It has been argued that MigrationWatch's messages "can be taken advantage of by people with Islamophobia and prejudice". The accuracy of the group's research has also been questioned. David Robinson, Professor of Housing and Public Policy at Sheffield Hallam University, argues that the group's assertion that immigrants are placing strain on social housing lacks evidence. Economist Philippe Legrain has claimed that "MigrationWatch's xenophobic prejudice is causing it to twist the truth" about the impact of immigration on the employment prospects of British people.
