Crude Death Rate (cdr) and Age Standardised Mortality Rate (asmr)

The CDR for 22007-2011 was 8.3 deaths (95% CI: 4.1-13.9) per 1,000 population, and 9.9 deaths

(95% CI: 5.4-15.3) per 1,000 population for 2002-2006. This is very similar to the CDR of 9.3 reported

in the 2006 census for the period 2001-2006.

Although a slight increase in CDR is apparent from 1987-1991 to 2007-2011, this disappears when

standardised to account for changes in the age structure of the population. As seen by the

confidence intervals shown in table 2.2 and figure 2.2 – there were no significant changes in either

CDR or ASMR over the period reported.

Both the CDR and ASMR were higher in 2002-2006, however as this increase was not sustained and

given the wide uncertainty of these figures (as reflected in the 95% CI’s), this is likely to reflect

random variation due to the small population size despite the aggregation of data over several years
