This paper examines the distribution of deaths in life tables for the population of England and Wales as a means of exploring the way in which the length of life is steadily advancing. To assess the possibility for future extension, some extreme assumptions are made about the reduction in mortality rates for certain causes. A distinction is made between ‘anticipated' deaths and ‘senescent' deaths, the latter group falling within bounds either side of a terminal peak in the distribution of deaths by age. For males, the extreme assumptions yield a peak at age 86 with some 85 per cent of deaths within the senescent area. For females, the peak is at about age 92 with 90 per cent of deaths in the senescent area.

ABSTRACTWe examine the data and techniques underlying the estimation of mortality rates at older ages in Ireland since 1950. Previous attempts to elucidate the level and trends in mortality at advanced ages in Ireland have been frustrated by significant non-random biases arising from age exaggeration and age heaping, together with a lack of correspondence, growing with increasing age, between the exposed-to-risk estimated from census data and the death count from registration data. Applying the method of extinct generations, we re-estimate crude mortality rates and report the somewhat unexpected result that mortality rates were lower, and did not increase as steeply with age, than those recorded in the official Irish Life Tables. The reestimated crude rates show, for both sexes, a very slight decrease in mortality rates between the 1950s and 1980s up to age 90 years, with no improvement discernible at older ages. Improvements at advanced ages in Ireland have lagged behind those in England and Wales and other developed countries over the same period. The companion paper,Mortality in Ireland at Advanced Ages, 1950–2006: Part 2: Graduated Rates, Whelan (2009), graduates the crude rates and extends the method of extinct generations to estimate mortality rates of more recent, still surviving, generations.

A Factor Analysis has been made of the co-variation between the mortality rates from cancer of ten male body sites and of eight female body sites, in thirty large towns in England and Wales from 1921 to 1930. The method of analysis adopted is Hotelling's method of Principal Components.Four male and four female Factors are obtained, which together account for approximately three-quarters of the total variance.A Factor is found to be associated with cancer of the larynx, oesophagus, stomach and tongue in men and with cancer of the stomach and negatively with cancer of the breast and ovaries in women. In both sexes, the Factors are associated with an index of adverse social conditions.Another Factor is found to be associated with cancer of the rectum and bladder in men and this Factor is associated with good social conditions.A special Factor associated with cancer of the colon is unrelated to the mortality from cancer of other sites, save that in women it is negatively associated with cancer of the rectum.A Factor for cancer of the lung in men is unrelated to cancer of the larynx, and is inversely related to cancer of the tongue.We are most grateful to Dr Percy Stocks, late of the General Register Office, and to Dr W. P. D. Logan, Chief Medical Statistician of the General Register Office, for their help in providing us with the relevant basic material; and to Miss E. M. Hines, Miss A. H. Huntley and Miss M. Rogers for assistance in the calculations.

This note continues an annual series on mortality rates in Great Britain; the previous note in the series appeared in J.I.A. 107, 529 and dealt with mortality in 1978. Tables 1 and 2 below show central death-rates for Great Britain for the years from 1966 to 1979 and Tables 3 and 4 show the ratios of these rates to the corresponding average rates for the three years 1970–72, which have been taken as a standard. Death-rates in this form for the years from 1961 to 1978 have been published in earlier notes in this series. The rates for 1979 have been calculated using the deaths recorded as occurring in Great Britain in 1979 and the ‘home’ population at 30 June 1979, i.e. the number of people actually in the country at the time, as estimated by the Registrars General of England and Wales and of Scotland.

Abstract In England, Parliament introduced the ‘necessary interest rule’ through the enactment of section 115 of the Charities Act 2011 (England and Wales), allowing ‘any person interested’ in a charitable trust to initiate charity proceedings against defaulting trustees in their administration of charitable assets. Nevertheless, insufficient attention has been paid to this rule despite it being initially enacted in 1853. Parliament has refrained from clearly defining the rule, and the courts have long been grappling with its meaning in determining whether a person is eligible to sue. This paper studies the necessary interest rule by exploring the way in which the courts have interpreted it and the uncertainties surrounding its operation. It is shown that, in the context of charitable trusts, the concern of securing the due administration and execution of the trust lies at the heart of the rule. The final section of this paper discusses the significant theoretical implications of the necessary interest rule. It considers the beneficiary-enforcer debate concerning the conceptual nature of express trusts and highlights the insights that analysis of the rule can provide into this debate.

ObjectiveTo estimate the overall and infection-related neonatal mortality rate and the pathogens responsible using electronic death registrations.DesignRetrospective analysis of national electronic death registrations data.SettingEngland and Wales.PatientsNeonates aged <28 days.Main outcome measuresOverall and infection-related mortality rate per 1000 live births in term, preterm (28–36 weeks) and extremely preterm (<28 weeks) neonates; the contribution of infections and specific pathogens; comparison with mortality rates in 2003–2005.ResultsThe neonatal mortality rate during 2013–2015 (2.4/1000 live births; 5095 deaths) was 31% lower than in 2003–2005 (3.5/1000; 6700 deaths). Infection-related neonatal mortality rate in 2013–2015 (0.32/1000; n=669) was 20% lower compared with 2003–2015 (0.40/1000; n=768), respectively. Infections were responsible for 13.1% (669/5095) of neonatal deaths during 2013–2015 and 11.5% (768/6700) during 2003–2005. Of the infection-related deaths, 44.2% (296/669) were in term, 19.9% (133/669) preterm and 35.9% (240/669) extremely preterm neonates. Compared with term infants (0.15/1000 live births), infection-related mortality rate was 5.9-fold (95% CI 4.7 to 7.2) higher in preterm (0.90/1000) and 188-fold (95% CI 157 to 223) higher in extremely preterm infants (28.7/1000) during 2013–2015. A pathogen was recorded in 448 (67%) registrations: 400 (89.3%) were bacterial, 37 (8.3%) viral and 11 (2.4%) fungal. Group B streptococcus (GBS) was reported in 30.4% (49/161) of records that specified a bacterial infection and 7.3% (49/669) of infection-related deaths.ConclusionsOverall and infection-related neonatal mortality rates have declined, but the contribution of infection and of specific pathogens has not changed. Further preventive measures, including antenatal GBS vaccine may be required to prevent the single most common cause of infection-related deaths in neonates.

AbstractThe aim of this paper is to extend the analyses of our earlier work (Haberman & Bloomfield, 1988)by incorporating mortality rates of male children categorised by age and social class. Data recently made available in an annex to the Decennial Occupational Mortality Investigation are utilised to produce graduated mortality rates specific for age and social class and to extend the social class specific life tables down to cover the full age range.

The general pattern of mortality in England and Wales in the present century is well known. Mortality rates have fallen steadily, the proportionate improvement decreasing with increasing age, and being greater for females than males. The position at the oldest ages is less clear; the published figures are not conclusive as to whether mortality over age 90 is constant, increasing or decreasing.

SUMMARYData for mortality from cancer of the cervix in England and Wales by 5-year age groups and four quinquennia (1951–70) are analysed. The logarithms of the mortality rates are regressed on age group, epoch of death and epoch of birth. The factors obtained are considered in relation to particular features of the mortality pattern, such as the reversal of trend in certain age groups.
