“The immediate cause of the increase of population is the excess of the births above deaths; and the rate of increase, or the period of doubling, depends upon the proportion which the excess of the births above the deaths bears to the population.”

“Animals use aggression as a technique for gaining control over necessities… that are scarce or are likely to become so… They intensify their threats and attack with increasing frequency as the population around them grow. As a result the behavior itself induces members of the population to spread out in space, raises the death rate, and lowers the birth rate. In such cases aggression is said to be a "density-dependent factor" in controlling population growth.”

“Since 1965 […. ] the richest fifth of the world's population increased its average income by 75 percent. For the poorest fifth of the world's population, the increase has been faster still, with average incomes more than doubling during the same period.”

“If this were true, the population of the world would be at a stand-still. In truth, the rate of birth is slightly in excess of death. I would suggest that the next edition of your poem should read: “Every moment dies a man, every moment 1 1/16 is born.” Strictly speaking, the actual figure is so long I cannot get it into a line, but I believe the figure 1 1/16 will be sufficiently accurate for poetry.”

“Germany's population was increasing, her industries were intact, she had no factories to reconstruct, she had no flooded mines. Her resources were intact, above and below ground…In fifteen or twenty years Germany would be mistress of Europe. In front of her would be France with a population scarcely increased.”
