Estimates of population size and mortality for England and Wales for the period 1901-1990 are presented. "OPCS has constructed a database comprising the...number of deaths, held to the lowest level to which cause was routinely coded. The calculation of rates is made possible with this set of data by the provision of a comparable tape of estimates of population at risk. The data comprise two files, the deaths file and the population file. Each count held on the deaths file is stored in a separate record, referenced by cause, sex, age and year to which it refers. The population data are held in an identical format to that used for the death file with the exception of the cause variable, which is set to zero. The OPCS historic deaths file contains number of deaths in England and Wales by year, sex, age and ICD (International Classification of Disease) cause....The OPCS population file contains population estimates by sex, year and age." Data are from official, published, and unpublished historical sources. Information on data format and cost is available from the distributor.
