Google Flu Trends in 121 U.S. cities

In contrast to the unusually early spike of flu activity we saw this October, Google Flu Trends is currently showing a low level of activity in the United States. Since the strain of influenza that is active (H1N1) is novel, no one knows exactly what will happen next. However, the CDC is warning that one possibility is a second spike of flu activity, which is what occured in 1957 when another novel strain of influenza spread in the United States.

We've been chatting with public health officials about new ways we can help people understand the spread of flu during this unusual time and today we're excited to bring city level flu estimates to 121 cities in the United States.


By tracking the popularity of certain Google search queries, we're able to estimate the level of flu in near real-time. Google Flu Trends is updated daily and may provide early detection of flu activity, since traditional flu surveillance systems often take days or weeks to collect and release data. These city level estimates are "experimental," meaning they haven't been validated against official data. However, the estimates are made in a similar manner to our U.S. national estimates, which have been validated. Check out our YouTube video for a quick introduction to this system.

We're pleased to be announcing this addition to Google Flu Trends during National Influenza Vaccination Week. If you're looking for a flu vaccine location near you, please visit the flu shot finder.

Zeitgeist 2009: the collective consciousness

Curiosity — it's why we search the web. Whether searching for the latest news, a popular holiday gift, a website you've heard about, the latest singing sensation, or the trailer to a blockbuster film, you come to Google with something on your mind. And since 2001, we've been releasing our annual Zeitgeist — our view into the spirit of the times — which includes the fastest-rising Google searches (those that had the greatest surge in the past year) and most popular (those that are consistently searched in large volume, like [weather]). By exploring 2009's popular and fastest rising search terms, we're able to share a glimpse into what's been on the mind of the global community this year. 

So what has captivated the minds of searchers around the world this year? As millions of fans said goodbye to the King of Pop, Michael Jackson led the list of our top 10 fastest rising queries across the globe. And a new star was born, too — quirky pop singer Lady Gaga became a search sensation the world over. In addition to appearing on many regional fastest-rising search term lists, from the Czech Republic to Switzerland and Kenya to the United Kingdom, Lady Gaga also landed in the #7 spot on the global fastest rising list.

This year's Zeitgeist also confirms that the social web is alive and well. In a sweeping confirmation of the web's ability to connect us, both Facebook and the Spanish social-networking site Tuenti appeared on the fastest rising searches at #2 and #3 respectively. Twitter also made our global list for the first time at #4 — undoubtedly propelled by celebrity tweeters from Ashton Kutcher to Miley Cyrus. 

With the global community closely watching the swine flu epidemic, [schweinegrippe], [gripe porcina], [豬流感], [h1n1], [świńskiej grypy] and [sikainfluenssa] were heavily queried the world over. In fact, in the U.S., swine flu was searched even more than another major event of the year: the inauguration of President Obama.

In the U.S., 2009 also saw many people express their thrifty consciousness in response to the sour economy. The most popular made by hand searches including everything from baby food (#2) to laundry detergent (#6). And as more and more turned to comfort foods and recipes to make at home, [chili] became the most popular recipe searched for across the country.

It's because of curious searchers like you, and the billions of searches you do throughout the year, that our annual Zeitgeist has become an insightful look into a global mindset. So please check out our Zeitgeist site, which showcases many of these interesting trends across various categories and countries, and more about how we create the lists. We're already anticipating what trends we will see in 2010!

Searching for the next Olympics host city

Tomorrow morning, the International Olympic Committee (IOC) will decide the host for the 2016 Summer Olympic and Paralympic games. Competing for the honor are four bid cities: Chicago, Madrid, Tokyo and Rio de Janeiro.

In past years, in addition to seeing a surge in searches during the Games, we typically see a significant swell in searches leading up to the announcement about which will be the next IOC host city. Just two years ago, people from across the world turned to Google to learn more about Sochi, Russia — the newly announced host of the 2014 winter games. Similar patterns emerged across the United Kingdom as citizens searched to learn more about the London 2012 bid.

At Google we've always shared the world's interest in the Olympics, and have expressed that interest through dozens of Google doodles both while the games are occurring (last August, the Beijing Games inspired many doodles) as well as celebrating the naming of host cities (Sochi in 2007). Also, last summer the world followed along at home using our Beijing 2008 Summer Games medal tracker on their iGoogle page or through the Olympic Games onebox on Google.com.

As decision day for 2016 approaches, we have Googlers in our offices in Chicago, Madrid, Tokyo (and in Sao Paulo cheering on Rio) who are watching and cheering on their cities along with the rest of the world. With the decision tomorrow, we thought it would be interesting to see what people from the host cities and countries are searching for. We've shared some of the coolest tidbits below.

