Period expectation of life at a given age for an area, in a given time period, is an estimate of the average number of years a person of that age would survive if they experienced the particular area’s age specific mortality rates for that period throughout the rest of their life (ONS, 2015). The figure reflects mortality among those living in the area in each time period, rather than the mortality among those born in each area. It is not therefore the number of years a person in the area in each time period could actually expect to live, both because the death rates are likely to change in the future and because many of those within the area may live elsewhere for at least part of their lives.
Period life expectancy at birth is not a guide to the remaining expectation of life at any given age. For example, if female life expectancy at birth was 80 years for a particular area, the life expectancy of women aged 65 years in that area is likely to exceed 15 years. This reflects the fact survival from a particular age depends only on the death rates beyond that age, whereas survival from birth is based on death rates at every age.
Life Expectancy at birth
The latest data, for 2012-2014, shows that life expectancy at birth is lowest for males (80.8 years) compared to females (83.9 years) in Crawley, with a gap of over three years between men and women. The gap follows the pattern for the county (80.6 years for males in West Sussex and 84.2 years for females). The figure below shows the gap in Life Expectancy at birth between men and women.
Life Expectancy at birth has increased nationally in recent years as it has in West Sussex and some of its constituent Districts, although due to the smaller number of deaths at these geographies, confidence limits around the estimates are larger and overlap. The figures below show the Life Expectancy at birth for females and for males in Crawley, West Sussex County, South East region and England.
Life Expectancy at age 65
The 2012-2014 data shows that life expectancy at age 65, as it was for life expectancy at birth, is lowest for males (19.4 years) compared to females (21.7 years). The figure below shows the gap in Life Expectancy at age 65 for men and women in Crawley and West Sussex.
Life Expectancy at age 65 has also increased nationally in recent years as it has in West Sussex and some of its constituent Districts. Again, due to the smaller number of deaths at these geographies, confidence limits around the estimates are larger and overlap, indicating that there may be no statistically significant difference over time. The tables below show the Life Expectancy at age 65 for females and for males in Crawley.
