International: Children’s life chances are decided by the age of three, report finds
Swindon Advertiser – January 04, 2017
The study in question is known as ‘The Dunedin Study’, based in New Zealand but involving researchers from the US and UK. The 40-year longitudinal study has followed over 1,000 individuals who were born between 1972 and 1973 and shows how it is possible to predict which three year olds will grow up to become criminals, which will claim benefits and which will have poor health in later life.
