Metro Plates
Black Washington: Concentration and Share
In Washington, concentration is the metro question in its purest form: how much of a place is Black, and how that share compares with the state and the nation around it. In the Washington metro, Black residents number about 1.6 million and form 41% of the population on the alone-or-in-combination count — against 45% for the state as a whole on the alone count, and 13.5% for the United States.
The Share and What It Builds
A share is not a statistic in the abstract; at 41%, it is the composition of every school, congregation, electorate-sized gathering, and customer base in the metro. In Washington, shares at this level sustain institutions — media, congregations, businesses, and political organizations — that smaller shares cannot, and they shape how a metro appears in every national table this atlas publishes. The Washington figure also explains the metro's gravitational pull in the movement plates: concentration is itself an attraction, drawing new residents toward an established community with its institutions already built.
For Washington, DC, the pattern is not background but subject; the state's own rows, tabled below, carry it. The metropolitan area holds about 1.6 million Black residents — roughly one in four — while the District of Columbia itself, which was the first large American city to become majority Black, in the 1950s, now records a Black share of about 41 percent: still the highest of any major American city jurisdiction, but no longer a majority. Washington's own rows, tabled below, are where this general material becomes a specific place.
The distribution reads at state scale in Washington, DC, where the table's rows give the published count and the share the map draws. The District's Black share peaked at about 71 percent in 1970, the product of a century and a half of Black Washington — a free Black community predating the Civil War, a Reconstruction-era influx, Great Migration arrivals, and the mid-twentieth-century departure of White residents to the suburbs. From the 1990s onward, the direction reversed: the city's population grew for the first time in decades on an influx of younger, affluent, disproportionately White newcomers, while Black Washingtonians moved to the suburbs in large numbers — many priced out of neighborhoods their families had inhabited for generations. That is what a benchmark is for in an atlas: not to rank Washington, but to locate it.
Reading This Plate
Two kinds of firms fill the federal business counts: employer firms with payrolls, and nonemployer firms — the sole proprietors who are most of Black business by number, in Washington as nationally. The ownership world divides in two in the federal counts — employer firms carrying payrolls, and nonemployer firms, the sole proprietors who make up most of Black business by number. Washington's place in that ordering is its concentration signature.
The distribution reads at state scale in Washington, DC, where the table's rows give the published count and the share the map draws. The demographic counterpart of the District's decline is Prince George's County, Maryland, directly east of the city: a county of nearly a million people that is roughly two-thirds Black and records median household incomes for Black households among the highest of any large county in the nation. Locating Washington is the benchmark's purpose; ranking it is not.
The distribution reads at state scale in Washington, DC, where the table's rows give the published count and the share the map draws. Howard University, founded in 1867, anchors the region's Black institutional life as the nation's most comprehensive historically Black university. The point of the benchmark is position: where Washington stands, stated before anything is made of it.
A note on this plate's figures, stated once and plainly: Black residents of the Washington metro, alone or in combination: 1.6 million; Black share of the Washington metro population, alone or in combination: 41%; Black share of the state population, alone: 45%. In Washington, each figure is published by the source named below and rounded as published; the plate's map shades the Black share of the population on the same basis, so the table and the map can be read against each other without conversion.
Two further figures complete the plate's account of Washington, DC: Black share of the state population, alone: 45%; Black share of the United States population, alone (population estimates): 13.5%. For Washington, stated together with the measures above, they fix the population this plate describes — its size, its share, and its standing against the national record — and they are the figures the surrounding text interprets, neither rounded further nor carried beyond what the source publishes.
