It has the biggest rentable facility in northern Europe called Stockholm International Fairs, and also the hotel Scandic Talk Hotel, which both are located east of Älvsjö commuter train station. In 2017, the total population of the district was 1,530 inhabitants.

The name was written Elffuesio in 1461. The origin of the first element is unclear – it is possibly derived from an Old Swedish male name *Ælve, but that interpretation is uncertain. The last element sjö 'lake' refers to Brännkyrkasjön, a former lake east of Älvsjö.
