Description
|
The purpose of this domain is to capture deprivation relating to the lack of good health. The domain has a relative weight of 15% in the overall index. This has increased from 14% in the 2014 index, due to the addition of three new indicators capturing a broader range of health-related conditions. There are seven indicators in the health domain, weighted as follows. - 31% GP-recorded chronic conditions (rate per 100), age-sex standardised
- 30% Limiting long-term illness (rate per 100), age-sex standardised
- 18% Premature deaths (rate per 100,000), age-sex standardised
- 10% GP-recorded mental health conditions (rate per 100), age-sex standardised
- 4% Cancer incidence (rate per 100,000), age-sex standardised
- 4% Low birth weight (live single births less than 2.5 Kg, percentage)
- 3% Children aged 4-5 who are obese (percentage)
An indirect age-sex standardisation process was applied to five of the indicators, in order to adjust for different age and sex distributions amongst small area populations. For example, one might expect to observe a higher rate of deaths in an aging population than in one consisting predominantly of young families.
For every indicator, each area was ranked in order, with the most deprived area ranked 1 and the least deprived area ranked 1,909. These ranks were assigned to a normal distribution, with low ranks receiving a low normalised value. Factor analysis was then used to calculate the indicator weights. As with all domains, the final domain ranks were exponentially transformed, to form domain scores for use in the calculation of the overall WIMD 2019. |
