Correlations between Google search data and Mortality Rates
This work addresses public health monitoring by identifying potential predictive signals from search data, though it appears incremental as it extends known correlation methods from financial markets to mortality.
The paper investigated correlations between Google search data and mortality rates, finding that words with negative connotations were associated with increased mortality rates while positive words correlated with decreased rates.
Inspired by correlations recently discovered between Google search data and financial markets, we show correlations between Google search data mortality rates. Words with negative connotations may provide for increased mortality rates, while words with positive connotations may provide for decreased mortality rates, and so statistical methods were employed to determine to investigate further.
