Figure 5

Seasonal variations in U.S. electric utility gas consumption (a) and public construction expenditures (b). Both parameters correlated indirectly with the invasive pneumococcal disease rates (gas consumption: r –0.92 with a 22-month lag; and construction: r –0.84 with a 35-month lag). Data were obtained from the Energy Information Administration and the U.S. Census Bureau, respectively.
