By the Numbers

By: Mary Clare Glover

The Washington Business Journal just published its annual Book of Lists, which ranks everything from the region’s public and private companies to malls, shopping centers, hospitals, and law firms. We flipped through the 200-page volume and picked out some fun facts: 

• Ranked by average weekday ridership, the busiest Metro stop is Union Station, which draws 34,383 riders a day. Union Station was followed closely by Metro Center, Farragut North, Gallery Place, and Dupont Circle. It’s no wonder the red line is always so packed.

• St. Albans School has the most expensive tuition among Washington-area private day schools: $31, 428. Rounding out the top five were Middleburg’s Foxcroft School ($30,712), Potomac’s St. Andrew’s Episcopal School ($29,690), DC’s National Cathedral School ($28,905), and The Bullis School in Potomac ($28,430).

• The biggest new residential construction project is Ashburn’s Loudoun Station Condominiums, which has a whopping 1,738 units.

• Using a system that factors in household income, home values, and net worth, WBJ ranked the 50 wealthiest zip codes in the region—and Northern Virginia swept the top five. Number one was Greenway, Virginia (22067), where the median household income is $213,244, the median home value is $1 million, and the median disposable income is $158,466. Great Falls (22066), Fairfax Station (22039), McLean (22101), and Vienna (22182) were right on Greenway’s heels.
