| The formula that calculates population change. The formula finds the increase (or decrease) in a population. The formula is found by doing births minus deaths plus (or minus) net migration. This is important because it helps to determine which stage in the demographic transition model a country is in. |

| Diffusion of fertility control |
|
Definition
| The diffusion of fertility control is spread throughout the world. In the U.S it’s below 2.1 in much of Africa it is above 4, if South America is between 2 and 3, in Europe it is below 2.1, in China and Russia it is below 2.1, and in much of the Middle East it is above 4. This is important because its shows how many kids a mother is having thus helping to see where the countries are growing rapidly and where countries are leveling off. |

| Demographic Transition model |
|
Definition
| Has 5 steps. Stage 1 is low growth, Stage 2 is High Growth, Stage 3 is Moderate Growth, and Stage 4 is Low Growth and Stage 5 although not officially a stage is a possible stage that includes zero or negative population group. This is important because this is the way our country and others countries around the world are transformed from a less developed country to a more developed country. |

| (IMR) The annual number of deaths of infants under one year of age, compared with total live births. Its is expressed as the annual number of deaths among infants among infants per 1000 births rather than a percentage. This is important because it tell how developed a country is, if they have a high IMR they are an LDC and if it is low they are an MDC. |

| This is when the projection population show exponential growth; sometimes shape as a j-curve. This is important because if the population grows exponential our resource use will go up exponential and so will our use as well as a greater demand for food and more. |

Definition
| There are two useful ways to measure mortality; infant mortality rate and life expectancy. The IMR reflect a country’s health care system and life expectancy measures the average number of years a baby can expect to live. This is important because you can use a countries mortality rate to determine important features about a country. |
|

Term
|
Definition
| (Crude Birth Rate) This is the ratio of live births in an area to the population of that area; it is expressed as number of birth in year to every 1000 people alive in the society. This is important because it tells you the rate a country is having babies as well as how fast you can expect that population to grow. |

theory that builds upon Malthus’ thoughts on overpopulation. Takes into count two factors that Malthus did not: population growth in LDC’s, and outstripping of resources other than food
Recognizes that population growth in LDC’s is from the transfer of medical talents from MDC’s but not the wealth that would provide food and resources. |
