In January 2012, the New York Times
published a story called “Twin Births in the U.S., Like Never
Before,” in which they reported a 76 percent increase in the
rate of twin births from 1980 to 2009. The dataset gives the number
of twin births each year (per 1000 live births). Can you confirm the Times report?
The dataset also includes the atmospheric CO2 levels (ppm) for those years to offer an alternative predictor in case there appears to be an argument for causation.
