If natural increase is +1.6 percent and net out-migration is -1.6 percent, what is the total growth rate?

Answer and explanation

Correct answer: 0 percent

Total growth is the algebraic sum of natural increase and net migration. A positive natural increase adds population through births exceeding deaths. Net out-migration removes population, so it is represented by a negative rate. Equal positive and negative rates cancel each other when added.

The calculation is \(1.6+(-1.6)=0\) percent. Therefore, the total population has zero net growth, making option C correct. This does not mean that no births, deaths, or migration occur; it means their combined effect leaves the population numerically unchanged over the stated period. Adding the two magnitudes as 3.2 percent would ignore the negative sign of out-migration.
