Demography is important when you aim to understand the future. Today’s trend toward a growing and ageing population is very much an issue for the future as it affects not only the individual but many parts of society. It is, e.g., of great importance for how we organize labor and welfare.
How we relate to each other in a population is also changing due to demographic development. By understanding people’s personal networks, we can study the spread of crime, for example. Personal networks and relationships have also proven to be very important for our health, and this information could be used in preventive work against the spread of illness.
In recent years, new forms of relationships have emerged. Does this mean that our need for close relationships has changed or that it is just taking on new forms? What are the consequences for how we live, work, and have children?
