Blacksburg is dominated economically and demographically by the presence of Virginia's largest university, Virginia Polytechnic Institute and State University (better known as Virginia Tech).
Geography\nBlacksburg is located at 37°13'48" North, 80°25'4" West (37.229874, -80.417694)1.

Blacksburg's age distribution is: 9.7% under the age of 18, 57.4% from 18 to 24, 18.9% from 25 to 44, 9.2% from 45 to 64, and 4.9% who are 65 years of age or older. The median age is 22 years. This unusual age distribution is explained by the presence of Virginia Tech, which heavily skews the population toward the 18-24 group. For every 100 females there are 127.0 males. For every 100 females age 18 and over, there are 129.7 males. Virginia Tech's presence also explains the unusual sex distribution; it has large and well-regarded programs in several male-dominated academic fields, most notably engineering.
The median income for a household in the town is $22,513, and the median income for a family is $51,810. Males have a median income of $37,129 versus $24,321 for females.

Out of the total people living in poverty, 23.7% are under the age of 18 and 6.1% are 65 or older. However, traditional measures of poverty can be highly misleading when applied to communities with large student populations, such as Blacksburg.
