Sweden's position as one of the world's most highly developed post-industrial societies looks fundamentally secure.
Unemployment is low and the economy strong. Public-private partnership is at the core of "the Swedish model", which was developed by the Social Democrats, who governed for most of the 70 years up to 2006.
This mixed economy traditionally featured centralised wage negotiations and a heavily tax-subsidised social security network. The Swedes still enjoy an advanced welfare system, and their standard of living and life expectancy are among the highest in the world.
Relative to its population size, Sweden has taken in far more migrants than any other EU country since the beginning of the migration crisis in 2015. This has put pressure on public services, and prompted a surge in support for the far-right Sweden Democrats party.
King: Carl XVI Gustaf
King Carl XVI Gustaf ascended the throne in 1973, on the death of his grandfather Gustaf VI Adolf. The current king's father died in a plane crash in 1947, when Carl Gustav was only nine months old.
During his long royal apprenticeship, Carl Gustav underwent the usual military training, but also studied history, politics and economics at Swedish universities, served in the diplomatic corps, and worked in banking and commerce.
Constitutional changes in 1974 deprived the king of all but ceremonial duties, such as opening parliament and representing Sweden at the diplomatic level.
Prime minister (outgoing): Stefan Lofven
Former union boss Stefan Lofven formed a minority, centre-left coalition government made up of his Social Democrats and the Green Party.
He put together the coalition after parliamentary elections of September 2014, in which his party gained 31% of the votes and the Greens 7%.
He promised he would seek wide support for his plans to boost welfare, schools and jobs.
Elections in September 2018 produced a result that allowed neither the centre-left nor centre-right to form an immediate coalition. Parliament voted down Mr Lofven, and the speaker began the process of asking party leaders to try to form a new government.
Swedish audiences enjoy a wide variety of public and commercial broadcast services.
TV is the most-popular medium. Public Sveriges Television's (SVT) main competitor is commercial network TV4. Sweden is home to the regional media giants Bonnier and the Modern Times Group (MTG).
Most households have multichannel cable or satellite TV. Sweden has made the switch to digital terrestrial TV (DTT) and pay TV is broadcast in the format.
Public radio is run by Sveriges Radio. There are nearly 100 private radios; some are part of near-national networks.
