What are the factors affecting population growth ?
The birth and death rates of four countries are given below. Which one will have the least population growth rate?
$Country$ | $Birth\, rate$ $/1000$ | $Death$ $/1000$ |
$M$ | $15$ | $5$ |
$N$ | $25$ | $10$ |
$O$ | $35$ | $18$ |
$P$ | $48$ | $41$ |
Two opposite forces operate in the growth and development of every population. One of them related to the ability to reproduce at a given rate. The force opposite to it is called
