The demographic profile of Sweden has altered considerably due to immigration patterns since the 1970s. As of 2017, Statistics Sweden reported that around 2,439,007 or 24.1% of the inhabitants of Sweden were from a foreign background: that is, each such person either had been born abroad or had been born in Sweden to two parents who themselves had both been born abroad. Also taking into account people with only one parent born abroad, this number increases to almost a third in 2017.
