Gypsy people are the most poorly considered minority in Spain. Their current circumstances in relation to growth rate and trend variation in this country are not well known. The main objective of this paper is to show what happens to a person's growth process in a transitional minority group affected by the process of globalisation. As target population and the articulation of social actions to have an implementation of quality of life is an additional objective. The research team, in collaboration (...) with “Apoyo”, an NGO, made contact with each Gypsy family. The sample comprised 189 boys aged 5 to 14 years. The boys and their families have been rehoused in two large buildings, named “Ruedo” and “Herradura”, in an attempt to accommodate the marginal Gypsy population following the disappearance of their shanties in Madrid. Morphological and physiological variables were considered as well as social situation and nutritional habits. Large family size (5–6 children), smoking and coffee- drinking habits and the intake of less than the internationally recommended number of calories after the age of 8 years endangers the healthy growth of these European Union citizens.
