total number of farmers per unit of arable land

carrying capacity

a species' average population size in a particular habitat

population pyramid

represents the breakdown of the population by gender and age at a given point in time

demographic

relating to the structure of populations

fertility

the number of live births occurring in a population

mortality

the ratio of the number of deaths in the year to the average total population of the year

birth rates

the ratio between the number of live-born births in the year and the average total population of that year

death rates

indicates the number of deaths occurring during the year, per 1,000 population estimated at midyear

life expectancy

the age a person can expect to live based on the statistical average for an area

dependency ratio

relates the number of children (0-14. years old) and older persons (65 years or over) to the working-age population (15-64 years old)

rate of natural increase

the difference between the number of live births and the number of deaths occurring in a year, divided by the mid-year population of that year, multiplied by a factor (usually 1,000)

population-doubling time

the amount of time it takes for the population of a region to double

DTM stage 1

a low population growth rate due to a high birth rate and a high death rate

DTM stage 2

a rapid decrease in a country's death rate while the birth rate remains high

DTM stage 3

death rates are low and birth rates decrease, usually as a result of improved economic conditions, an increase in women's status and education, and access to contraception

DTM stage 4

birth rates and death rates are both low, stabilizing total population growth

DTM stage 5

a country experiences loss to the overall population as the death rate becomes higher than the birth rate

Malthusian theory

The theory that mass starvation is inevitable because food supplies grow at the same rate while population grows exponentially, leading to the population being much higher than the food supply can handle

Esther Boserup

a famous agricultural geographer who's theory is based on the premise that population growth is a positive force in agricultural innovation, that it drives technology forward

pronatalist

an attitude or policy that encourages childbearing

antinatalist

government policies that discourage couples from having children

contraception

birth control by the use of devices or drugs or surgery

Ravenstein's laws of migration

Most migrants move only a short distance

migration

the movement of people from one place in the world to another

push factors

something that encourages an individual to migrate away from a certain place

pull factors

positive factors that attract people to new areas from other areas

intervening opportunities

a feature that causes a migrant to choose a destination other than his original one

intervening obstacles

n environmental or cultural feature that hinders migration

forced migration

a general term that refers to the movements of refugees and internally displaced people as well as people displaced by natural or environmental disasters, chemical or nuclear disasters, famine, or development projects

slavery

step migration

gradual migration, from farm to village to town to big city

guest worker

foreign national who is permitted to live and work temporarily in a host country

rural-to-urban migration

people choose to move from a less populated area to more densely populated areas which often present more work opportunities, better pay, or a better quality of life

reference map

designed for people to refer to for general information about places

thematic map

show spatial aspects of information or of a phenomenon

absolute distance

The distance that can be measured with a standard unit length, such as a mile or kilometer.

absolute direction

A compass direction such as north or south.

relative distance

Where something is located in relation to other things(same as relative location)

relative direction

Directions such as left, right, forward, backward, up, and down based on people's perception of places

clustering

phenomena are arranged in a group or concentrated areas

dispersal

phenomena are spread out over a large area

elevation

the distance of features above sea level

map projection

the process of showing a curved surface (the earth) on a flat surface (a map). In other words, taking a 3-dimensional object and making it 2-dimensional.

absolute location

exact location of a place on the earth described by longitude and latitude

relative location

Where something is located in relation to other things

Political Map

Shows and labels the human-created boundaries and designations, such as countries, states, cities, and capitals.

Physical Map

Shows and labels the natural features, such as mountains, rivers, and deserts.

Thematic maps

show spatial aspects of information or of a phenomenon

Choropleth Map

Uses various colors, shades of one color, or patterns to show the location and distribution of spatial data

Dot Map

Used to show the specific location and distribution of something across the territory of the map

Graduated Symbol Map

Uses symbols of different sizes to indicate different amounts of something
