Definition
| total number of live births in a year for every 1,000 people alive in the society. A CBR of 20 means that for ever 1,000 people in a country, 20 babies are born over a 1 - year period |
|
|
Term
|
Definition
| Crude Death Rate (CDR)- total number of deaths in a year for every 1,000 people alive in the society. Comparable to the CBR, the CDR is expressed as the annual number of deaths per 1,000 population. |
|
|
Term
| Natural Increase Rate(NIR) |
|
Definition
| percentage by which a population grows in a year. It is computed by subtracting CDR from CBR, after first converting the two measures from number per 1,000 to percentages. The term natural means that a country's growth rate excludes migration. |

Term
|
Definition

|
Term

Definition
| time when human beings first domesticated plants and animals and no longer relied entirely on hunting and gathering. |
|
|
Term
|
Definition
| The CDR suddenly plummets, while the CBR remains roughly the same as stage 1. Because the difference between the CBR and CDR is suddenly very high, the NIR is also very high, and population grows rapidly. Countries entered stage 2 as a result of the Industrial Revolution. Some countries moved to stage 2 by the medical revolution. |

|
|
Term
|
Definition
| Sudden drops of CBR. People choose to have fewer children. This decision is a delayed reaction to a decline in mortality, especially the IMR. |
|
|
Term
|
Definition
| CBR declines to the point where it equals the CDR, and the NIR approaches zero. This condition is called zero population growth.Women move from homemakers, and enter the labor force. Smaller families are created. |
|
|
Term
| Zero Population Growth (ZPG) |

Term
| What sort of epidemics occur in Stage 1? |
|
Definition
| This occurred during the Stage 1 of Demographic Transition, or where hunter-gatherers ruled the Earth, along with a few farmers. Infectious and parasitic diseases were principal causes of human deaths, along with accidents and attacks by animals and other humans. |
|
|
Term
| What happens in Stage 2 in epidemiological transition? |
|
Definition
| This happens during Industrial revolutions, and/or medical revolutions and during high population rates. People crowd into cities. Diseases spreads easily. Cholera is an example. |

Term
| The Possible stage 5 of epidemiologic transition |
|
Definition
| Reemergence of infectious and parasitic diseases. Reasons: Evolution (natural selection would eventually create the Godly Germs). Poverty: (infectious and easily treated diseases in Developed countries, are common in LDCs.) 3. improved travel (easy transfer of new bacteria. Like H1N1. Transferred from Mexico to USA very quickly. Signs of Stage 5.) |
