This book contributes to the discussion about territorial inequalities. Taking the cases of Chile, Mexico and Peru, it presents new evidence about patterns of development in our societies, with a degree of spatial breakdown that was previously unavailable. The authors study both the outcomes of these differentiated development dynamics, in terms of poverty and vulnerability, and the opportunities that our children and young people face in defining their access to education, basic services or goods necessary for their personal growth. They also analyze how territory, compared with personal circumstances, becomes a key factor in differentiated access to opportunities. This work also shows that we are not experiencing a process of territorial convergence in these countries, which would allow us to aspire to civilized levels of social cohesion within a reasonable time frame. At the same time, however, the three countries studied show growing territorial segregation, where personal aspirations are increasingly limited by the place where one lives. If we add to this territorial segregation the weakness of governance institutions in many of our Latin American countries, it is easy to see that we face an explosive mixture.
