Summary
Life expectancy…
- for a person born in 2015 in MLHD is 79.5
years for males and 83.9 years for females,
this is slightly lower than NSW figures;
- has risen by 3 years for males and 2 years
for females since 2000;
- varies across the District with the highest
in Lockhart of 85.7 years to the lowest in
Narrandera of 81.2 years.
Populations of Lockhart and Coolamon are dying at
older ages than other LGAs in MLHD and also older
than NSW population in general.
On average across the LGAs women are expected
to live 4.4 years longer than men.
The gap in life expectancy at birth between the
highest ranked female population (Lockhart) and
the lowest ranked (Narrandera) is 5 years. The gap
between males of the same populations is 4.3
years.
The gap between the highest life expectancy for
females and the lowest in males is 9.2 years.

Life expectancy
Life expectancy is estimated using current death
rates by age. Life expectancy is calculated at two
stages – the life span expected for someone born in
a particular year and the life expectancy for
someone aged 65 years in that year.
Life expectancy at birth is influenced by many
factors including socioeconomic status, genetic
factors, biomedical risk factors, the quality of the
health system, including preventive health, and the
ability of people to access health care.
Life expectancy at age 65 years is influenced by
lifestyle and nutritional and environmental factors,
as well as access to and the quality of contemporary
health services.
Life expectancy in NSW and MLHD continues to
increase. In 2015:
newborn males could expect to live for 80.9 years in
NSW and 79.5 years in MLHD, while newborn
females could expect to live for 85.0 years in NSW
and 83.9 years in MLHD.
at age 65 years males could expect to live until age
85.0 years in NSW and 84.5 years in MLHD and
females until 87.6 in NSW and 87.4 years in MLHD
although females can still expect to live longer than
males, the gap between the sexes is narrowing. In
NSW life expectancy increased by 10 years for
females since 1974, whereas there has been a 10
year increase for males since 1980.
At older ages women can still expect to live longer
than men of the same age, but the difference is
smaller than the difference in life expectancy at birth
between the sexes. This reflects the fact that males
are at greater risk than women of dying before they
reach advanced age, primarily from injury, suicide
and cardiovascular disease.

Life expectancy by LGA
Life expectancy at birth in 2015 by LGA differs by
approximately four years from the highest in
Lockhart of 85.7 to the lowest in Narrandera of 81.2.
Lockhart and Coolamon in particular have
significantly higher life expectancy estimates than
all other LGAs in MLHD. As this is based on current
death rates it implies that the populations of
Lockhart and Coolamon are dying at older ages than
other LGAs in MLHD and also than NSW population
in general.

Life expectancy at birth by LGA
and sex
Life expectancy at birth for MLHD LGAs shows a
similar discrepancy between males and females as
in NSW. On average across the LGAs women are
expected to live 4.4 years longer than men.
Females with the lowest life expectancy estimate at
birth by LGA in general are likely to live longer than
males in the highest ranked LGAs with the one
exception of Narrandera females who have a similar
life expectancy of 83.0 years compared to Lockhart
males of 83.1 years.
The gap in life expectancy at birth between the
highest ranked female population (Lockhart) and
the lowest ranked (Narrandera) is 5 years. The gap
between males of the same populations is 4.3 years.
The gap between males and females in Lockhart is
4.9 years and in Narrandera is 4.2 years. The gap
between the highest life expectancy for females and
the lowest in males is 9.2 years.

Life expectancy at 65 years by
LGA and sex
Life expectancy at age 65 years for MLHD LGAs also
shows a similar discrepancy between males and
females as in NSW. On average across the LGAs
women are expected to live 3.5 years longer than
men. The gap between male and female life
expectancy at older ages is smaller than at birth as
men are more likely to die at younger ages than
women, but have more similar rates of death as
they age.
Women in Lockhart aged 65 years in 2015 can
expect to live to 90.5 years (i.e. a further 25.5 years)
and Coolamon 90.0 years, men in the same LGAs
should live to 86.4 years and 86.0 years respectively.
Females with the lowest life expectancy estimate by
LGA in general are likely to live longer than males in
the highest ranked LGAs with the one exception of
Narrandera females who have a similar life
expectancy of 86.3 years at 65 years compared to
Lockhart males of 86.4 years.

Life expectancy trend by LGA
All LGAs have experienced an increase in life
expectancy from 2005 to 2015. From birth the life
expectancy has increased on average 1.8 years and
at 65 years by 1.4 years.

Deaths from all causes by LGA
Source: Health Statistics NSW, November 2017
Death rates in the map are those which have been age-standardised taking into account the differing age
structures of LGAs across NSW. If the rates were not standardised LGAs with relatively older populations would
expect higher death rates.
MLHD LGAs generally have median ages above that of NSW (i.e. proportionally older populations). The
standardised death rates vary significantly across the LGAs. Berrigan, Narrandera and Junee all have significantly
high death rates, whereas Murrumbidgee, Coolamon and Lockhart have significantly low death rates compared
to NSW.
These high and low death rates correspond to the
longer and shorter life expectancy in the LGAs
except for Berrigan where the death rate is higher
than other LGAs but the life expectancy is in the
mid-range.
A population which is relatively older and a death
rate that is low might suggest a “well” elderly
population – i.e. we would expect a higher rate of
deaths than is actually occurring in this population
compared to NSW because it is older. Combine this
with fewer young people living in the area and you
have less chance that a death at a young age will
influence the death rate in small population areas.
Conversely if a population is relatively older
(Berrigan) but has more deaths occurring in younger
age groups than expected this could influence the
overall death rate and the life expectancy i.e. those
who survive past 75 years still live longer but more
die than expected at younger ages based on NSW
figures.
Junee death rates may be influenced by the
presence of the correctional facility, the median age
of the population is 40 and the proportion of
Aboriginal people is 7.8%. Aboriginal people in NSW
have a much shorter life expectancy (almost 10
years lower) than non-Aboriginal people.

Avoidable deaths by LGA
Avoidable deaths are those which occur before the
age of 75 years and are considered to be potentially
preventable (those amenable to screening and
primary prevention) and potentially treatable
(those amenable to therapeutic interventions).
They reflect the relative health of a population and
the access to appropriate health care.
Berrigan and Carrathool have the highest rates of
avoidable deaths in the MLHD although these are
not significantly higher than expected based on
NSW rates. Lower rates of avoidable deaths are
seen in Lockhart, Greater Hume, Snowy Valleys,
Coolamon, Gundagai and Hilltops. Low rates of
avoidable deaths add to a higher life expectancy in
the population.
