3. Overview
1. What is housing security?
2. What do we know about its effects on health?
– Directly
– In the context of housing systems?
– In the context of intergenerational inequalities in housing?
– In the context of climate change adaptation of housing systems?
3. Based on this evidence, I will reframe:
– The benefits to health, health care expenditure and productivity of addressing insecurity in
the housing system – using an example of energy poverty and cold housing.
– The role of housing security as an apex determinant of health.
– The potential for developing an internationally comparable indicators of housing system
health.

6. Housing Insecurity and Health (Direct)
Housing Affordability Stress
negatively effects mental
health and wellbeing -
between 1 and 2 points on a
100-point mental health
measure (Bentley et al 2011)
- Particularly so for people in
the rental sector (Mason et al
2013) and people who are
insecurely employed (Bentley
et al 2016).

mental health effect?

Financial hardship
Housing quality and condition
Housing location
Poor health and disability
Energy poverty
Compromise on Suitability

8. Housing Insecurity and Health
(& the housing system)
Does renting negatively impact
on health?
• In and of itself, NO
• Largely explained by the
composition of people in
rental.
• BUT – where there is
instability or insecurity we
do see a causal effect.
Can renters and owners have
the same health?
• YES

9. Through direct and indirect effects, security is
one of the causes of the causes….
Housing security (affordability, suitability and location) shape home environments which shape health.

through improved mental
health is likely large.

17. Interventions to reduce energy poverty, and other housing
interventions, are cost-effective:
- We could spend up to $7.6 billion* to eradicate cold
housing and still be cost effective.
- If we add in other gains, like productivity gains, energy
and environmental savings, we would be prepared to
spend $7.6 billion ++.
Cost-effectiveness insights
* Given lifetime discounted health expenditure savings of $1.3 billion, and 89,600 discounted life time HALY gains, as society we would spend up to 1.3 +
$70k*89600 = $7.6 billion to eradicate cold housing and still be cost effective (valuing a HALY at GDP per capita) – just on health outcomes alone

Useful internationally comparable indicator of
housing system health
ASPIRATIONAL
By Socio-Economic Position:
Age-cohort patterns of housing
occupancy by tenure
Social housing (% stock) relative to need
Housing affordability (%HAS) in rental
and owner-occupied sectors
Distance to jobs and transport for
affordable housing developments
19
AVAILABLE
Indoor air quality (from global burden of disease
measures)
Number of informal settlements (monitored as
part of the Sustainable Development Goals).

20. Conclusions
Housing security is an apex determinant of how people are housed.
Security of tenure is a critical characteristic of healthy housing in the rental sector.
Improving security, at the population level is potentially a cost-effective prevention strategy for health.
With the rise of intergenerational inequalities and the threat of our changing climate – its importance has
increased as a prevention and mitigation strategy.
Recommend developing internationally comparably indicators of the health of our housing systems that we
can use to generate and evaluate policy.
