A country records 3 million births, 1.7 million deaths, and net out-migration of 1.5 million. What is the total population change?

Answer and explanation

Correct answer: Decrease of 0.2 million

Population change is found by combining natural change with migration. Natural change means births minus deaths. Net out-migration is then subtracted because more people leave the country than enter it. Thus, both the size of the birth–death difference and the migration balance must be considered together.

The natural increase is \(3.0-1.7=1.3\) million, or 13 lakh. Net out-migration removes another 1.5 million, so the total change is \(1.3-1.5=-0.2\) million. The negative sign means a decline, equal to 2 lakh. Therefore, option A is correct. Option C ignores migration and gives only the natural increase.
