Part I consists primarily of desktop studies. Chapter 1 is a literature review. Chapter 2 analyses segregation research publications, policy papers and news articles (particularly Finland's largest newspaper Helsingin Sanomat) between the years 1999 and 2015. The primary data used for the studies at the core of this book consist of interviews with representatives of state and municipal land and housing policy authorities in Finland. A total of 25 interviews in ten cities were conducted between 2013 and 2015 for a research project entitled Land Policy and Property Rights. The project was funded by the Academy of Finland, coordinated by Professor Anne Haila, and carried out at the University of Helsinki. The interviews were conducted to investigate what type of land policy is practised in cities, the goals and means of the land policy, and how various institutional changes have affected these goals and means; Chapter 4 is largely based on this study. The interviewed officials were chiefs of municipal real estate management, chiefs of municipal housing departments, and the cities’ mayors or vice mayors. The interviewees were chosen to enable the comparison of different types of cities, such as cities that had large land banks and cities that did not, old cities and new cities, growing cities and dying industrial cities. The interviewees represent people with a long professional history of decision-making regarding municipal land policy and who are experts in their field. In the interviews, land policy authorities expressed their arguments in favour of chosen land use objectives and land management strategies.
