Swedish (Svenska) belongs to the East Scandinavian group of the Germanic branch of the Indo-European language family. It is primarily spoken in Sweden, but also spoken in Canada, Estonia, Finland, Norway, United Arab Emirates, and USA. The worldwide population of speakers of Swedish is estimated to be around 9.2 million people (Ethnologue).
Swedish is closely related to Norwegian and Danish. The three languages developed from Old Norse which was spoken in the areas of Scandinavia that are now Norway, Denmark and Sweden. To this day, Danes, Norwegians, and Swedes can talk to each other without an interpreter. Despite the high degree of mutual intelligibility it would not be correct to call the three languages dialects, because Danes, Norwegians, and Swedes see these languages as standardized official languages of their respective countries with separate norms for speaking and writing.
