Fluctuations in the size of a population are often difficult to measure
... Fluctuations in the size of a population are often difficult to measure directly but may be estimated by measuring the relative rates of birth, death, immigration, and emigration in a population. The number of deaths and emigrations over time will decrease a population’s size, and the number of birt ...
