The Massachusetts Income Plate
In Massachusetts, income is where the atlas's population counts meet household economics. This plate places Black Massachusetts in the national income geography: the benchmarks below are the published national figures for Black households, and Massachusetts's own distribution figures — 630,000 Black residents, 8 percent of the state — give the scale of the community those national patterns describe within the state's borders.
The National Pattern
For Massachusetts, the national benchmark is a yardstick, not a description; the description is the state's own distribution, tabled below. Median household income is the most widely used single measure of a population's economic position, and for Black households in the United States the Census Bureau's annual income report places the figure at $56,490. The plate sets the national midpoint beside Massachusetts's households and invites the two-sided reading.
For Massachusetts, the national benchmark is a yardstick, not a description; the description is the state's own distribution, tabled below. Household income counts the combined money income of everyone aged 15 and over living in the home — wages, salaries, self-employment income, Social Security, pensions, interest, and cash benefits — before taxes. On one side the national midpoint, on the other the households of Massachusetts — that is the comparison this plate invites.
In Massachusetts, that national income pattern is read against the state's own households, whose published share and count stand in the table below. The national median household income in the same report is $77,719. Against that benchmark, the Black median of $56,490 is about 73 cents on the dollar. Held against the national midpoint, Massachusetts's own rows say how its households stand.
Reading This Plate
How to read this plate: the state rows are the published census figures for Massachusetts; the benchmark rows are the published national figures, labeled as benchmarks. In Massachusetts, the plate makes no state income estimate of its own — it sets the state's population, counted exactly, beside the national income record, measured exactly, which is the honest first step of any income geography.
The Population Behind the Plate
In Massachusetts, that national income pattern is read against the state's own households, whose published share and count stand in the table below. Massachusetts holds about 630,000 Black residents — Black alone or in combination — roughly one in eleven of its people, with Black alone at about 452,000, or 6.4 percent. Read back against the table, the general pattern resolves into Massachusetts's particular numbers.
The income figures take their local meaning in Massachusetts, where the table's state rows set the population this benchmark describes. The African Meeting House on Beacon Hill (1806) is the oldest surviving Black church building in the country; the Abiel Smith School (1835) was among the first public schools built for Black children; the 54th Massachusetts Regiment's assault on Fort Wagner is the Civil War's most famous Black military episode; and Boston's abolitionist organizations — the Massachusetts Anti-Slavery Society, the Vigilance Committee's Underground Railroad work — were the movement's institutional core. An atlas benchmark earns its place by locating Massachusetts, never by ranking it.
Residents moving between states — domestic migration — are the stream that built and rebuilt Black geographies across a century and a half, Massachusetts's among them. Read against the population counted on the distribution plate, the national median describes the economic center of gravity of the community that Massachusetts's 630,000 Black residents belong to. Holding the structure still while the numbers move is the gazetteer's work — the only way an atlas stays honest across editions, for Massachusetts as for every entry.
For The Massachusetts Income Plate, the method is the atlas's own: named sources, published figures, and a table that carries what the map cannot. A note on this plate's figures, stated once and plainly: Black share of the state population (alone): 8%; Black share, alone or in combination: 9%; Black residents, alone or in combination: 630,000. In Massachusetts, the figures are the argument; the text only keeps them in order.
A closing word on the use of this plate: the figures for Massachusetts are a reference, meant to be cited, compared, and returned to. In Massachusetts, a reader who needs the underlying counts will find them in the published tables of the source named below, from which every figure here descends without alteration beyond the rounding the source itself applies.
Filed in this series as The Massachusetts Income Plate, the plate below states the published record for its subject and reads it closely. How this plate is read, for Massachusetts: 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 share of the state population (alone): 8%; Black share, alone or in combination: 9%. For Massachusetts, a reader who holds the table and this text together has the plate entire.
