ABSTRACT
One of the gravest problems of our time is presented by uncontrolled human fertility. The world's population to-day is greater than it has ever been before; it has grown from about 540 millions in A.D. 1050 to more than 2·4 billions in 1951. And it is increasing by about 68,000 people every day, or about 25 millions a year, of which India alone contributes about five millions. At this current rate of increase of more than one percent per annum the population could multiply to 4·2 billions by A.D. 2000! Apart from the staggering total number and the incredible pace at which the world's population is growing, there are two other disturbing factors in world demography. One is the international unevenness of population distribution and the other is the unevenness in the growth of different national populations.
