Question

Table 1 contains information about the life expectancy of Scottish children between 1861 and 2011.
Life expectancy is the additional number of years a person is expected to survive from a given age.

Table 1

Average life expectancy of child (years)

Year
from birth  from age 1  from age 15
1861  42  47  43
1891  46  52  46
1921  55  59  50
1951  66  68  55
1981  72  72  59
2011  78  77  63

(a) (i) Calculate the percentage increase in life expectancy for children born in 2011 compared to children born in 1861.

Space for calculation

___________

(ii) Give the 30 year period during which the greatest increase in life expectancy from birth occurred.

From __________ to __________

(iii) Suggest two reasons for an increase in life expectancy over the 150 year period.
