The IMD is actually a combined index made up of several “domain indices.”
This got me wondering if any of the domain indices were particularly strongly correlated with life expectancy. I went back to the data and did a scatter plot for each of them.
The Index of Multiple Deprivation (IMD) is made up from seven domain indices as follows:
- Income – 22.5% of IMD
- Employment – 22.5% of IMD
- Education – 13.5% of IMD
- Health – 13.5% of IMD
- Crime – 9.3% of IMD
- Barriers to housing – 9.3% of IMD
- Living environment – 9.3% of IMD
Note the first of the graphs is the combined Index of Multiple Deprivation itself, so it can be seen as a comparison.
Unsurprisingly the Heath and Disability index has a strong correlation, but the Income index and the Employment index both show strong correlations too. Which for me as a trade unionist, confirms that by securing workers’ jobs and improving their pay and conditions, trade unions not only improve workers’ lives today, they also increase workers’ life expectancy over the longer term.
