In 2007, the Department of Health and Children in the Republic of Ireland, in conjunction with the Department of Health, Social Services and Public Safety in Northern Ireland, commissioned the University College Dublin's School of Public Health and Population Science to conduct a major cross-border study of Travellers' welfare. The study, including a detailed census of Traveller population and an examination of their health status, was expected to take up to three years to complete. The main results of the study were published in 2010.
