First results

Our first paper with some pilot results came out online in August 2011 and is now out in printed form. paper1

This paper shows how good our sampling procedure was, with the vast majority of volunteers having all four grandparents born within 60km of each other. 

Depending on definition, about 70% of our volunteers’ grandparents were born in rural areas and we have good coverage of the UK.
