Recent study showed that children born in the months of December, January and February are, on average are less educated, less intelligent, less healthy and lower paid as grown ups as compared to children born in other seasons.

Kasey Buckles and Daniel Hungerman of the University of Notre Dame studied U. S census data and birth certificates to determine if the typical woman giving birth in winter is any different from the typical woman giving birth at other times of the year.

Data analysis revealed that babies born in the winter are more likely to have mothers who are unmarried, who are teenagers, or who lack a high school diploma.

Buckles and Hungerman said that possible explanations include summer's high temperatures may inhibit sperm production or winter births occur nine moths after the end of prom season.
