If natural increase is +1.3 percent and net out-migration is -1.3 percent, what is the total growth rate?

Answer and explanation

Correct answer: 0 percent

Total population growth combines natural increase with net migration. Natural increase is positive 1.3 percent, while net out-migration is negative 1.3 percent. Because the two percentages have equal size and opposite signs, the loss through migration exactly offsets the increase from births minus deaths.

The calculation is \(1.3+(-1.3)=0\) percent. Therefore, option C is correct. This means the total population may remain numerically stable during the period. It does not mean that no births, deaths, or movements occur; it means their combined effect is zero. The positive and negative components must be added with their signs, not treated as two positive increases.
