Population dynamics refers to the changes and variations in the population size, composition, and structure over time. These changes are influenced by various factors, including birth rates, death rates, immigration, and emigration. One of the key elements in population dynamics is migration, which can be both external (international) and internal (within the same country). Migration affects population health, influencing access to healthcare, disease transmission, and the overall wellbeing of individuals in different regions. This paper provides an overview of the concepts of population dynamics, the types of migration, factors determining migration, and the impacts of migration on population health.
