Social mix policy normally leads to the gentrification of poor neighbourhoods, which is neither beneficial for their original residents nor urban diversity. Conversely, in search of a possible way to ease mounting pressure on stigmatized neighbourhoods the article aims to uncover the middle class's attitude towards the construction of buildings with cheap rentals, a precondition of social mix policy. To this end, an innovative digital survey was conducted in 2020 in two recently developed inner-city neighbourhoods in the mid-sized Swedish city of Västerås. First, drawing on earlier research, our data confirms that there is a statistically significant negative correlation between young middle-class families, on the one hand, and their willingness to share “their own backyard” with presumptive low-income newcomers, on the other. Second, the analysis brings to the fore the fact that attitudes to social mixing are not just dependent on gender, but even on why one wants to move. Third, the predominance of an apparent elitist conception of housing is challenged by female and older residents who seek diversity. In sum, the findings imply that socially mixing certain kinds of middle-class neighbourhoods is possible if politicians fulfil three preconditions.
