Secondly, land tenure arrangements and the urbanisation of agricultural or collectively-owned land (ejido) have left a complex legacy for modern-day housing and urban development. Thirdly, Mexico has managed to address, to a large extent and with remarkable speed, the country’s quantitative housing gap and transition to more permanent housing for an increasing share of the population. Such a rapid expansion of the housing stock has been seen in only a few OECD countries. Fourthly, while public policy in other OECD countries has also tended, to varying extents, to favour home ownership in recent decades, Mexico, along with Italy and Spain, is unusual in focusing its social housing policies on home ownership. Finally, Mexico is now beginning to transition out of a long period in which housing policy has been set by an implementing body (INFONAVIT), housing and urban policy is now in the hands of an explicit policy-making body, SEDATU.
