asked the Secretary of State for Social Services what was the number of actual deaths in each week from 1 January to 31 March each year since 1979, what was the expected number of deaths for each of those weeks based on historical experience, and what was the percentage difference between the two.

[pursuant to her replies, 21 January 1987, c. 623 and 25 February 1987, c. 328–30]: The calculations on the expected number of weekly deaths at age one year and over for the years 1979 to 1982 have been completed, and the figures are shown in the tables. Also shown is the information carried forward for the current year.An explanation of the methods used to calculate the expected number of deaths is given in "Population Trends No. 34", a copy of which is in the Library.

Numbers of deaths at age 1 year and over registered each week (actual deaths), expected deaths based on experience of previous ten years, and percentage differences: Week 1 to Week 13, 1979–1987 (England and Wales)

Expected figures calculated using 1981 projected populations based on the mid-1979 total population (estimated from 1971 census data).

1 Actual deaths averaged for the three weeks covering Christmas and new year.

2 Actual deaths in the two weeks containing Easter Friday and Easter Sunday are averaged.

Figures for actual deaths are based on occurrences rather than registrations due to the registrars' dispute.

3 Actual deaths averaged for the four weeks covering Christmas and New Year.
