Journal Article
Demography (2018) 55 (4): 1269–1293.
Published: 02 July 2018
...Alan Barreca; Olivier Deschenes; Melanie Guldi Abstract We estimate the effects of temperature shocks on birth rates in the United States between 1931 and 2010. We find that days with a mean temperature above 80°F cause a large decline in birth rates 8 to 10 months later. Unlike prior studies, we...

Fig. 3 Estimated temperature-fertility relationship: Different functional forms for temperature. In the spline model, the estimates come from a cubic polynomial spline function with knots at daily mean temperatures (in degrees Fahrenheit) of 10, 30, 40, 70, and 90. The diurnal model captures More
