The mapping exercise above is suggestive of<br />
an association between <strong>SMD</strong> prevalence rates<br />
and areas of the country where poverty tends to<br />
be concentrated, and this was confirmed by an<br />
analysis of these <strong>SMD</strong> indices by levels of low<br />
income deprivation at local authority level (see<br />
Figure 9 below). The combined <strong>SMD</strong> prevalence<br />
index falls from 168 in the poorest fifth of local<br />
authorities, to 50 in the richest fifth. The pattern<br />
is strikingly similar across the three component<br />
indices, though with the NDTMS index showing<br />
the sharpest variation, and OASys almost as<br />
sharp a pattern, which is then somewhat less<br />
pronounced with regard to SP. 13<br />
Finally, we were able to use multiple regression<br />
analysis to explore the relationships at local<br />
authority level between <strong>SMD</strong> prevalence (using<br />
all three component indices and the composite<br />
index) and a range of demographic, social,<br />
economic, health and institutional factors.<br />
We found that, other things being equal, 14<br />
the factors associated with higher levels of<br />
<strong>SMD</strong> included:<br />
Measures by IMD Low<br />
s of Local Authorities<br />
• Demographic factors: having a high<br />
proportion of the population aged 16–24<br />
and/or large numbers of single person<br />
households.<br />
• Economic factors: high rates of<br />
unemployment and/or poverty.<br />
• Housing factors: housing markets with<br />
concentrations of smaller properties (e.g.<br />
bedsits and small flats). However, indicators<br />
of housing pressure (overcrowding) or low<br />
quality (lack of central heating) were not<br />
associated with areas of high <strong>SMD</strong>.<br />
• Health factors: a poor health profile amongst<br />
the local population.<br />
• Institutional factors: concentrations of<br />
institutional populations, especially those<br />
living in mental health hospitals or units, or<br />
in homeless hostels, as we might expect.<br />
There was also an association with local<br />
concentrations of holiday accommodation,<br />
tying in with the overrepresentation of<br />
seaside towns noted above.<br />
13<br />
The flatter pattern for the SP<br />
index partly reflects the fact<br />
that this is averaged across<br />
shire county areas.<br />
14<br />
In addition to the factors listed,<br />
other variables tested and<br />
discarded as non-significant<br />
included older age groups,<br />
employment rates, students,<br />
occupational class, housing<br />
tenure, non-white ethnicities,<br />
density/sparsity of population,<br />
migrant groups (e.g. new EU),<br />
and defence establishments.<br />
