The total number of people divided by total land area (also called population density)
Crude Birth Rate
The total number of live births in a year for every 1,000 people alive in the society
Demographic Transition Model
Refers to the stages in which each country passes concerning development and population.
stage 1: Low Growth
stage 2: High Growth
stage 3: Moderate Growth
stage 4: Low Growth
stage 5: No Growth- Negative growth
The number of people who are too young or too old to work, compared to the number of people in their productive years
The rate of natural increase affects the ________________, which is the number of years needed to double a population, assuming a constant rate of natural increase.
Infant Mortality Rate
The annual number of deaths of infants under 1 year of age compared with total live births.
The average number of years a newborn infant can expect to live at current mortality levels
Natural Increase Rate
The percentage by which a population grows in a year. Computed by subtracting the CDR from CBR.
Not just the total number of people on Earth but also includes to relationship between the number of people and the availability of resources
Normally shows the percentage of the total population in 5-year age groups, with the youngest group (0 to 4 years old) at the base of the pyramid and the oldest group at the top.
The range or distribution of a species is the geographical area within which that species can be found.
The geometric expansion of a biological population, especially the unchecked growth in human population resulting from a decrease in infant mortality and an increase in longevity
Total Fertility Rate
Average number of children a woman will have throughout her child-bearing years.
The time when human beings first domesticated plants and animals and no longer relied entirely on hunting and gathering.
The number of years needed to double a population, assuming a constant rate of natural increase.
Focuses on distinctive causes of death in each stage of the DTM.
stage 1: pestilence and famine
stage2: Receding pandemics (industrial revolution)
stage 3: Degenerative and human created diseases
stage 4: delayed degenerative diseases
stage 5: Reemergence of infectious and parasitic diseases
Expansive population policies
Government policies that ENCOURAGE large families and raise the rate of population
Began in England in the late eighteenth century and spread to the European continent and North America during the nineteenth century. Major improvements in industrial technology. Resulted in uprecedented levels of wealth and healthier places to live.
Also known as communicable diseases, contagious diseases or transmissible diseases comprise clinically evident illness resulting from the infection, presence and growth of pathogenic biological agents in an individual host organism.
Group of people in favor of Malthus's theories that describe how unchecked population growth is exponential (1→2→4→16) while the growth of the food supply was expected to be arithmetical (1→2→3→4).
Medical technology invented in Europe and North America diffused to less developed countries in Africa, Asia, and Latin America. Result was improved medical practices eliminated many of the traditional causes of deaths in LDCs.
Newborn Mortality Rate
The number of newborns dying under 28 days of age divided by the number of live births that year.
The description of the population defined by characteristics such as age, sex, and race
Stationary Population Level
The level at which a national population ceases to grow. ALSO- when the crude birth rate equals the crude death rate and the natural increase rate approaches zero. (Aka Zero population growth; Often applied to countries in stage 4 of the demographic transition model)
Restrictive population policies
Policies that restrict the growth of a population, usually enforced by the government or ethnic group, such as the communist Chinese "One Child Policy"
