Black San Diego: Concentration and Share
In San Diego, 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 San Diego metro, Black residents number about 105,000 and form 8% of the population on the alone-or-in-combination count — against 6% 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 8%, it is the composition of every school, congregation, and customer base in the metro. Shares sustain institutions — media, congregations, businesses, and civic organizations — and they shape how a metro appears in every national table this atlas publishes. The San Diego figure also explains the metro's place in the movement plates: concentration is itself an attraction, drawing new residents toward an established community with its institutions already built.
In San Diego, that pattern is the plate's whole subject: the table below gives the published share and count, and the map shades the share. San Diego holds about 105,000 Black residents within the city — Black alone or in combination, roughly eight percent of its 1.39 million people — and about 190,000 across the metropolitan area. Read back against the table, the general pattern resolves into San Diego's particular numbers.
The distribution reads at state scale in San Diego, where the table's rows give the published count and the share the map draws. The community's geography is the southeast: the neighborhoods along and below Imperial Avenue and Euclid Avenue — Lincoln Park, Valencia Park, Oak Park, Emerald Hills, Skyline, Paradise Hills — the district the covenants and the freeway map assigned to Black San Diego and which Black San Diego made its own. That is what a benchmark is for in an atlas: not to rank San Diego, but to locate it.
Reading This Plate
The definitions differ by the multiracial population — a real and growing count, small against shares like San Diego's. The definitions differ by the multiracial population — small against shares of this size — and the ordering they produce is the finding. San Diego's place in that ordering is its concentration signature.
The distribution reads at state scale in San Diego, where the table's rows give the published count and the share the map draws. The employment file is written by the fleet: Naval Base San Diego and the region's defense economy employ Black San Diego directly (the enlisted and civilian workforces of the installations — the military profile's Pacific hub) and through the shipbuilding and repair yards (General Dynamics NASSCO and the waterfront contractors) whose wartime hiring built the community and whose modern workforce keeps its industrial tier. The benchmark's work is location, not rank: it fixes where San Diego stands so the plate can be read.
In San Diego, that pattern is the plate's whole subject: the table below gives the published share and count, and the map shades the share. The institutional layer: the churches of the southeast corridor, the San Diego Voice & Viewpoint (the Black newspaper), the Urban League of San Diego County, the NAACP branch whose school cases reached the state's courts, and San Diego State's Africana Studies (among the nation's first such departments, 1972) anchoring the academic file. Held against the national ladder, San Diego's own rows say where its attainment stands.
A note on this plate's figures, stated once and plainly: Black residents of the San Diego metro, alone or in combination: 105,000; Black share of the San Diego metro population, alone or in combination: 8%; Black share of the state population, alone: 6%. In San Diego, 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 San Diego are a reference, meant to be cited, compared, and returned to. In San Diego, 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.
