    Journal of epidemiology and community health, 69 4. The mortality experiences of ethnic groups are little studied in the UK, however, because ethnicity is not captured on death certificates. We modelled the relationship between mortality, age, deprivation and ethnic proportion. We predicted mortality rates for an area that contained the maximum proportion of each ethnic group reported in any area in England and Wales, using a generalised linear model with a Poisson distribution adjusted for deprivation. Black men and women had lower life expectancies: men by 4 years and women by around 1. The Asian population had the lowest mortality of all groups over age 45 in women and over 50 in men, whereas the Black population had the highest rates throughout, except in girls under There is still diversity within these three broad ethnic groups, but our data show important residual differences in mortality for Black men and women. These ethnic life tables can be used to inform public health planning and correctly account for background mortality in ethnic subgroups of the population.

Nevertheless species diversity is a large part of the focus of biodiversity at the local and regional scale, and we will concentrate here on how to measure species diversity.

    One must make a whole series of background assumptions in order to measure species diversity for a community. Ecologists tend to ignore most of these difficulties, but this is untenable if we are to achieve a coherent theory diversity.

    The first assumption is that the subject matter is well defined. Measurement of diversity first of all requires a clear taxonomic classification of the subject matter. In most cases ecologists worry about species diversity, but there is no reason why generic diversity or subspecific diversity could not be analyzed as well.
