What the slowdown in life expectancy improvements means for your financial planning


Date published

Life expectancy is always an important topic in the world of pensions and financial planning.

Considering how long we might live is an important assumption to make when creating a long-term financial plan. For the purpose of retirement planning, you need to be confident that you won’t run out of money before you run out of life.

In recent months, there has been much speculation that the recent history of rising life expectancy is now slowing down.

New official figures show that life expectancy in the UK has been increasing for a number of decades, until recently.

This was happening until 2011 when the UK, along with several other countries, experienced a notable slowdown in improvements in both male and female mortality.

The ONS reported that, between 2011 and 2016, the UK experienced one of the largest slowdowns in improvements in life expectancy at birth and at age 65 for both males and females, out of the various countries analysed.

The slowdown in life expectancy improvements was observed most widely across the countries analysed for 65 to 79 year olds. Women have been more affected overall by the slowdown than men.

Bucking the trend of slowing life expectancy improvements was Japan, where there has been an acceleration of mortality gains in recent years.

Alan Evans from the Office for National Statistics said:

“The slowdown in life expectancy improvements that has been observed in the UK since 2011, is also evident in a number of countries across Europe, North America and Australia. However, the UK has experienced one of the largest slowdowns in life expectancy at birth and at age 65 years for males and females.

“By contrast, Japan has come through a period with low life expectancy gains and has recently experienced an acceleration of mortality improvements, showing that even after a period of slow growth in life expectancy, a country may again return to faster improvements.”

It’s an interesting time for these figures, coinciding with the latest weekly death statistics for England and Wales which show the eighth consecutive week that the number of deaths has exceeded the five year average.

With some parts of the press attributing the high level of the weekly death rate to the recent heatwave experienced in the UK, what other factors could be contributing to the current slowdown in life expectancy improvements?

Two factors which contribute to the life expectancy slowdown are largely uncontested.

One factor is the result of changes in mortality among older people. Put simply, more older people – particularly older women – than expected given historical trends are dying.

Another undisputed factor contributing to the life expectancy slowdown is that flu contributed to excess deaths in some years, notably 2015 and also in 2017. However, the scale of this contribution is still being debated.

Beyond these two factors, views about the underlying factors are hotly contested. Some have put forward the impact of austerity measures as a contributing factor, which includes cuts to NHS funding.

It remains unclear whether the slowdown is a temporary blip or the start of a longer-term trend.

As a result of the life expectancy slowdown experienced here in the UK, we have fallen to the bottom of an international league table of life expectancy improvements for women. For men, the UK is now second bottom on the table, with only the US having a worse record.

By way of some sort of conclusion, it is no particular surprise to me that life expectancy is falling given that, generally speaking, folks these days are somewhat larger around the middle then perhaps they should be! We remain steadfast in our view that your wealth is there to be enjoyed because none of us have any way of knowing how long we will be around to spend it.