Searches from around the globe for [2016] have reached an all-time high. Search volume from Spain dwarfs Brazil, the United States and Japan:


In Chicago, searchers are looking more for info on Rio's bid than Madrid's or Tokyo's, possibly indicating that Chicago residents view Rio's bid as the most competitive:

Across Tokyo, people are searching more frequently for information about the Olympics and their city's chances of landing the 2016 games:

Searches translate to [olympics] and [olympics tokyo], in blue and red, respectively

Although Oprah is widely viewed as the most popular full-time Chicago resident in the world, Chicagoans today are searching more for the Olympics than their favorite talk show host:

In Brazil, searches for [jogos olimpicos] (olympic games) have risen 650% over the course of the year. And when looking at Brazilians' interest in [rio 2016] as a search term, the top related search was for [roda rio] (a 36-meter tall ferris wheel, capable of holding 144 passengers with a gondola for the disabled). The ferris wheel, located on Copacabana, was completed in January of this year as part of the city's Olympic bid campaign.

In Spain, search volume for [juegos olímpicos] (olympic games) has more than doubled in the last month alone.

On Google Trends, [2016 olympic decision] has been steadily moving up all day, with the largest volume of searches coming from Chicago and Atlanta:


Ultimately, it comes down to the votes of the 106 IOC members. Around the world, hundreds of Googlers, along with many millions of Google users, eagerly await their decision. Whichever city wins, we can't wait for the Games to begin.

Keep up with the latest trends using Google Search

Today, we're launching a new web search feature that will help you stay in touch with the latest trends on the web.

You might already be familiar with Hot Trends, which lists the fastest rising searches on the web at any given hour. Now, when you search Google.com and your query matches one of the top 100 fastest-rising search terms, we'll show you a graph at the bottom of page, with more information — like how popular the query is, how fast it's rising over time, and other useful data.

Below is a picture of what you'd find today if you searched for [reina capodici], who just wed American Idol star Justin Guarini. Or try another example: [gotthard base tunnel], which is set to become the longest tunnel in the world. (But make sure you search for these examples today — nothing stays hot for long.)

To coincide with this change, we've also reduced the number of trends listed on the Google Hot Trends homepage to 40 from 100. This feature, however, will show up for any query that matches the top 100. We hope this change will make for a simpler user experience, and help you focus better on the top, most interesting content.

This new feature is available in the U.S. and Japan. We hope it will help you keep up with everything there's to know about the latest trends online. No more being out of the loop at your office watercooler!

Google Domestic Trends: tracking economic sectors

Today, we're really pleased to launch Google Domestic Trends on Google Finance.

Google Domestic Trends tracks Google search traffic across specific sectors of the economy. The changes in the search volume of a given sector on google.com may provide useful economic insight. We've created 23 indexes that track the major economic sectors, such as retail, auto and unemployment.

For example, the Google Luxuries Index tracks queries like [jewelry], [rings], [diamond], [ring], [jewelers], [tiffany] and so forth. As you can see from the screenshot below, this index has seasonal spikes in December — however, in the last two years there has been a pronounced decrease as the recession made consumers wary of spending on luxury items.


The Auto-Buyers Index is also interesting, especially the dramatic 40% increase correlated with the launch of the Cash for Clunkers program in the U.S.:


These charts let you easily compare actual stocks and market indexes to Google Trends. And the data for these indexes are available for download — so you can use it with your own models.

Read more about this on the Google Finance Blog, and be sure to check out the Google Research Blog for info on Hal's research on using Google Trends data to predict economic activities.

Searching for the Wisconsin primaries

Posted by Robert Snedegar, Technical Solutions Engineer and Chief Election Tracker

We're in the midst of a big election season, and of course that means pollsters and pundits have lots to say about where it will all end. I've been curious to see if their predictions match up with trends in online searches. So as my 20% project, I devised a method to track the number of searches for each candidate's name. I wanted to visually represent the trends I found, so I plotted them onto Google Maps to see where the searches were concentrated. It's fascinating to see how people in a region have turned to the Internet to engage in the primaries.

Last Tuesday during the Wisconsin primary, the maps for Democratic queries (blue) and Republican queries (red) in Wisconsin turned out slightly different than each other. The circles are proportional to the amounts of search terms that contained the name of a Democratic or Republican candidate. Of course, the data includes queries for both positive and negative keywords for each.

From the data, we can see that Democratic candidates were searched more often in Madison, while Republican candidate queries were more widely dispersed throughout the state:

We'll continue to study interesting search trends as they apply to election queries and share other findings with you.

Update: Corrected title.

Super Tuesday wrapup

Posted by Josh Cohen, Google News Team

On Super Tuesday, voters couldn't cast their ballots online, but we were excited to see so many people turn to the Internet to participate in the election. Americans and many others from around the world sent a clear message on Tuesday -- and we heard you! Here are some of our favorite highlights:

• "Tweets" from politically-engaged Twitter users spanned a wide range of expressions. You spoke your mind: "In addition to Super Tuesday, today is also Fat Tuesday. Super Fat Tuesday -- finally, a day I can relate to!" (ejacqui, UK); you reported election results: "Can someone please explain why 10% of Californians are voting for Edwards? Don't they read the news?" (paul_irish, Boston, MA); you relayed conditions at the voting booths: "CA Precincts are worried about running out of ballots." (mizlit, Montara, CA).
  
