The ratio of the number of farmers to the total amount of land suitable for agriculture.
The time when human beings first domesticated plants and animals and no longer relied entirely on hunting and gathering.
Arithmetic Density/Arithmetic Population Density
The total number of people divided by the total land area. This is also called the population density. Geographers rely on it to compare conditions in different countries
The total number of individuals of a given species a region can sustain.
A survey conducted by the government, designed to estimate the population, CBR, and CDR.
Child Mortality Rate
The annual number of deaths of children under 1 year of age.
A disease of long duration and generally slow progression.
Crude Birth Rate (CBR)
The total number of live births in a year for every 1,000 people alive in the society.
Crude Death Rate (CDR)
The total number of deaths in a year for every 1,000 people alive in the society.
The phenomenon of continued population increase despite reduced reproduction rates.
Demographic Transition Model
Describes how population mortality and fertility decline as social and economic development occurs through time.
The scientific study of population characteristics.
The number of people who are too old or too young to work, compared to the number of people in their productive years.
A map showing by dots the locations where individuals of a species have been found and recorded.
The amount of time it takes for a population to double.
The portion of Earth's surface occupied by permanent human settlement.
The shift in cause-of-death patterns that comes with the over-all decline of death rates.
The branch of medicine that deals with incidence, distribution, and possible control of diseases and other factors relating to health.
The conjunction of major improvements in industrial technology that transformed the process of manufacturing goods and delivering them to market.
Infant Mortality Rate (IMR)
The number of infants that die in the first 3 months, per 1000.
Measures the average number of years a newborn infant can expect to live at current mortality levels.
When medical technologies entered the LDC's and allowed people to live longer and healthier.
A large populated city in an urban complex.
Natural Increase Rate (NIR)
The percentage by which a population grows in a year. The CDR is subtracted from the CBR to determine the NIR.
When the population of a place exceeds the environment's capacity to support the amount of people with a acceptable standard of living.
A disease that occurs over a wide geographic area and affects a very high proportion of the population.
Physiological Density/Physiological Population Density
Population density in inhabited and cultivated.
The distribution within a group of people of specified individual attributes such as sex, age, marital status, education, occupation, and relationship to the head of household.
Overpopulation is a condition where an organism's numbers exceed the carrying capacity of its habitat. In common parlance, the term usually refers to the relationship between the human population and its environment, the Earth.
A bar-graph that shows the population of age groups. It can be split by gender.
Restrictive Population Policies
Governmental policies that are aimed at restraining population growth so as to prevent overpopulation.
The amount of males per hundred females in a region.
Standard of Living
A level of material comfort, measured by the goods, services, and luxuries available to an individual, group, or nation.
Eugenic Population Policy
Policy that encourages some groups of people to have babies and discriminates against other groups, discouraging their reproduction.
Expansive Population Policies
Government policies that encourage large families and raise the rate of poluation growth.
Stationary Population Level
The level at which national population ceases to grow.
Total Fertility Rate (TFR)
The average number of children a woman will have throughout her childbearing years.
Zero Population Growth (ZPG)
When the crude birth rate and the crude death rate are equal and the natural increase rate equals zero.
