The object of this article is to make some reflections about the 5th survey of street usage of Basque in the Northern Basque Country. Several data are examined, taking in account age groups, number of inhabitants per town, monologues. The street use of the language drops without stop, passing from 6,5 % in 1993 to 4,6 % in 2006. However, this continuing fall occurs only in the group of the adults and that of the old persons. On the contrary, in the groups of the children and of the young people the fall is more or less stopped now, although the use of the chidren drops again a little according to the last survey. The factor which stops this fall of the street use could be the school teaching of the language or, also, that a part of this generation would be more daring by using the language learned at school outside of it, taking the Basque language like symbol of identity and difference. It is observed that the percentages of the street use of the language and those of bilinguals follow a parallel way.
