Geographic Data & Systems
This specialized computer mapping software superimposes multiple separate layers of geographic data onto a single location to reveal deep spatial connections and trends.
What is a Geographic Information System (GIS)?
This primary category of diffusion refers to the spread of a cultural trait, innovation, or language through the actual physical migration of people from one place to another.
What is relocation diffusion?
his 18th-century British economist warned that human population grows exponentially while food supplies grow only linearly, inevitably resulting in resource crises.
What is Thomas Malthus?
This German-English geographer analyzed census data from the late 19th century to establish a universally recognized set of foundational laws governing migration.
What is Ernst Georg Ravenstein?
This term refers to the blending and combination of distinct cultural, linguistic, or religious traditions to construct a brand new, unique hybrid trait, such as Vodou or Latin American Catholicism.
What is syncretism?
Gathered via personal interviews, historical texts, and firsthand observations, this type of geographic data focuses heavily on descriptive human experiences rather than statistics.
What is qualitative data?
This expansion diffusion variant occurs when a cultural factor or idea is transmitted rapidly and uniformly across a population, similar to an infectious disease or an internet meme.
What is contagious diffusion?
This influential five-stage model details a country's historical progression from a state of high birth and death rates to low birth and death rates as it modernizes.
What is the Demographic Transition Model (DTM)?
his gradual migration behavior describes a person relocating through a sequence of incremental shorter moves or stages, such as moving from a village to a small town, and then to a major city.
What is step (or stepwise) migration?
This outcome occurs when a minority or immigrant population fully adopts the values, behaviors, and customs of a dominant host culture, resulting in the complete loss of their original cultural identity.
What is cultural assimilation?
This term describes the exact position of a feature on the surface of the Earth as determined by a standard mathematical grid of latitude and longitude coordinates.
What is an absolute location?
This type of diffusion takes place when an underlying concept spreads across cultures but is heavily modified or adapted to fit the local traditions of the receiving society.
What is stimulus diffusion?
This demographic model tracks the historical evolution of human mortality causes, shifting from preventable infectious pandemics to chronic degenerative conditions typical of aging populations.
What is the Epidemiological Transition Model (ETM)?
This process takes place when early successful migrants establish supportive social networks that attract and draw regular flows of friends and family from their hometown to the same destination.
What is chain migration?
This cultural attitude involves evaluating, criticizing, or dismissing another society's traditions and values based entirely on the biased standards of one's own native culture.
What is ethnocentrism?
This formal term refers to the linguistic name identifiers assigned to specific locations on Earth, such as cities, rivers, or mountains.
What is a toponym?
This term defines the diffusion of a cultural practice or innovation into a new area where it is entirely impractical, inefficient, or ecologically destructive.
What is maladaptive diffusion?
This Danish economist directly challenged Malthus by asserting that population growth serves as a vital stimulus for human ingenuity and agricultural innovation.
What is Esther Boserup?
This binding tenet of international refugee law explicitly prohibits host nations from forcibly deporting refugees back to a country where their lives or freedoms are actively endangered.
What is the principle of non-refoulement?
Frequently likened to a "salad bowl," this societal framework encourages multiple separate cultural and ethnic groups to coexist peacefully while maintaining their unique, distinctive identities.
What is multiculturalism?
This highly political practice involves intentionally manipulating and redrawing the boundaries of a voting district to give a distinct advantage to one political party over another.
What is gerrymandering?
This graphical transition model illustrates how the adoption of a diffused cultural element unfolds over time, charting a slow beginning, rapid acceleration, and eventual saturation.
What is the diffusion S curve?
This 20th-century movement revived Malthusian anxieties by highlighting how overpopulation degrades broader planetary systems, clean air, water, and nonrenewable resources.
What is the Neo-Malthusian movement?
Formulated by geographer Wilbur Zelinsky, this model outlines five distinct historical stages of changing spatial mobility options that directly correspond to a society's developmental status.
What is the mobility transition model?
This phrase describes a dominant group adopting elements of a marginalized or minority culture, often entirely out of context and while ignoring its original sacred or historical significance.
What is cultural appropriation?
