Black Population in Mississippi: The Highest Share in America
What follows is the plate the atlas files as Black Population in Mississippi: The Highest Share in America. Its table records Black share of Mississippi's population — the highest of any state: 38%; residents of Jackson, the capital, who are Black — among the highest shares of any state capital: 4 in 5. In Mississippi, that is the whole of the plate's claim, and it is enough for a reference.
In Mississippi, read as a region, the pattern crosses the state borders the other plates observe, and the table below fixes its measures. The decennial census counted Black Mississippians at about 37 percent of the population Black alone, and about 38 percent Black alone or in combination — the highest share of any state, a position Mississippi has held throughout the modern census era. In absolute terms the population is about 1.1 million, modest beside the giants of this series; it is the share, and what the share has meant across Mississippi's history, that makes the profile central to this reference. Mississippi's own rows, tabled below, are where this general material becomes a specific place.
The Delta and the County Map
In Mississippi, this regional plate reads the same federal material at the scale of the region itself, and the table below carries its published measures. The Mississippi Delta — the flat alluvial plain in the state's northwest, among the richest farmland on earth — records the country's most extensive majority-Black rural geography: county after county above 60, 70, and in Holmes County's case around 80 percent Black. The county map of Black Mississippi is, with unusual literalness, a map of where enslaved labor was concentrated in 1860 — the demographic foundation on which everything else in the state's data rests. In Mississippi, general material earns its place in an atlas only when it sharpens the local record, which the table below states.
Jackson: A Black Capital City
For Mississippi, this regional plate reads the same federal material at the scale of the region itself, and the table below carries its published measures. In Mississippi, jackson, the capital and largest city, is more than four-fifths Black — among the highest Black shares of any American city of its size — making it one of the few state capitals where Black political and civic life is the civic mainstream. Here, on the plate for Mississippi, general material earns its place in an atlas only when it sharpens the local record, which the table below states.
The Weight of the Out-Migration
No state's Black population was more transformed by departure. Mississippi was the single greatest sending state of the Great Migration relative to its size: Chicago's Black population was built substantially by Mississippians, whose northward movement between the 1910s and the 1970s removed what demographers estimate as a majority of the state's young Black adults across two generations. The census record shows the residue in today's structure — an older age profile than the Southern average, counties whose populations have declined for decades, and a diaspora whose size rivals the home population: there are metropolitan areas of the North whose Mississippi-descended Black populations approach the Delta's own. Return migration exists in the Mississippi data but at smaller scale than in Georgia or Texas; the flows remain, on net, closer to balance than to reversal.
Composition and Conditions
Mississippi's Black indicators record the most difficult conditions in this reference on most measures, and the profile must state them plainly: the lowest Black median household income of any state in most survey years, among the highest Black poverty rates, and health indicators — in the data of the public health section — that include the nation's highest rates on several measures. Educational attainment has risen steadily, carried by Jackson State, Alcorn State, Mississippi Valley State, Tougaloo, and Rust — an unusually rich HBCU infrastructure for a state of three million — and by the community college system. The foreign-born share of Black Mississippi is among the nation's lowest: this is one of the most entirely native-born, deep-rooted Black populations in America, with family continuities in Delta counties extending to emancipation and beyond.
Reading the Mississippi Numbers
In Mississippi, the regional series holds its geography whole; the state plates elsewhere in the atlas divide the same ground by state lines. Mississippi teaches the series' most important distinction between share and scale in reverse: the highest share in the nation attached to a population of 1.1 million means that Mississippi's Black experience, however central to American history, is a small fraction of Black America's present numbers — while its conditions, at the hard end of nearly every distribution in this reference, define the floor against which national progress is measured. The general record matters here only as far as it sharpens the local one, which Mississippi's table states plainly.
