Objectives To investigate migraine patterns in the United States using Google search data and utilize this information to better understand societal‐level trends. Additionally, we aimed to evaluate time‐series relationships between migraines and social factors. Background Extensive research has been done on clinical factors associated with migraines, yet population‐level social factors have not been widely explored. Migraine internet search data may provide insight into migraine trends beyond information that can be gleaned from other sources. Methods In this longitudinal analysis of open access data, we performed a time‐series analysis in which about 12 years of Google Trends data (January 1, 2004 to August 15, 2016) were assessed. Data points were captured at a daily level and Google's 0‐100 adjusted scale was used as the primary outcome to enable the comparison of relative popularity in the migraine search term. We hypothesized that the volume of relative migraine Google searches would be affected by societal aspects such as day of the week, holidays, and novel social events. Results Several recurrent social factors that drive migraine searches were identified. Of these, day of the week had the most significant impact on the volume of Google migraine searches. On average, Mondays accumulated 13.31 higher relative search volume than Fridays (95% CI: 11.12‐15.51, P ≤ .001). Surprisingly, holidays were associated with lower relative migraine search volumes. Christmas Day had 13.84 lower relative search volumes (95% CI: 6.26‐21.43, P ≤ .001) and Thanks giving had 20.18 lower relative search volumes (95% CI: 12.55‐27.82, P ≤ .001) than days that were not holidays. Certain novel social events and extreme weather also appear to be associated with relative migraine Google search volume. Conclusions Social factors play a crucial role in explaining population level migraine patterns, and thus, warrant further exploration.
