California vs Wyoming: 39 Million vs 587,000 — the Population Gap
California has 39,431,263 people. Wyoming has 587,618. That is not a gap — it is a different scale of country. California has about 67 times Wyoming’s people, and about 1 in 9 Americans lives in California alone. You could take Wyoming’s entire population, multiply it by 67, and you would only just reach California. This guide explains the gap in plain numbers, why California is so far ahead, why Texas and Florida combined beat California even though neither does alone, who sits at the bottom of the table, and how to remember the order — so the next time someone asks you to sort the states by population, you answer from the numbers, not from a guess.

The 67-Times Gap
The gap is a division problem: 39,431,263 divided by 587,618 is 67.1. That is the whole story in one number. California is the most populous state and Wyoming is the least, and the ratio between them is 67 to 1. Saying “about 67 times” is the safe way to remember it, because the exact figure, 67.1, is harder to hold in your head than the round claim, and the round claim is true. The gap is so big that it breaks intuition: most people guess California is ten or twenty times Wyoming, because twenty already sounds enormous. Sixty-seven sounds like a typo. It is not a typo. It is what happens when the biggest state by people is compared with the smallest, and the comparison is honest — one vintage, one date, 1 July 2024, from the same Census Bureau release, measured the same way.
| Rank | State | Population (1 Jul 2024) |
|---|---|---|
| 1 | California | 39,431,263 |
| 2 | Texas | 31,290,831 |
| 3 | Florida | 23,372,215 |
| 4 | New York | 19,867,248 |
| 5 | Pennsylvania | 13,078,751 |
| 46 | South Dakota | 924,669 |
| 47 | North Dakota | 796,568 |
| 48 | Alaska | 740,133 |
| 49 | Vermont | 648,493 |
| 50 | Wyoming | 587,618 |
Notice what the table does not do: it does not mix vintages. Every figure is the Census Vintage 2024 estimate for 1 July 2024, from the same release. That matters, because population figures change every year and each new release revises the old numbers — a figure from the Vintage 2025 release is a different answer, even for the same date. This guide uses one vintage throughout, and says so, so the order never changes on you mid-quiz.
One in Nine Americans
California’s share is as striking as the gap: 39,431,263 out of 340,110,988 Americans is 11.6%, about 1 in 9. Walk down a street with nine Americans on it and, on average, one of them lives in California. Texas is next at 31,290,831 and Florida third at 23,372,215, and the top three together hold more than a quarter of the country. That concentration is why California matters so much in national politics, national markets and national culture — and why the population quiz starts there. Learn the top three first, because they never move, and the rest of the table is a sorting problem around them.
Texas and Florida Combined Beat California
Here is the comparison that catches everybody: California is the biggest single state, but Texas and Florida combined have more people than California alone. Add them up — Texas 31,290,831 plus Florida 23,372,215 — and you get 54,663,046, against California’s 39,431,263. The gap is more than 15 million. That is the combined trap: “biggest state” and “most people” are not the same question when two states team up, and a quiz that asks “which has more people — California, or Texas and Florida combined?” is testing whether you add before you answer. The same trick works at the bottom: Wyoming, Vermont, Alaska, North Dakota and South Dakota combined have about 3.7 million people — fewer than many single cities.
The Smallest Five
At the bottom, the order is Wyoming 587,618, Vermont 648,493, Alaska 740,133, North Dakota 796,568 and South Dakota 924,669. Three of the five are northern plains and mountain states, and Alaska — the biggest state by area — is the third emptiest by people. The gaps at the bottom are small in absolute terms but huge in relative ones: Vermont has about 10% more people than Wyoming, and South Dakota has about 57% more than Wyoming. That is why the smallest-five questions feel harder than they look: the numbers are small, the gaps are proportionally big, and the order is easy to scramble. Learn them as a chain — Wyoming, Vermont, Alaska, North Dakota, South Dakota — and say the chain until it sticks.
How to Remember the Order
Do not try to memorise fifty numbers. Memorise two chains and two anchor facts. The top chain: California, Texas, Florida, New York, Pennsylvania — the five biggest, in order. The bottom chain: Wyoming, Vermont, Alaska, North Dakota, South Dakota — the five smallest, in order. The anchor facts: California is about 67 times Wyoming, and about 1 in 9 Americans lives in California. Then add the middle: Illinois, Ohio, Georgia, North Carolina, Michigan — ranks six to ten, all above ten million. Then play the quiz: twenty rounds, ten seconds each, and every miss comes back with the two figures side by side. One game a day is enough. The chains do not change, the figures do not change, and the second game is almost always better than the first, because the top five and the bottom five are already half-memorised by the time the timer runs out.
How many times bigger is California than Wyoming?
About 67 times — 39,431,263 divided by 587,618 is 67.1.
What share of Americans live in California?
About 1 in 9 — 11.6% of the 340,110,988 Americans.
Which state has more people: California, or Texas and Florida combined?
Texas and Florida combined — 54,663,046 against California’s 39,431,263.
Which vintage are the figures from?
Census Vintage 2024, 1 July 2024 — one vintage for every population question, so the order never changes mid-quiz.
One state, 39 million people. One state, 587,000. Sixty-seven times between them, and one American in nine living in the first. The order is the lesson: the biggest are the coastal giants, the smallest are the plains and the far north, and the gap is bigger than it looks. Test yourself on all of it now, top ten and bottom five included.
