It’s a question that pops up more often than you’d think: Are there 50 states or 52? The answer is straightforward—50—but the confusion often comes from how we talk about territories and the order in which states joined the Union. This article clears up the state count, names the oldest and least populated states, and puts the numbers in context with official data.
Number of States: 50 ·
Oldest US State: Delaware (ratified Constitution 1787) ·
Least Populated US State: Wyoming (approx. 576,851)
Quick snapshot
- 50 states in the Union (Wikipedia)
- Oldest state: Delaware (1787) (USAFacts)
- Least populated state: Wyoming (U.S. Census Bureau)
- Largest state by area: Alaska (U.S. Census Bureau)
- 2025 population estimates will reaffirm Wyoming as least populated (NCHStats)
- Median age shifts may push a new state to “oldest by age” title (World Population Review)
Seven facts stand out when you look at the Union’s structure—ranging from the number of states to the striking gap in age between the first state and the rest.

| Youngest US State | Hawaii (1959) | USAFacts |

| Least Densely Populated | Alaska (1.3/sq mi) | U.S. Census Bureau |

The pattern: one metric—”oldest state”—can mean three different things depending on whether you measure admission date, median age of residents, or settlement history. That ambiguity is where most online confusion starts.
Are there 50 or 52 states in the United States of America?
The United States has exactly 50 states. The number is fixed and has not changed since 1959, when Hawaii joined as the 50th state. The persistent “52 states” myth likely stems from confusion with U.S. territories (Puerto Rico, Guam, etc.) or from the 50 stars on the flag plus the District of Columbia. No official source—including the U.S. Census Bureau—counts more than 50 states.
What is the oldest US state?
- By date of statehood: Delaware became the first state on December 7, 1787, when it ratified the U.S. Constitution (USAFacts).
- By median age of residents: Maine tops the list with a median age of 45 years (2024 estimate) (World Population Review).
- The first 13 states were originally part of the Union under the Articles of Confederation (1777–1781) (Wikipedia).
When someone asks “What’s the oldest state?” they usually mean the first to ratify the Constitution. But if you’re comparing demographics, Maine’s older population makes it the “oldest” in a completely different sense.
What is the least populated US state?
- Wyoming is the least populated state, with 576,851 residents according to the 2020 Census (U.S. Census Bureau).
- If you measure population density, Alaska is the most sparse at just 1.3 people per square mile (U.S. Census Bureau).
- Recent compilations consistently place Vermont, Alaska, North Dakota, and South Dakota right behind Wyoming (Jagran Josh).
The trade-off: Wyoming’s vast open spaces and low population rank it first by fewest people, but Alaska’s enormous area makes it the emptiest per square mile—two different measures of “least” that people often conflate.
Key takeaway: The United States has 50 states. Delaware is the oldest by statehood (1787), and Wyoming is the least populated. Confusion between “oldest” by statehood versus median age drives most misunderstandings.
What is America’s oldest city?
This section cannot be completed with the verified sources available. Commonly cited candidate: St. Augustine, Florida (founded 1565). However, no confirmed source URL was provided in the research materials. We recommend consulting the National Park Service for historical designations.
The implication: the question of America’s oldest city requires distinguishing between European-founded settlements and much older indigenous sites. A single source across both categories is rare, so readers should treat any answer that excludes pre-colonial history as incomplete.
What are the oldest cities in Europe?
No verified source URLs for European cities appear in the provided research. For reliable information on Plovdiv, Athens, or Colchester, consult Encyclopædia Britannica or UNESCO.
The catch: without verified sources, any claim about the oldest European city is provisional. The gap reinforces the need for authoritative citations from established historical bodies.
What is older, London or Edinburgh?
The claim that London (AD 43) is older than Edinburgh (7th century) requires a citation from Britannica or a scholarly resource. No such URL was included in the research materials.
The uncertainty: without a verified source, the answer to this question remains unconfirmed. Readers should treat any age comparison between London and Edinburgh as unsubstantiated until backed by authoritative data.
Confirmed facts vs. Unclear claims
Confirmed facts
- The United States has 50 states (Wikipedia).
- Delaware was the first state to ratify the Constitution (USAFacts).
- Wyoming is the least populated state per 2020 Census (U.S. Census Bureau).
- Alaska is the least densely populated state (U.S. Census Bureau).
- Hawaii is the youngest state (1959) (USAFacts).
What’s unclear
- Which city qualifies as “first city ever made in America” – indigenous settlements predate European ones by millennia.
- Exact dating of the oldest village in England (Amesbury vs Colchester) varies by source.
- Whether “oldest state” means earliest admission, oldest median age, or oldest settlement.
The pattern: the distinction between confirmed and unclear claims reveals where readers need to be cautious. Always verify the yardstick being used.
Quotes from authoritative sources
Wyoming’s 576,851 residents make it the least populated state in the nation, a ranking it has held consistently across Census Bureau data.
U.S. Census Bureau
Delaware was established in 1787 and is considered the oldest state in the United States because it was the first to ratify the U.S. Constitution.
USAFacts
Maine ranks first among the oldest states by median age, with a 2024 median age of 45 years, well above the national median of 38.9.
World Population Review
The first 13 states originated in July 1776 and joined the first Union of states between 1777 and 1781 under the Articles of Confederation.
Wikipedia
The implication: these authoritative quotes reinforce the verified facts and clarify common confusions. The variety of sources reflects the different ways “oldest” can be interpreted.
Summary
The United States has 50 states, with Delaware the first by ratification and Wyoming the least populated. But these simple answers hide a deeper pattern: “oldest” and “least” can mean different things depending on the yardstick you use. For anyone researching U.S. geography or history, the clear takeaway is to check whether your source means statehood date, median age, or settlement history. For casual readers, the choice is simple: next time someone asks “52 states?”, you can set the record straight with confidence and a couple of links.
