Google Domestic Trends
Google Domestic Trends track Google search traffic across specific sectors of the economy. Changes in the search volume of a given sector on google.com may provide unique economic insight. You can access individual trend indexes by clicking on the left-hand navigation. The indexes are currently calculated only for US search traffic.
Note: the indexes measure relative query volume compared to the total number of searches on google.com. Thus, an index that is decreasing does not imply that the total number of searches is decreasing; in fact the number of queries could be increasing, just not as quickly as overall search volume.

Interesting Examples
Google Retail Index and clothing store sales
From the graph below you will see that actual clothing store sales (source) and the Google Retail index has been decreasing over time. There are seasonal spikes in clothing store sales, but over time there has been a pronounced decrease.


Google Auto Buyers Index
User searches related to car buying increased dramatically with the launch of the US Government's Cash for Clunkers program. We see that the Auto Buyers Index jumped to 1.4 at the end of July 2009.


Better Predicting real-world statistics
We wondered if Google search volumes in a month can help better predict real world statistics well before they are officially tabulated and released.

The data for these indexes are available for download—so you can use it with your own models. If you find interesting patterns and uses, feel free to share with us!
