The main way into Harrisonburg is via I-81.
As of the 2010 census, the population was 48,914, with a census-estimated 2016 population of 53,078. The Bureau of Economic Analysis combines the city of Harrisonburg with Rockingham County for statistical purposes into the Harrisonburg, Virginia Metropolitan Statistical Area, which has a 2011 estimated population of 126,562. Harrisonburg is home to James Madison University (JMU), a public research university with an enrollment of over 20,000 students, and Eastern Mennonite University (EMU), a private, Mennonite-affiliated liberal arts university. Although the city has no historical association with President James Madison, JMU was nonetheless named in his honor as Madison College in 1938 and renamed as James Madison University in 1977. EMU largely owes it existence to the sizable Mennonite population in the Shenandoah Valley, to which many Pennsylvania Dutch settlers arrived beginning in the mid-18th century in search of rich, unsettled farmland. The city has become a bastion of ethnic and linguistic diversity in recent years.
