natural increase rate
(Aka NIR) The percentage growth of a population in a year, computed as the crude birth rate minus the crude death rate.
The number of years needed to double a population, assuming a constant rate of natural increase.
crude birth rate
(Aka CBR) The total number of live births in a year for every 1,000 people alive in the society.
crude death rate
(Aka CDR) The total number of deaths in a year for every 1,000 people alive in a society.
total fertility rate
(Aka TFR) The average number of children a woman will have throughout her childbearing years.
infant mortality rate
(Aka IMR) The total number of deaths in a year among infants under 1 year old for every 1,000 live births in a society.

The number of people under the age of 15 and over age 64 compared to the number of people active in the labor force.
The process of change in a society's population from a condition of high crude birth and death rates and low rate of natural increase to a condition of low crude and birth and death rates, low rate of natural increase, and a higher total population.
Still high CBR, rapidly declining CDR, and very high NIR. Stage in MDCs 200 years ago and LDCs 50 years ago. (Cape Verde)
