Following Romania's accession to the European Union (January 1, 2007), a number of social and demographic problems continued to persist and even amplify under various forms of manifestation. Contrary to the expectations of the population, poverty remained at a relatively constant level. At the time of EU accession, the relative poverty rate was 24.6%, and after a decade of European integration, the relative poverty rate was 23.7%. Romania remains one of the poorest EU member countries. This fact led to a massive migration of Romanians to the countries of the community area. In the year of EU accession, 544074 Romanians emigrated to Western Europe and North America. In 2017, a number of 219327 Romanians temporarily emigrated, and this trend will continue in the coming years. Over 85% of Romanian emigrants are economically active persons (aged 15-64) and are at risk of fertility. Migration is a strongly conditioned socio-economic phenomenon, poverty and low standard of living compared to the average level in EU-28 being among the determining causes of this socio-demographic phenomenon. Also, the external migration has as a consequence the depopulation (the decrease of the population number), the demographic aging and, last but not least, it generates a shortage of labor force. Currently, Romania is experiencing a crisis of the skilled worlkforce, even though the employment rate is about 60% of the people between the ages of 15 and 64. This paper aims to analyse from a statistical viewpoint the socio-demographic problems (poverty, external migration, decreasing birth rate, demographic aging, the crisis of workforce) that Romania faces after joining the European Union, using statistical data provided by National Institute of Statistics –Romania, Eurostat and other internatioanal official statistics providers.
