nettofjöldaaukning

Nettofjöldaaukning is an Icelandic term that translates to "net population increase" or "net population growth" in English. It refers to the change in the total number of people in a specific geographic area over a given period, usually a year. This increase is the result of two primary factors: natural population change and net migration.

Natural population change is calculated by subtracting the number of deaths from the number of births within a population. If births exceed deaths, there is a natural increase. If deaths exceed births, there is a natural decrease. Net migration accounts for the difference between the number of people entering a region (immigration) and the number of people leaving a region (emigration). If more people immigrate than emigrate, there is a net inflow of migrants. If more people emigrate than immigrate, there is a net outflow.

The nettofjöldaaukning is therefore the sum of the natural population change and the net migration. A positive nettofjöldaaukning indicates that the population has grown, while a negative nettofjöldaaukning signifies a population decline. This metric is crucial for demographic analysis, urban planning, economic forecasting, and understanding societal trends. It helps governments and organizations assess the impact of various social and economic policies on population dynamics.
