I’ve recently discovered Google Trends and have been looking for an opportunity to use it. Today I found such opportunity in a paper  published last April that computes countries’ “future orientation index” from Google Trends data and correlates it with national per-capita GDP. The authors report correlation for 2010; my experiment with Google Trends reported here tests their idea for 2011.
The paper’s authors propose that the future orientation index serves as a measurement of how much a country’s population looks forward into the future, and propose that stronger economies correlate with more future-oriented thinking. They define the future orientation index as the number of Google searches for year x+1 originating in that country during year x divided by the number of searches for year x-1 originating in that country during year x. The Google Trends query to extract such data has to include year x+1 and year x-1 at the same time so that the scaling is correct, since Google Trends reports relative search numbers rather than absolute counts. The image below shows graphical output for x = 2011. I downloaded a CSV of the output for this analysis.
The paper then demonstrates that a positive correlation exists between national per-capita GDP and the future orientation index. Here I depart from their study by dividing the 141 countries returned by Google Trends into G-20 and non-G-20 countries, and then plotting their future orientation indices in box plots:
The result shows that the economically strong G-20 countries generally have a higher future orientation index, which jives with the findings of the paper (Kruskal-Wallis rank sum test for equality: p=0.0004361; t-test that the G-20 group has greater future orientation index than the non-G-20 group: p=0.0003101).
