Metro Plates
Black Baltimore: Growth and Movement
In Baltimore, metros are where the national movement story is actually decided — the gains and losses of a few dozen large communities add up to the country's direction. This plate reads the movement record of Black Baltimore, a metro of about 850,000 Black residents, against the currents that have reshaped Black geography in the present era.
Growth and Movement
For Baltimore, the national movement figures are the current; the state's own distribution, tabled below, is where the current lands. 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. The comparison the plate invites is therefore two-sided: the national ladder on one side, Baltimore's attainment on the other.
The migration currents read locally in Baltimore, where the state rows below set the population whose movement the national pattern frames. As throughout this section, the metro tells a second story. A benchmark in an atlas does not rank Baltimore; it locates it, and that is its whole use here.
The Currents Around the Metro
In Baltimore, the present era's currents run in several directions at once: toward the South and its suburbs, out of the highest-cost coastal metros, and into mid-sized metros whose Black populations are growing fastest in percentage terms. The Baltimore metro's record, in the published counts, is its own negotiation among those currents. In Baltimore, each decennial census and each survey year revises the picture at the margin; the direction of the lines is the story, and this plate is built to be re-read as the lines extend.
The migration currents read locally in Baltimore, where the state rows below set the population whose movement the national pattern frames. 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. The general record matters here only as far as it sharpens the local one, which Baltimore's table states plainly.
Movement into and out of the Baltimore metro is measured in the federal record as the difference between counts, and its streams — births and deaths inside the metro, arrivals from other American places, arrivals from abroad — are published separately in the estimates program. In Baltimore, read together with the concentration plate, the movement record explains how the share above came to be, and where it is tending.
In Baltimore, that national movement pattern arrives as local gain or loss, and the table below fixes the population it describes. In Baltimore, the figures here are the published ones, rounded as the source agencies round them, and they describe the population as the federal record counts it: residents, in place, on the reference dates of the census and the survey. Against the table, the national pattern sharpens into the particular numbers of Baltimore.
The migration currents read locally in Baltimore, where the state rows below set the population whose movement the national pattern frames. Read this plate together with its companions. Not to rank Baltimore but to locate it — that, in an atlas, is the use of a benchmark.
In Baltimore, that national movement pattern arrives as local gain or loss, and the table below fixes the population it describes. In Baltimore, what the federal record cannot do is count a place's meaning — only its people. In Baltimore, general material earns its place in an atlas only when it sharpens the local record, which the table below states.
The atlas gives this subject its own plate — Black Baltimore: Growth and Movement — because the published record supports one. 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, the figures are the argument; the text only keeps them in order.

| Measure | Figure |
|---|---|
| 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% |
| Black share of the United States population, alone (population estimates) | 13.5% |

Method: Figures are drawn from the published federal sources named on this page, for the geography named; tile shading bands the published Black population share into the five legend classes. Counts are rounded as published by the source agency, and national benchmark rows are labeled with the basis they are published on.
