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) |
| Sex | 1-males 2-females |
| 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).
