Porto’s Social Housing Observatory reports 28,180 residents living in 12,409 public dwellings, with an average rent of €77.06. The City Council has allocated roughly 300 social housing units per year over the past four years — about 2.4% of the existing stock annually (≈9.7% cumulatively over four years). The figures indicate relatively low subsidised rents and an average household size of around 2.27 residents per dwelling, but the modest annual allocation rate suggests limited turnover or expansion in supply relative to the size of the stock, with implications for waiting lists, affordability pressures, and future policy planning.
