If a country's birth rate is 20 per thousand and death rate is 20 per thousand with no migration, what will be the population situation?

Answer and explanation

Correct answer: Naturally stable

Natural increase is the difference between the birth rate and the death rate. When both rates are 20 per thousand, the difference is zero. If there is also no migration, no additional people enter or leave the country through migration. Therefore, the total population is naturally stable in the sense of no net numerical change, so choice B is correct.

Calculate natural increase as \(20-20=0\) per thousand. Net migration is also zero, so total change is approximately zero. This does not mean that no births or deaths occur; it means their numbers balance each other. The population could still change in age structure or location, but the total number remains roughly constant. Rapid growth, rapid decline, and doubling are not supported by equal birth and death rates.
