| 4863717087 | population distribution | the arrangement or spread of people living in a given area; also, how the population of an area is arranged according to variables such as age, race, or sex | 3 | |
| 4863717629 | Dot Map | A dot distribution map (also known as dot density map) is a map type that uses a dot symbol to show the presence of a feature or phenomenon. Dot maps rely on a visual scatter to show spatial pattern. | 4 | |

| 4863731425 | Old-age dependency ratio | The dependency ratio is a measure showing the number of dependents, aged zero to 14 and over the age of 65, to the total population, aged 15 to 64. It is also referred to as the "total dependency ratio." | 8 | |
| 4863733689 | Child-dependency ratio | The dependency ratio is a measure showing the number of dependents, aged zero to 14 and over the age of 65, to the total population, aged 15 to 64. It is also referred to as the "total dependency ratio." | 9 | |
| 4863733690 | Doubling time | The period of time required for a quantity to double in size or value. It is applied to population growth | 10 | |

| 4863782582 | Zero population Growth | the maintenance of a population at a constant level by limiting the number of live births to only what is needed to replace the existing population. | 12 | |
| 4863784309 | Crude birth rate | The crude birth rate is the number of live births occurring among the population of a given geographical area during a given year, per 1,000 mid-year total population of the given geographical area during the same year. | 13 | |
| 4863784310 | crude death rate | The crude death rate is the number of deaths occurring among the population of a given geographical area during a given year, per 1,000 mid-year total population of the given geographical area during the same year. | 14 | |
| 4863787037 | natural increase | The difference between the number of live births and the number of deaths occurring in a year, divided by the mid-year population of that year, multiplied by a factor (usually 1,000). It is equal to the difference between the crude birth rate and the crude death rate. | 15 | |
| 4863787038 | demographic transition | the transition from high birth and death rates to lower birth and death rates as a country or region develops from a pre-industrial to an industrialized economic system. | 16 | |

| 4863794516 | Infant Mortality Rate | the number of deaths under one year of age occurring among the live births in a given geographical area during a given year, per 1,000 live births occurring among the population of the given geographical area during the same year. | 20 | |
| 4863794517 | Child Mortality Rate | also known as under-5 mortality or child death, refers to the death of infants and children under the age of five or between the age of one month to four years depending on the definition | 21 | |

| 4863891247 | Chronic Diseases | A chronic disease is one lasting 3 months or more, by the definition of the U.S. National Center for Health Statistics. Chronic diseases generally cannot be prevented by vaccines or cured by medication, nor do they just disappear. | 24 | |
| 4863900032 | Genetic disorder | A genetic disorder is a genetic problem caused by one or more abnormalities in the genome, especially a condition that is present from birth (congenital). Most genetic disorders are quite rare and affect one person in every several thousands or millions. | 25 | |
