The Human Life-Table Database includes the following types of data:
The HLD life tables are given in a tabular form as text files with comma-separated values. The following columns are given in each table:
|Country||United Nations 4-digit country-code followed by two digits, which are used for additional coding of ethnic groups or regions within country (when needed)|
|Year1||Beginning of the calendar period|
|Year2||End of the calendar period|
|TypeLT||Type of HLD life table (see Methodology Note)|
|Age||Lower limit of age interval (age x)|
|AgeInt||Length of age interval. Usually, has a value of 1, 4 or 5. Value 99 is used for the last age group w. In original life tables of types 1,2, and 5 it corresponds to an age group with a "+" (100+, 90+, 110+). In recalculated life tables of types 3, 4 or 6 it corresponds to the age group with q(w)=1|
|m(x)||Central death rate at age x|
|q(x)||Probability of death at age x|
|l(x)||Number of survivors to age x|
|d(x)||Death number at age x|
|L(x)||Number of person-years lived at age x|
|T(x)||Number of person-years lived after age x|
|e(x)||Life expectancy at age x|
The general structure of the text files is as follows: type 1 life table male and female, type 2 life table male and female, type 3 life table male and female and type 4 life table male and female.
The columns of the originally published life table, which are used to produce HLD life tables of types 1, 2, 5 and 6, are marked by an asterisk e.g. "l(x)*", "e(x)*".
Images of published life tables are on the web in portable document format (PDF).
This would require a copy of Adobe Acrobat Reader (version 3.0 or higher) which is available at no charge from the Adobe Homepage.
