The number of people entering a population through 'birth' or 'immigration' being equal to the number of people leaving it via 'emigration' or 'death' is called:
- APositive population growth
- BZero population growth
- CNegative population growth
- DRapid population growth

Zero population growth (ZPG) occurs when the crude birth rate plus immigration equals the crude death rate plus emigration, resulting in a stable population size with no net increases or decreases over time.
