A state shaped by cotton and conflict, it lost hundreds of thousands to the Great Migration north between 1910 and 1970 as mechanisation and racial violence drove people away.
Every arrival has a beginning
The shifting face of the United States
A country in motion
Alabama
Alaska
Admitted to the union in 1959, it remains the least densely populated state despite sitting on a third of America’s total land area and some of its richest natural resources.
Arizona
Few states have grown faster. The population has doubled three times since 1950, driven by air conditioning, retirement migration, and the Sun Belt boom.
Arkansas
Among the few states to actually lose population in the twentieth century, mechanisation displaced sharecroppers and the Great Migration drew Black Americans north.
California
Home to one in eight Americans, it has been the most populous state since 1964, with an economy larger than that of most countries.
Colorado
Transformed by the gold rush of 1859, it has since reinvented itself through ranching, aerospace, and technology, becoming one of the fastest growing states of the twenty-first century.
Connecticut
The third smallest state by area, it punched well above its weight for two centuries as a manufacturing powerhouse before deindustrialisation reshaped its economy from the 1970s onwards.
Delaware
The first state to ratify the Constitution in 1787, its tiny size belies its outsized influence — more than half of all US publicly traded companies are incorporated here.
Florida
Barely populated until air conditioning arrived, it has added more people than almost any other state since 1950 and is now the third most populous in the nation.
Georgia
Atlanta’s rise as a regional powerhouse transformed the state’s fortunes. Growth was steady through the twentieth century before accelerating sharply as the Sun Belt drew migrants from across the country.
Hawaii
The most geographically isolated state in the union, it was the last to join in 1959 and remains the only state where Asian Americans form the largest ethnic group.
Idaho
Long one of America’s least populated states, it has seen extraordinary growth since 2000 as remote workers, retirees, and technology companies relocated from the Pacific Coast in search of more space and lower costs.
Illinois
Chicago made it the dominant Midwestern state for over a century, but population has stalled since the 1970s as manufacturing declined and residents moved south and west.
Indiana
A manufacturing heartland that rose with the automobile industry and fell with it, its population has grown modestly but steadily while neighbouring states declined.
Iowa
Its population peaked relative to the nation in the 1880s at the height of the agricultural frontier, and has grown slowly ever since as farming became mechanised and rural communities shrank.
Kansas
A wheat state at the heart of the Great Plains, it reached its population peak relative to the nation around 1900 and has grown slowly since as agricultural mechanisation emptied the rural landscape.
Kentucky
Settled early through the Cumberland Gap, it was among the most populous states in the union by 1800 but has fallen steadily in relative terms as industrialisation bypassed much of Appalachia.
Louisiana
Built on the Mississippi and shaped by French and Spanish colonial heritage, its population growth has been consistently interrupted by hurricanes, flooding, and economic volatility.
Maine
The northernmost state in the contiguous US, it has been losing young people to southern and western states for decades and is now among the oldest populations in the nation.
Maryland
Its proximity to Washington DC has driven steady growth since the mid-twentieth century, transforming it from a tobacco and shipping economy into one of the wealthiest states in the union.
Massachusetts
The cradle of American independence, it was among the most populous states at the founding but has been slowly outpaced as the centre of gravity shifted west and south.
Michigan
Built on the automobile, it boomed through the mid-twentieth century before deindustrialisation hollowed out Detroit and triggered one of the steepest population declines of any major state.
Minnesota
Settled largely by Scandinavian and German immigrants in the nineteenth century, it has maintained steady growth and consistently punches above its weight in quality of life rankings.
Mississippi
Long the poorest state in the union, it lost more of its population to the Great Migration than almost any other state as Black Americans moved north in search of opportunity and safety.
Missouri
Gateway to the west and home to two great river cities, its population has grown steadily but its share of national population has fallen as faster-growing states overtook it.
Montana
Vast in area but sparse in people, it has never held more than a sliver of national population and remains one of the least densely populated states despite steady growth since statehood.
Nebraska
Settled in the great homesteading era of the 1860s and 1870s, its population grew rapidly then plateaued as mechanisation reduced the labour needed to farm the Great Plains.
Nevada
The most dramatic growth story of the twentieth century. Barely inhabited until the mid-1900s, it has grown faster than almost any other state driven by Las Vegas, legalized gambling, and migration from California.
New Hampshire
Small, prosperous, and politically influential far beyond its size, it has grown steadily as a destination for those priced out of Massachusetts while retaining its reputation for independence.
