| 36475110 | Child Mortality Rate | A figure that describes the number of children that die between the first and fifth years of their lives in a given population. | |
| 36475111 | Chronic Diseases | Generally long - lasting afflictions now more common because of higher life expectancies. | |

| 36475113 | Crude Death Rate (CDR) | The number of deaths yearly per 1,000 people in a population. | |
| 36475114 | Demographic equation | NIR = CBR - CDR | |
| 36475115 | Demographic momentum: | is the tendency for growing population to continue growing after a fertility decline because of their young age distribution. This is important because once this happens a country moves to a different stage in the demographic transition model. | |

| 36475135 | natality rate (NIR) | number of birth/ year to every 1000 people in the population | |
| 36475136 | Natural Increase | Population growth measured as the excess of live births over deaths; does not reflect either emigrant or immigrant movements. | |
| 36475137 | Natural increase rate (NIR) | CBR - CDR = NIR | |
| 36475138 | Neo-Malthusians | group who built on Malthus' theory and suggested that people wouldn't just starve for lack of food, but would have wars about food and other scarce resources. | |
