The physical components of culture created and used by humans, including tools, apparel, architecture, and artwork.

Nonmaterial Culture

The non-physical components of culture, including shared beliefs, moral principles, values, language, and social institutions.

Cultural Hearth

The original geographic origin point where a specific culture, innovation, or set of practices first developed.

Ethnocentrism

The practice of judging another culture's values, customs, and behaviors against the standards and values of one's own culture.

Cultural Relativism

The practice of evaluating and understanding a culture based on its own internal standards and values.

Lingua Franca

Universalizing Religion

A faith system—such as Christianity, Islam, Buddhism, or Sikhism—that actively seeks converts globally regardless of culture or ethnicity.

Ethnic Religion

A faith system—such as Hinduism, Judaism, or Shinto—tied to a specific ethnic group or geographic location that does not actively seek global conversion.

Creolization

The process through which distinct cultures interact and merge over time to create new, hybrid cultural forms.

Syncretism

The blending of distinct religious, cultural, or philosophical traditions to create a new, unified synthesis.

Arithmetic Density

A population measure calculated by dividing the total population of a place by its total land area.

Physiological Density

A population measure calculated by dividing the total population of an area by its total arable (farmable) land.

Agricultural Density

A measure of farming efficiency calculated by dividing the total number of farmers by the total area of arable land.

Total Fertility Rate (TFR)

The average number of children born to a woman who survives her childbearing years.

Crude Birth Rate (CBR)

The annual number of live births per $1,000$ individuals in a population.

Crude Death Rate (CDR)

The annual number of deaths per $1,000$ individuals in a population.

Infant Mortality Rate (IMR)

The percentage of infants in a population who do not survive their first year of life.

Natural Increase Rate (NIR)

The annual percentage population growth calculated by subtracting the crude death rate from the crude birth rate, expressed as $CBR - CDR$.

Doubling Time

The number of years needed for a population to double in size, calculated using the rule of 70 as $70 \frac{}{\text{NIR}}$.

Net Migration

The difference between the total number of immigrants and emigrants in a country or region during a set timeframe, formulated as $\text{immigrants} - \text{emigrants}$.

Malthusian Theory

The theory proposed by Thomas Malthus stating that exponential population growth will outpace linear food production, leading to food shortages and positive or preventative checks.

Pronatalist Policy

A government policy aimed at increasing birth rates by offering financial, legal, or medical incentives to encourage families to have more children.

Antinatalist Policy

A government policy designed to reduce birth rates and curb population growth, such as China's former one-child policy.

Replacement Fertility Rate

The average total fertility rate—typically around $2.1$ children per woman—needed for a population to exactingly replace itself from one generation to the next.

Spatial Mobility

A broad term covering all forms of human geographic movement, ranging from short-term daily commuting to long-term relocation across international borders.

Migration Stream

A well-defined flow of migrants moving from a shared geographic origin to a common destination during a given period.

Step Migration

A process in which migrants move in incremental stages or steps toward a final destination rather than making a single direct move.

Chain Migration

A migration phenomenon where early migrants established in a new place inspire and assist relatives or community members from their origin to follow them.

Ravenstein's Laws of Migration

A series of empirical rules formulated by Ernst Georg Ravenstein outlining general spatial trends, motivations, and patterns of human migration.

Migration Selectivity

The tendency for migration to favor individuals possessing specific demographic traits, such as being younger, more educated, and more skilled.

Mobility Transition Model

A theoretical model proposed by Wilbur Zelinsky linking shifts in a country's internal and international migration patterns to its stage of economic development.

The loss of educated, skilled, and productive individuals from a home country due to high rates of out-migration.

Remittances

Monetary earnings transferred by international or domestic migrant workers back to family members in their origin country.

Cumulative Inertia
