Life expectancy at 60
Indicator | Life expectancy at 60 | |
---|---|---|
Dimension | A key form of inclusion in later stages of life deals with the ability of the elderly to remain socially integrated and live a decent life. In this regard, life expectancy at 60 may be a good proxy of their quality of life and a reflection of the social security provided to them by the State. The measurement of exclusion in this area is computed using national life expectancy at 60, as compared to the average life expectancy at 60 in lower middle income countries. | |
Defnition: | Average number of years that a person of that age can be expected to live, assuming that age-specific mortality levels remain constant. (WHO) | |
Formula | $$[dEx^{Le}]=\frac{Le_{60}^{Ref}-Le_{60}^n}{Le_{60}^{Ref}}$$ $[dEx^{Le}]$ Degree of exclusion from surviving at old age $Le_{60}^{Ref}$: : Reference value of life expectancy at 60 years $Le_{60}^{Ref}$: : Reference value of life expectancy at 60 years | |
Computation: | National level | |
Applying the formula $$[dEx^{Le}]=\frac{Le_{60}^{Ref}-Le_{60}^n}{Le_{60}^{Ref}}$$ In Excel apply the following condition IF $Le_{60}^{Ref}$ p $Le_{60}^n$ gives the value 0 If NOT apply the formula: | Sub National Level | |
The methodology used here to determine not the scores of the Index, but the values of
life expectancy at 60 at sub-national levels, is drawn from UNDP (2009)(9). This method
requires two sets of data:
(a) national life expectancy at 60 years of age, and
(b) the proportion of population that is above national life expectancy at 60 years of age.
Therefore, the computation entails the following:
• Determine the proportion of population aged 60 and older in a given year and for each subregion (for this, we will need demographic data disaggregated at sub-national level). We call this Xdi;
• Determine the median (m) of this proportion, for a given year.
Then, apply the following criteria:
If Xdi>m then Lei=Len*[1+(Xdi/100)]
If Xdi |
