  In this paper we take into account both social and linguistic aspects to
perform demographic analysis by processing a large amount of tweets in Basque
language. The study of demographic characteristics and social relationships are
approached by applying machine learning and modern deep-learning Natural
Language Processing (NLP) techniques, combining social sciences with automatic
text processing. More specifically, our main objective is to combine
demographic inference and social analysis in order to detect young Basque
Twitter users and to identify the communities that arise from their
relationships or shared content. This social and demographic analysis will be
entirely based on the~automatically collected tweets using NLP to convert
unstructured textual information into interpretable knowledge.
