Student enrollment for Georgia Southern University was 19,691 for the 2010-2011 academic year and more than half of those students are expected to remain in Statesboro this summer. According to Betsy Nolen, assistant director of communications at GSU, student enrollment will be around 10,000 for the summer semesters that began Monday. Although official numbers will not be released until after the summer B-term starts in late June, the university already has seen its summer numbers rise in previous years.
