Both past and recent research suggests that some groups – notably Black Caribbean, Black African and other Black groups – are over-represented in psychiatric hospitals. 
The high number of African Caribbean people being diagnosed with schizophrenia is well documented, with some studies reporting between two to eight times higher rates of diagnosis compared to the White population. 
The ‘Count me in’ census was introduced in England in 2005 and designed to support the Department of Health’s five year action plan ‘Delivering Race Equality in Mental Health Care’. The census also aimed to support the Welsh Assembly Government’s ‘Raising the Standard: Race Equality Action Plan for Adult Mental Health Services in Wales’. Key goals were to reduce rates of admission, detention and seclusion among black and minority ethnic groups.
I like how the Welsh Assembly, a rather new and ill-defined governmental body, rather than make a priority out of, say, filling potholes, decides to solve a problem that no other government has solved.
Unfortunately the figures show that these goals have not been achieved. 
Data from the 2005 ‘Count me in’ census showed that men from Black and White/Black mixed groups had the highest rates of admission to psychiatric hospitals. They were three or more times likely than the general population to be admitted. Women from the Black and mixed White/Black groups were two or more times likely than the general population to be admitted to psychiatric hospitals. Unfortunately, figures from the later surveys, including the 2009 ‘Count me in’ census, suggest the situation is still the same. 
White British, Chinese and Indian men were less likely than the average population to be admitted according to figures from all the five Count me in census reports. 
Men from Black Caribbean, Black African, and other Black groups were more likely than other groups to have been detained under the Mental Health Act 1983. The figures follow the same pattern in all the ‘Count me in’ reports from 2005 to 2009. 
Studies have shown that Irish people have higher rates of mental illness than the general population.  The Irish are often overlooked because they are White. Yet studies have found that Irish-born people living in the UK have a higher rate of suicide than any other minority ethnic group living in the country.
