There are no neighborhoods or neighborhood boundaries that the D.C. Government officially defines, so there are varying definitions of which areas constitute Downtown D.C. or the central business district of D.C.
The Washington Post in 2014 referred to "downtown" as the areas covered by two business improvement districts (BIDs):
DowntownDC (the historic central business east of the White House) and
Golden Triangle (areas which have more recently been regarded as part of the CBD, west of the White House).

Together, they form a diamond-shaped area stretching from Union Station, south to the National Mall, northwest past the White House to Washington Circle in Foggy Bottom and northeast to DuPont Circle.
