This book addresses the issues of social cohesion and territorial cohesion in Luxembourg. It consists of sixteen chapters, which cover a variety of themes: inequalities related to monetary issues (incomes, wages and wealth); inequalities in terms of other aspects of living conditions (employment, education, housing); and spatial inequalities (related to cross-border mobility, access to public facilities, cross-border governance). It was prepared by almost forty researchers from the Luxembourg-based CEPS/INSTEAD public research centre. One of its key interests and novelties is its multi-disciplinary approach – economics and econometrics, geography, sociology, psychology and history are mobilised. Even though its main focus is on the situation in Luxembourg, several chapters suggest various comparisons with a number of European Union countries.
