“…An emerging literature suggests that these sources-and Google search data in particular-can be used to monitor a number of social and biological phenomena in the absence of more reliable or timely data (Cesare et al 2018). Such data have been used for real-time analyses of disease outbreaks such as the seasonal flu and Dengue (Ginsberg et al 2009;Carneiro and Mylonakis 2009) as well as studies on well-being (Brodeur et al 2021), tourism (Siliverstovs and Wochner 2018), financial trading behavior (Preis et al 2013), and demographic processes such as fertility (Billari, D'Amuri, and Marcucci 2016;Ojala et al 2017;Lin, Cranshaw, and Counts 2019), migration (Zagheni and Weber 2012;Wladyka 2017), sexual behavior (Markey and Markey 2013;Wilde, Apouey, and Jung 2017;Stephens-Davidowitz 2017), mortality (Tamgno, Faye, and Lishou 2013;Ricketts and Silva 2017), and suicide (Solano et al 2016). Moving beyond now-casting with Google data is generally difficult due to the complexity or uncertainty surrounding the longterm processes which govern such phenomena.…”
