Geography of the CAWT Region Fig 1.1: Map of Ireland illustrating the CAWT region The origins of Co-operation and Working Together (CAWT), almost 10 years ago, have cooperation and working together been described in the introduction to this report. CAWT covers the region on both sides of the border between Northern Ireland and the Republic of Ireland. Four Health Boards make up this area – The North Eastern Health Board and North Western Health Board in the Republic of Ireland, and the Southern Health and Social Services Board and Western Health and Social Services Board in Northern Ireland. Also included in CAWT are seven Health and Social Services Trusts,which are the provider organisations in Northern Ireland. The Southern Health and Social Services Board area covers the four Trusts of Craigavon Hospital, Craigavon and Banbridge Community, Armagh and Dungannon, and Newry and Mourne. The Fig 1.2: Map of CAWT region showing Western Health and Social Services Board the four Health Boards area includes Altnagelvin Hospital, Sperrin

In Northern Ireland, the population Fig 2.1 Population trends in NEHB, NWHB density in eastern counties is higher than in and four border counties/SHSSB+WHSSB the west. The imbalance in population (1901- 1999) between west and east results in the east drawing a larger share of resources and improved services. This in turn may attract people to move there because of increased employment opportunities and a better standard of living. Acknowledgement of the special difficulties of rural and isolated areas needs to be made. CAWT is one such organisation which has developed in response to this need. Life expectancy

By 1925-27 this both the NEHB and NWHB decreased until had increased to 55 years for males and 56 for the late1960s/early1970s and then increased. females.

Since 1995, the birth rate in the CAWT region has remained fairly static, due to a combination of a falling rate in Northern Ireland and a rising rate in the Republic of Ireland.

Many of these young mothers suffer from disrupted education and reduced social and occupational opportunities. In turn, they are often unable to provide a stable home and upbringing for their children. This results in increased demand for health, education and social services in the future. Fig 2.5 shows the number of births to mothers aged 15-19 in each Health Board in the CAWT region between 1990 and 1999.
