Synopsis: 
This paper highlights a temporal relationship between Cuban migration and male to female live birth ratio (M/F), with M/F dipping in response to the possibility of leaving Cuba, often followed by sharp rises associated with a predominantly male efflux from the country.
ABSTRACT
 
Background: Secular trends have been found in the male-female ratio at birth (M/F: male births divided by total births) in various countries and this ratio is anticipated to approximate 0.515.
Methods: Annual national data for male and female live births in Cuba with contingency tables were obtained from the World Health Organization and analysed.
