death

the difference between number of births and deaths

The number of years it takes a population to double; calculated by dividing the number 72 by the rate of natural increase

a model of how the size of a population changes as a country develops its economy

hunting and gathering society, in which a society has a low total population with fluctuations in both the birth and death rates. When the birth rates are high the death rates are low & vice versa. Example: No countries in this stage.

agricultural society, birth rates remain high but death rates decline because of more stable food sources and the diffusion of modern medicine (birth rates & death rates remain higher than the world average) & technology.Example: Nigeria

industrial society, birth rates start to decline while death rates continue to decline, factories and economies become important (birth/death rates are around the world averages)Example: Brazil

tertiary (service-based) societies, birth rates and death rates are almost equal, no longer an industrial society, rather it has shifted towards post-industrial.Example: USA

low death rates, very low birth rates, decrease in natural increase rate.Example: Japan

The theory that says that there is a distinct cause of death in each stage of the demographic transition model. It can help explain how a country's population changes so dramatically.

Pestilence, famine, and human conflict cause high CDR.

Receding pandemics with improved sanitation and nutrition, rapidly declining CDR

Degenerative and human created diseases. Decrease in human deaths from infectious diseases and an increase in chronic disorders.

medicine delays degenerative diseases; life expectancy reaches a peak

a proposed stage of reemergence of infectious and parasitic diseases and some become resistant to antibiotics; CDR increases

The theory that population grows faster than food supply
