@pewresearch: Our new analysis finds a striking correlation between Google search trends and a commonly used measure of U.S. gun sales: the number of background checks

Unlike in the aftermath of some other recent mass shootings, Google search activity did not increase in the months of the Las Vegas or Parkland attacks. Between 2012 and 2018, monthly Google search interest in the guns in our analysis increased notably in the months of several high-profile mass shootings, including those in Newtown, Connecticut, in December 2012 and in San Bernardino, California, in December 2015. (This analysis examines the calendar month in which each shooting took place, not a specific period after the shooting.)
However, there was no similar increase in monthly search activity for gun models in October 2017, when the Las Vegas shooting happened, or this past February, the month of the Parkland, Florida, high school shooting.
In fact, average search activity in those two months was lower than the average of the same month the previous year.
Again, this overall pattern is reflected in FBI background check data: The number of background checks soared in the months of the Newtown and San Bernardino attacks, but not in the months of the Las Vegas or Parkland shootings.
When considering Google search data as a research tool, its important to keep several caveats in mind. For one thing, 11% of Americans dont use the internet, which means their interest in guns cant be measured through an analysis of online searches
