This report updates birth seasonality for 28 European/Mediterranean countries and evaluates the possible influence of atmospheric clarity/quality on seasonality.
Birth data between 1970 and 2011 were adjusted for seasonality and are presented as conceptions.
Presently, 27 of 28 countries have peak conceptions during the last 3 months of the year, a greater concentration than was previously recognized.
There is no apparent explanation for the en masse transition of seasonality, particularly the abrupt change in seasonality for nine countries, The frequency of sexual intercourse might be a one determinant while another possibility might be the decadal changes in atmospheric clearness/quality. However, causal relationships cannot be inferred without further study and/or animal experimentation. Am. J. Hum. Biol. 26:424–426, 2014. © 2014 Wiley Periodicals, Inc.
