A socially mixed population is a political ambition in Stockholm. By providing a mix of tenure alternatives throughout all neighbourhoods this objective could, at least partially, be fulfilled. Since current tenure proportions display a weak balance in many neighbourhoods it could be assumed that governing politiciansby primarily utilizing Stockholm's vast landownership and municipal housing developersattempt to bridge observed gaps. Distribution of new rental and ownership apartments in municipal land allocations should acknowledge the existing tenure composition in a neighbourhood. Methodically this article focuses on all (nearly 50,000) apartments channelled through Stockholm's land allocation system between 2002 and 2012. After classification of all apartments based on tenure, location, year and developer (private or municipal) the information is merged with yearly housing stock characteristics for 128 neighbourhoods. The outcome is a unique data set allowing for statistical assessment of whether Stockholm's tenure (and in extension social) mix ambition is reflected in practice. The present article aims to highlight the crucial importance of landownership in Swedish municipalities with an aspiration to achieve or maintain a balanced tenure mix. While the findings indicate Stockholm is complying fairly well with its ambition, the results do reveal some contradicting signs.