  Of course, we had a favorite:
  
  
  
  
  
  
• Searches for [super tuesday results] hit the top of our Hot Trends list early in the afternoon and stayed number one through much of the night. Related terms like [primary results], [where do i vote] and [super tuesday exit polls] were also in the top ten for significant chunks of time. Senator Obama turned out to be the most widely-searched candidate of the day, and [health care] emerged as the most popular policy issue.
  
  
• Voters, news organizations, and candidates submitted hundreds of videos to YouTube's YouChoose08 Super Tuesday site, providing for an interesting integration of unique content all on one platform. Check out some of the top videos uploaded by voters, news organizations, and the candidates themselves. And here's one of the videos we thought captured the moment well:
  
  
  
  
  
  

What's India searching for online?

Posted by Tarkeshwar Thakur, Software Engineer and Alok Goel, Product Manager

In December 2007, for the first time in India, we released a list of most popular and fast rising searches, i.e. the Google Zeitgeist. But you don't need to wait till this December to know what was popular this year; we've just unveiled Google Trends and Google Hot Trends on Google India Labs, giving you a chance to find out what India is searching for on Google by the hour.

What's on our collective mind as we search for information? What's interesting to people right now? Hot Trends will tell you. At a glance, you'll see the huge variety of topics capturing our attention, from current events to sports to political issues to the latest Bollywood gossip. Hot Trends aren't the search terms people look for most often; those are pretty predictable, like [weather] or [games]. Instead, the Hot Trends algorithm analyzes millions of searches to find those that show an unusual and fairly sudden increase in popularity. The outcome is the Hot Trends list. Hot Trends is updated throughout the day, so check back often.

For example, the #1 Hot Trends result on January 9, 2008, was 'tata new car' because of the auto expo going on then. The associated web results and associated news search results give you more context and insight into why people were searching for 'tata new car'. You can see these results by changing the date range on the top left hand corner of the Hot Trends page. As you can see, 'tata new car' has a Hot Trend status of 'spicy' -- a measure of its popularity.

Together with Hot Trends, we also launched Google Trends for India. You can view search patterns and interest in their favorite topics. You can compare the popularity of multiple queries (e.g. different Bollywood stars) and see which cities and states search for them the most.

Looking ahead to what 'Valentines Day' might mean to us, keep checking out Hot Trends and Trends for insights into the mind of India

What's hot today?

Posted by Corey Vickrey, Software Engineer

For more than six years, we have compiled a regular list of popular searches called the Google Zeitgeist. This has been our way to highlight the sorts of queries people type into the Google search box every day. More recently, we unveiled Google Trends to show the popularity of search terms in relation to each other overtime, and how different cities or regions may care (or not) about the trends.

And today we're introducing a new toy we are calling Hot Trends. It's a new feature of Google Trends for sharing the the hottest current searches with you in very close to real time. What's on our collective mind as we search for information? What's interesting to people right now? Hot Trends will tell you. At a glance, you'll see the huge variety of topics capturing our attention, from current events to daily crossword puzzle clues to the latest celebrity gossip. Hot Trends is updated throughout the day, so check back often.

For each Hot Trend, you will see results from Google News, Google Blog Search and web search, which help explain why the search is hot. For example, the #7 item on Thursday, May 17th was the cryptic phrase [creed thoughts]. The associated news stories and blog results show that this odd term is the name of a fake website mentioned on the season finale of The Office. Mystery solved. Of course, some searches are not as easily explained. Visit the Hot Trends group to read the explanations of others and offer your own.

If you want to look further back, you can also see what queries were hot on a particular day. On Wednesday, May 16th, [melinda doolittle], [halo 3 beta], and [ge dishwasher recall] were on the Hot Trends list. If you don't know why, maybe you'll learn something.

Hot Trends aren't the search terms people look for most often -- those are pretty predictable, like [weather] or [games] or perhaps [myspace]. Yes, [sex] too. Instead, the Hot Trends algorithm analyzes millions of searches to find those that are deviating the most relative to their past traffic. And the outcome is the Hot Trends list.

In addition to Hot Trends, we've updated Google Trends so that it's easier to use and, we hope, more useful to you. In addition to viewing the top search terms by country and city, you can view the top "subregions" (e.g. states within the U.S.) across more than 70 countries. You can now compare the leading presidential candidates around the country, for instance, or find out which states have the worst mosquito problems.

With the release of Hot Trends, we're retiring the weekly Zeitgest list, but we will still compile monthly lists for each country, and will continue our annual year-end roll-ups too.

Hot Trends is currently available only in English, but we hope to release international versions in the future.
