Metro Plates
Black Baltimore: Concentration and Share
Where the general meets the particular is the table of Baltimore; read the two together. In the Baltimore metro, Black residents number about 850,000 and form 60% of the population on the alone-or-in-combination count — against 31% 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 60%, it is the composition of every school, congregation, electorate-sized gathering, and customer base in the metro. In Baltimore, 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 Baltimore 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 Baltimore, the pattern is not background but subject; the state's own rows, tabled below, carry it. Baltimore is one of the few large American cities where Black residents are the majority — about three in five of its roughly 585,000 people — and they have been for half a century. The metropolitan area holds approximately 850,000 Black residents, extending from the city's rowhouse neighborhoods through Baltimore County's suburbs. Baltimore's own rows, tabled below, are where this general material becomes a specific place.
The distribution reads at state scale in Baltimore, where the table's rows give the published count and the share the map draws. The Great Migration added Southern arrivals to this foundation, and the city's Black share climbed steadily across the twentieth century as the white population suburbanized — past half in the 1970s, to its present level near three-fifths. That is what a benchmark is for in an atlas: not to rank Baltimore, but to locate it.
Reading This Plate
What separates the two definitions is the multiracial population — real, growing, and small against shares of the size recorded in Baltimore. The definitions differ by the multiracial population — a real and growing count, small against shares like Baltimore's. Baltimore's place in that ordering is its concentration signature.
In Baltimore, that pattern is the plate's whole subject: the table below gives the published share and count, and the map shades the share. As throughout this section, the metro tells a second story. Held against the national midpoint, Baltimore's own rows say how its households stand.
The distribution reads at state scale in Baltimore, where the table's rows give the published count and the share the map draws. Baltimore's Black institutional anchor is Morgan State University — Maryland's largest HBCU, a research university enrolling roughly nine thousand students and designated a site of national importance in Black higher education — together with Coppin State University in West Baltimore. The benchmark's work is location, not rank: it fixes where Baltimore stands so the plate can be read.
The gazetteer pages of this atlas gather the Baltimore file in one place — the metro plates, the state plates for its state, and the national plates that frame both. In Baltimore, concentration is the thread that runs through all of them: it is why this metro carries the weight it does in the national distribution, and why its movements, gains and losses alike, register in the national counts when they come.
A note on this plate's figures, stated once and plainly: Black residents of the Baltimore metro, alone or in combination: 850,000; Black share of the Baltimore metro population, alone or in combination: 60%; Black share of the state population, alone: 31%. In Baltimore, 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.
The record behind this plate of Baltimore is published, not estimated by this atlas: U.S. Census Bureau, 2020 Census; American Community Survey; Population Estimates Program. Where the table carries a national benchmark row for Baltimore, the row is labeled with the basis it is published on — the same measure, the same basis, two geographies.
