Massutmaning

Originally self-published[citation needed] in Swedish, the book has been translated to Norwegian, and into English, published by Palgrave Macmillan.

[1][2] The book consists of 20 chapters and describes the effects of migration to Sweden, starting in the 16th century but with a primary focus on the most recent waves of immigrants.

[3] The book is concluded with 25 constructive proposals to reverse the negative trends among them recruiting more migrants to emergency services, decreasing taxes for low-income earners and halting of unqualified and unskilled labour migration.

Dagens Nyheter called it a "thorough review of facts" giving "an instructive explanation of sophisticated statistical analyses", [5] Expressen called it a "solid and serious research review with honest intent", marred by a "conspiracy theory" about the media,[6] and Aftonbladet stated that it constituted a "solid basis for discussion", was an "impressive book", and deserved a gold star for its educational contribution.

Lindbeck called the critique "farfetched" and "emotional", and described the book as "the most complete compilation of information from many different sources of migration problems in Sweden", while Lindqvist stated that the charges by Lööf & Martinsson were baseless.
