Metro Plates
Black Boston: Roxbury, Mattapan, and the Suburban Shift
This metro plate opens the Atlasmont file on Black Boston: the population itself — its size, its share of the metro, and its distribution across the city and suburbs that make up the metropolitan whole.
In Boston, the distribution reads at state scale in Boston, where the table's rows give the published count and the share the map draws. Boston holds about 160,000 Black residents within the city — Black alone or in combination, roughly a quarter of its people — and close to half a million across the metropolitan area, about a tenth of the region. The general record matters here only as far as it sharpens the local one, which Boston's table states plainly.
The Historic Core: Roxbury, Dorchester, Mattapan
Filed in this series as Black Boston: Roxbury, Mattapan, and the Suburban Shift, the plate below states the published record for its subject and reads it closely. Its table records Black residents of the City of Boston, approximately: 160,000; Black residents of the Boston metropolitan area: Near 500,000. In Boston, a reader who holds the table and this text together has the plate entire.
The Caribbean Metropolis
For Boston, the distribution reads at state scale in Boston, where the table's rows give the published count and the share the map draws. In Boston, greater Boston's Black population is, by the birthplace data, among the most immigrant of any in this section. A benchmark in an atlas does not rank Boston; it locates it, and that is its whole use here.
The Suburban Ring: Brockton, Randolph, and Beyond
In Boston, in Boston, that pattern is the plate's whole subject: the table below gives the published share and count, and the map shades the share. Stoughton, Milton, Quincy, and the Route 128 belt add growing communities, while Cambridge and Somerville hold smaller, older Black populations under severe housing-cost pressure — the tract data show declining Black counts in the inner core even as the metro total rises, Boston's version of the displacement arithmetic. Held against the national midpoint, Boston's own rows say how its households stand.
Institutions and Indicators
Black Boston's institutional layer runs through Roxbury Community College, the region's universities' Black enrollment (with no HBCU in New England, a structural absence the education data note), the hospital systems of the Longwood and Dorchester medical corridors — among the largest employers of Black Bostonians — and the state government. The indicators present the region's paradox: Massachusetts records among the nation's strongest Black educational attainment and health outcomes in the state rankings, and Boston's Black median income runs above most Northern peer metros', while its Black-white wealth gap — measured in a famous Federal Reserve study of the Boston metro at a median net worth difference among the most extreme ever published — cautions that income and wealth are different datasets, a lesson the census section's wealth tables generalize.
Reading the Boston Numbers
Boston is the Northern profile in which composition does the most work: abolitionist roots, Great Migration increments, and the North's fullest Caribbean layering in one population of half a million. Its state has no HBCU and no Black-majority city; its Black community is a quarter of its capital and a tenth of its region — and by attainment and health measures, among the strongest-positioned in this reference, against a wealth distribution that tells a different story underneath.
A note on this plate's figures, stated once and plainly: Black residents of the City of Boston, approximately: 160,000; Black residents of the Boston metropolitan area: Near 500,000. For Boston, 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.
A closing word on the use of this plate: the figures for Boston are a reference, meant to be cited, compared, and returned to. Every figure here descends from the published tables of the source named below, unaltered except by that source's own rounding; the counts themselves are there for the reader who needs them.
How this plate is read, for Boston: begin with the map, whose shading bands the published Black share into the legend's five classes, then turn to the table, which states the measures in figures — Black residents of the City of Boston, approximately: 160,000; Black residents of the Boston metropolitan area: Near 500,000. In Boston, the two presentations are one record in two forms, and a reader who checks one against the other has the plate's whole method in hand.
| Measure | Figure |
