Structure of a population in terms of age, sex and other properties such as marital status and education

geographic concepts

Ways of seeing the world spatially that are used by geographers in answering research questions

location theory

a logical attempt to explain the locational pattern of an economic activity and the manner in which its producing areas are interrelated. The agricultural location theory contained in the von Thunen model is a leading example.

pandemic

an outbreak of a disease that spreads worldwide. (see also - endemic)

distance

measurement of the physical space between two places

spatial perspective

observing variations in geographic phenomena across space

generalized map

"When mapping data, whether human or physical geographers, cartographers, the geographers who make maps, generalize the information the present on maps." (de Blij, Murphey, Fouberg, ph 16)

physical geography

one of the two major divisions of systematic geography; the spatial analysis of the structure, processes, and location of the Earth's natural phenomena such as climate, soil, plants, animals, and topography.

spatial

pertaining to space on the Earth's surface; sometimes used as a synonym for geographic

spatial distribution

physical location of geographic phenomena across space

epidemic

regional outbreak of a disease

location

the first theme of geography as defined by the Geography Educational National Implementation Project; the geographical situation of people and things.

place

the fourth theme of geography; uniqueness of a location

sequent occupance

the notion that successive societies leave their cultural imprints on a place, each contributing to the cumulative cultural landscape

activity spaces

the space within which daily activity occurs

fieldwork

the study of geographic phenomena by visiting places and observing how people interact with and thereby change those places

cultural landscape

the visible imprint of human activity and culture on the landscape. The layers of buildings, forms, and artifacts sequentially imprinted on the landscape by the activities of various human occupants.

five themes (of geography)

they are location, human-environment, region, place, and movement

population distributions

Description of locations on the Earth's surface where populations live

laws of migration

Developed by British demographer Ernst Ravenstein, five laws that predict the flow of migrants (become familiar with each of the five laws)

possibilism

Geographic viewpoint—a response to determinism—that holds that human decision making, not the environment, is the crucial factor in cultural development. Nonetheless, possibilists view the environment as providing a set of broad constraints that limits the possibilities of human choice

restrictive population policies

Government policies designed to reduce the rate of natural increase

expansive population policies

Government policies that encourage large families and raise the rate of population growth

cultural hearth

Heartland, source area, innovation center; place of origin of a major culture

internal migration

Human movement within a nation-state, such as ongoing westward and southward movements in the United States

nomadism

Movement among a definite set of places—often cyclic movement

voluntary migration

Movement in which people relocate in response to perceived opportunity, not because they are forced to move

periodic movements

Movement—for example, college attendence or military service—that involves temporary, recurrent relocation

cyclic movements

Movement—for example, nomadic migration—that has a closed route and is repeated annually or seasonally

demographic transition

Multistage model, based on Western Europe's experience, of changes in population growth exhibited by countries undergoing industrialization. High birth rates and death rates are followed by plunging death rates, producing a huge net population gain; this is followed by the convergence of birth rates and death rates at a low overall level

time-distance decay

The declining degree of acceptance of an idea or innovation with increasing time and distance from its point of origin or source

contagious diffusion

The distance-controlled spreading of an idea, innovation, or some other item through a local population by contact from person to person—analogous to the communication of a contagious illness

culture diffusion

The expansion and adoption of a cultural element, from its place of origin to a wider area

stationary population level (SPL)

The level at which a national population ceases to grow

arithmetic population density

The population of a country or region expressed as an average per unit area. The figure is derived by dividing the population of the areal unit by the number of square kilometers or miles that make up the unit

population explosion

relative location

The regional position or situation of a place relative to the position of other places. Distance, accessibility, and connectivity affect relative location

activity spaces

The space within which daily activity occurs

expansion diffusion

The spread of an innovation or an idea through a population in an area in such a way that the number of those influenced grows continuously larger, resulting in an expanding area of dissemination

culture

The sum total of the knowledge, attitudes, and habitual behavior patterns shared and transmitted by the members of a society. This is anthropologist Ralph Linton's definition; hundreds of others exist

independent invention

The term for a trait with many cultural hearths that developed independent of each other

doubling time

The time required for a population to double in size

environmental determinism

The view that the natural environment has a controlling influence over various aspects of human life, including cultural development. Also referred to as environmentalism
