FiveThirtyEight facts for kids
FiveThirtyEight is a website that helps predict things like elections, sports, and other interesting topics. It also publishes articles that explain these predictions. A smart statistician named Nate Silver started it on March 7, 2008. The name "FiveThirtyEight" comes from the total number of electors in the United States Electoral College.
FiveThirtyEight became very well-known for correctly guessing the winner in all 50 states during the 2012 United States presidential election. In the 2016 election, FiveThirtyEight said that Donald Trump had about a 28.6% chance to win. Even though this seemed low to some, Trump did win. This 28.6% chance was actually much higher than what many other news groups, like The New York Times and The Economist, were predicting.
FiveThirtyEight also checks how good their predictions are. They look at something called "calibration." This means if they predict many things have a 40% chance of happening, then about 40% of those things should actually happen. Their predictions are usually quite accurate.

What is FiveThirtyEight?
FiveThirtyEight is a popular website known for its special way of looking at numbers and data. It uses these numbers to make predictions about big events. Think of it like a super-smart detective for data! The website focuses on three main areas: politics, sports, and general interest topics. It tries to figure out what might happen next based on lots of information.
How FiveThirtyEight Started
The website was created by a person named Nate Silver. He is a statistician, which means he is an expert at working with numbers and data. Nate Silver launched FiveThirtyEight on March 7, 2008. His goal was to use data and statistics to make better predictions than just guessing or relying on opinions.
The Meaning Behind the Name
The name "FiveThirtyEight" might sound a bit unusual, but it has a special meaning. It refers to the number 538. This is the exact number of electors in the United States Electoral College. The Electoral College is a system used in the U.S. to elect the president. Each state gets a certain number of electors based on its population. To win the presidency, a candidate needs to get more than half of these 538 electoral votes.
Predicting Elections with Data
One of the most famous things FiveThirtyEight does is predict election outcomes. They use a lot of different data, like public opinion polls, economic information, and historical results. They combine all this data using complex math to figure out the chances of different candidates winning.
Famous Election Predictions
FiveThirtyEight gained a lot of attention for its accurate predictions.
- 2012 Presidential Election: In the 2012 U.S. presidential election, FiveThirtyEight correctly predicted the winner in all 50 states. This was a huge achievement and showed how powerful their data-driven approach could be.
- 2016 Presidential Election: The 2016 election was a bit different. Many experts thought Donald Trump had a very low chance of winning. However, FiveThirtyEight's model gave Trump a 28.6% chance. While this was still less than 50%, it was much higher than what most other news organizations were saying. Trump ended up winning, which made FiveThirtyEight's prediction stand out. It showed that even a smaller chance can still happen.
How Accurate Are Their Forecasts?
FiveThirtyEight is always checking how good their predictions are. They use a method called "calibration." Imagine you have a special coin that lands on heads 40% of the time. If you flip it 100 times, you would expect it to land on heads about 40 times. Calibration works similarly for predictions. If FiveThirtyEight says many different events each have a 40% chance of happening, then about 40% of those events should actually occur. This helps them make sure their forecasts are reliable and trustworthy over time.
