You would think that the job market in a major metropolitan city like Washington, D.C., would be nothing short of booming. Surprisingly, though, its more residential neighbor of Northern Virginia has even more economic growth than the capital.

This region, often referred to as NOVA, has a notably strong economy and job market in the sectors of technology, health care, and consumer services, especially. According to a report published by the Fuller Institute, Northern Virginia gained three times as many jobs as Washington in 2018.

The future is looking bright for this cluster of East Coast towns. No longer is it just a place for Washington commuters to rest their heads; it's now a promising place to seek employment.

Northern Virginia's largest employers are a mix of private companies, universities, federal agencies, and military installations offering positions in tech, engineering, financial services, and health care.
