traces the cyclical movement upwards and downwards in a graph. So named for its shape as the letter "s." Relates to growth and decline in the natural increase.
The number of males per 100 females in the population.
total fertility rate (TFR)
The average number of children a woman will have throughout her childbearing years.
zero population growth
A decline of the total fertility rate to the point where the natural increase rate equals zero
the spreading of people over an area of land
Between 30 N and 60 N and 30 S and 60 S; area where most people live
