arable land

Land suitable for agriculture.

physiological density

The number of people per unit of area of arable land, which is land suitable for agriculture.

agricultural density

The ratio of the number of farmers to the total amount of land suitable for agriculture.

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.

doubling time

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.

dependency ratio

The number of people under the age of 15 and over age 64 compared to the number of people active in the labor force.

demographic transition

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.

Stage 1

Very high CBR and CDR; low NIR. Stage during most of human history.

Stage 2

Still high CBR, rapidly declining CDR, and very high NIR. Stage in MDCs 200 years ago and LDCs 50 years ago. (Cape Verde)

Stage 3

Rapidly declining CBR, moderately declining CDR, moderate NIR. IN MDCs 100 years. (Chile)

Stage 4

Very low CBR; low, slightly increasing CDR; and 0 or negative NIR. In MDCs recently. (Denmark)
