Mansfield Park is home to a large immigrant population. The initial settlement of the suburb coincided with a large wave of immigrants from Eastern Europe arriving in Australia, following the Second World War. Although most of their children have moved on, a large number of immigrant retirees still live in the area. This is reflected in the decline of students attending local primary schools, with 702 students attending Mansfield Park Primary School at its peak in 1966. Another wave of immigration occurred in the 1980s, when Vietnamese immigrants arrived after the Vietnam War. Currently September 2012, more than 50% of the population is from a non-English speaking background.
