Crude Rates and Standardisation. Standardisation: used widely when making comparisons of rates between population groups and over time (ie. Number of health events per population) Mainly used to adjust rates so that populations with different age and sex structures can be compared
The age and sex specific rates over a 5 year period for each ward in Mansfield are applied to the European standard population to produce a rate per 100,000 population
Premature death rates in 1993 for Mansfield were 33% higher than for England in 2001
Shows a trend in the SMR: is a premature mortality <75 measure; is adjusted for age and gender differences between years: error bars show whether Mansfield ratio significantly above Trent and England ratio. The standard population rates are those for England and Wales in 2001, males and females separately, for ages <1, 1-4, then quinary ie 5-9, 10-14 etc to 85+. This explains why the national rate is 100 for 2001.
