Five Thirty Eight

Five Thirty Eight

FiveThirtyEight is a polling aggregation website with a blog created by Nate Silver. Sometimes colloquially referred to as 538 dot com or just 538, the website takes its name from the number of electors in the United States electoral college. Established on March 7, 2008, as, in August 2010 the blog became a licensed feature of The New York Times online and was renamed FiveThirtyEight: Nate Silver's Political Calculus.

During the U.S. presidential primaries and general election of 2008, the site compiled polling data through a unique methodology derived from Silver's experience in baseball sabermetrics to "balance out the polls with comparative demographic data" and "weighting each poll based on the pollster's historical track record, sample size, and recentness of the poll".

Since the 2008 election, the site has published articles – typically creating or analyzing statistical information – on a wide variety of topics in current politics and political news. These included a monthly update on the prospects for turnover in the U.S. Senate; federal economic policies; Congressional support for legislation; public support for health care reform, global warming legislation, gay rights; elections around the world; marijuana legalization; and numerous other topics.

On June 3, 2010, Silver announced that in early August the blog would be "relaunched under a domain". The transition took place on August 25, 2010, with the publication of Silver's first FiveThirtyEight blog article online in The New York Times.
