Migration causes population size to change cyclically over time because the two components of migration vary with time.

There are 2 components of migration:

  1. Immigration: the number of individuals coming into a population from another place.
  2. Emigration: the number of individuals leaving a population to another place.

Hence, when the number of people coming into a population is more than the number of people leaving the population, the population size increases. On the other hand, when the number of people leaving a population exceeds the number of people coming in, the population size decreases.

Thus, migration causes population size to change cyclically because immigration and emigration rates vary with time.