New Jersey
The most densely populated state in the union, its proximity to both New York and Philadelphia has made it a permanent magnet for arrivals and one of the wealthiest states per capita.
New Mexico
Among the oldest settled territories in North America, Spanish colonists arrived centuries before American statehood in 1912, giving it a cultural continuity that few states can match.
New York
The dominant state for most of American history, it held more than 10% of the national population for over a century before being overtaken by California in the 1960s.
North Carolina
Long a quietly growing state, it has emerged as one of the most dynamic economies in the country since the 1990s driven by technology, finance, and migration from the north.
North Dakota
The least visited state in the union, its population has barely changed in a century despite an oil boom that briefly made it the fastest growing state in the early 2010s.
Ohio
The heart of industrial America for over a century, it has struggled since the 1970s as manufacturing left and its share of national population fell steadily.
Oklahoma
Born from the land runs of 1889, it grew rapidly in the early twentieth century before the Dust Bowl of the 1930s drove hundreds of thousands west in one of the largest mass migrations in American history.
Oregon
Long a destination for those seeking a fresh start, it has grown steadily since the mid-twentieth century and become a magnet for young professionals and technology workers moving north from California.
Pennsylvania
The second most populous state at the founding, it powered the industrial revolution through steel and coal before decades of deindustrialisation eroded its national standing.
Rhode Island
The smallest state by area, it was a significant commercial and industrial force in the nineteenth century but has grown barely at all in relative terms since the early 1900s.
South Carolina
The site of the first shots of the Civil War, it spent much of the twentieth century losing population to northern cities before reversing course as the Sun Belt drew retirees and manufacturers south.
South Dakota
Carved out of Dakota Territory in 1889 alongside its northern twin, it has remained one of the least populous states, its economy built on agriculture, tourism around Mount Rushmore, and the Badlands.
Tennessee
A state of contradictions, it gave the world country music and the atomic bomb, and has grown steadily as Nashville transformed from a regional city into one of the fastest growing metros in the country.
Texas
The second largest state by both area and population, its growth since the mid-twentieth century has been relentless, driven by oil, technology, and one of the highest rates of domestic and international migration in the union.
Utah
One of the fastest growing states of the past three decades, its combination of a young Mormon population, a booming technology sector, and dramatic landscape has made it a destination unlike any other.
Vermont
The least populous state in the contiguous US, it has changed little in population terms for two centuries, its small size and rural character making it resistant to the growth pressures that transformed neighbouring states.
Virginia
The birthplace of eight US presidents and the heart of the Confederacy, it has been transformed in recent decades by the growth of Washington DC’s suburbs into one of the wealthiest and most educated states in the union.
Washington
Named after the first president but shaped by the last century, it has grown dramatically since the rise of Boeing, Microsoft, and Amazon turned Seattle into one of the great technology cities of the world.
West Virginia
The only state created by seceding from another state during the Civil War, it has been in slow demographic decline for decades as coal collapsed and young people left for opportunities elsewhere.
Wisconsin
A state defined by dairy farming, progressive politics, and German immigrant heritage, it has grown modestly and consistently without ever dramatically gaining or losing its share of the national population.
Wyoming
The least populous state in the union and the last of the contiguous 48 to be settled, it has changed little in a century, its vast landscape home to fewer people than many mid-sized cities.

About the data
Each dot in the population chart represents roughly 100,000 people. Pre-contact indigenous figures are scholarly estimates, not Census data: Thornton (1987) puts the indigenous population within US territory at around 600,000 by 1790, excluded from the official Census count that year. The 1492 figure of approximately 5 million reflects Thornton’s estimate for the contiguous United States. Published scholarly estimates for the same territory range from under 2 million to over 10 million depending on methodology, and this remains one of the most contested questions in historical demography.
The state charts track each state’s share of national population over time, all on a shared scale. That scale is set by the highest point any state ever reached, which was Virginia at close to 19% of the national population in 1790. The dotted line marks 2%, the share each state would hold if population were split evenly across all 50.
The demographic breakdown uses the same six categories across four time periods, but the underlying data is not consistent. Census classification changed a lot over that span. Hispanic was not tracked as its own category until 1980, and indigenous populations were left out of early counts entirely. Where Census data does not exist or is incomplete, the figures are scholarly estimates instead. The population chart uses a square root scale in growth view, so column widths reflect relative population size while keeping earlier years legible alongside the modern figures.
