Life expectancy in Hertfordshire: frequently asked questions

What is the life expectancy in Hertfordshire?

In Hertfordshire, life expectancy at birth is 81.0 years for men and 84.3 years for women, based on Office for National Statistics period estimates for 2017-19.

What does "life expectancy at birth" mean?

Life expectancy at birth is the average number of years a baby born in the area could expect to live if 2017-19 mortality rates stayed the same throughout its life. It is a period estimate for the whole population, not a prediction for any individual.

What is healthy life expectancy in Hertfordshire?

Healthy life expectancy at birth in Hertfordshire is 65.4 years for men and 65.5 years for women (ONS, 2022-24) — the number of years a person can expect to live in "good" general health. Because life expectancy (2017-19) and healthy life expectancy (2022-24) come from different ONS releases and reference periods, the two figures are not directly subtractable.

Is life expectancy in Hertfordshire above or below the England average?

Compared with the England average for 2017-19, male life expectancy at birth in Hertfordshire is +1.2 years (81.0 years versus 79.8 years) and female life expectancy is +0.9 years (84.3 years versus 83.4 years). These are the plain differences between the ONS figures for the area and for England — no value has been adjusted.

Where does this life-expectancy data come from?

All figures come directly from the Office for National Statistics — life expectancy at birth from the "Life expectancy by local authority" dataset (2017-19) and healthy life expectancy from the "Health state life expectancies (Healthy life expectancy), UK" release (2022-24). No value is estimated or altered. The data is published under the Open Government Licence v3.0.

Methodology

Male and female life expectancy at birth are the ONS period estimates for the 2017-19 reference period, from the ONS “Life expectancy by local authority” dataset. Healthy life expectancy at birth is from the ONS “Health state life expectancies (Healthy life expectancy), UK” release for 2022-24. The two measures use different reference periods and partially different geographies, so they are not directly subtractable. Every figure is taken directly from the ONS files; no value is estimated, fabricated or altered.
