Metro Plates
Black Houston: Concentration and Share
In Houston, 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 Houston metro, Black residents number about 1.3 million and form 22% of the population on the alone-or-in-combination count — against 13% 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 22%, it is the composition of every school, congregation, electorate-sized gathering, and customer base in the metro. In Houston, 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 Houston 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.
The distribution reads at state scale in Houston, where the table's rows give the published count and the share the map draws. Houston holds the largest Black population of any city in Texas and one of the largest in the South: the metropolitan area counts about 1.3 million Black residents, and the city of Houston itself about half a million — roughly one in five Houstonians. That is what a benchmark is for in an atlas: not to rank Houston, but to locate it.
For Houston, the pattern is not background but subject; the state's own rows, tabled below, carry it. Houston's Black geography was organized by its ward system. Houston's own rows, tabled below, are where this general material becomes a specific place.
Reading This Plate
What separates the two definitions is the multiracial population — real, growing, and small against shares of the size recorded in Houston. The definitions differ by the multiracial population — a real and growing count, small against shares like Houston's. Houston's place in that ordering is its concentration signature.
The distribution reads at state scale in Houston, where the table's rows give the published count and the share the map draws. The metro's Black growth comes from three sources the migration data distinguish: natural increase in a comparatively young population; domestic in-migration, including a notable and lasting movement from Louisiana that accelerated after Hurricane Katrina displaced New Orleanians in 2005, many of whom remained; and international immigration. A benchmark in an atlas does not rank Houston; it locates it, and that is its whole use here.
In Houston, that pattern is the plate's whole subject: the table below gives the published share and count, and the map shades the share. Houston is one of the principal gateways of African immigration to the United States. Held against the national midpoint, Houston's own rows say how its households stand.
The gazetteer pages of this atlas gather the Houston file in one place — the metro plates, the state plates for its state, and the national plates that frame both. In Houston, 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 Houston metro, alone or in combination: 1.3 million; Black share of the Houston metro population, alone or in combination: 22%; Black share of the state population, alone: 13%. In Houston, 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.
How this plate is read, for Houston: 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 Houston metro, alone or in combination: 1.3 million; Black share of the Houston metro population, alone or in combination: 22%. In Houston, 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.

|---|---|
| Black residents of the Houston metro, alone or in combination | 1.3 million |
| Black share of the Houston metro population, alone or in combination | 22% |

| Black share of the United States population, alone (population estimates) | 13.5% |
Source: U.S. Census Bureau, 2020 Census; American Community Survey; Population Estimates Program. 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.
