Well-being through the Lens of the Internet

We build models to estimate well-being in the United States based on changes in the volume of internet searches for different words, obtained from the Google Trends website. The estimated well-being series are weighted combinations of word groups that are endogenously identified to fit the weekly subjective well-being measures collected by Gallup Analytics for the United States or the biannual measures for the 50 states. Our approach combines theoretical underpinnings and statistical analysis, and the model we construct successfully estimates the out-of-sample evolution of most subjective well-being measures at a one-year horizon. Our analysis suggests that internet search data can be a complement to traditional survey data to measure and analyze the well-being of a population at high frequency and local geographic levels. We highlight some factors that are important for well-being, as we find that internet searches associated with job search, civic participation, and healthy habits consistently predict well-being across several models, datasets and use cases during the period studied

Big Data Measures of Well-Being: Evidence from a Google Well-Being Index in the US

We build an indicator of individual wellbeing in the United States based on Google Trends. The indicator is a combination of keyword groups that are endogenously identified to fit with weekly timeseries of subjective wellbeing measures collected by Gallup Analytics surveys. We show that such information from Big Data can be used to build a model that accurately forecasts survey-based measures of subjective well-being. The model successfully predicts the out-of-sample evolution of most subjective well-being measures at a one-year horizon. This opens up the possibility to use Big Data as a complement to traditional survey data to measure and analyze the well-being of population at high frequency and very local geographic level. We show that we can also exploit the internet search volume to elicit the main life dimensions related to well-being. We find that keywords associated with job search, financial security, family life and leisure are the strongest predictors of the variations in subjective well-being in the United States. This paper contributes to the new research agenda on data sciences by showing how Big Data can improve our understanding of the foundations of human well-being
