A table, first developed by Graunt, that presents the probability of dying in the next time interval, as a function of current age. The table provides a means of calculating life expectancy, conditional on current age.
| Males | Females |

Life table. The table records the probabilities for males and females in the USA, using 2007 information. As an example, the probability that, in the USA, a 50-year-old male lives to be at least 70 is estimated as (1 − 0.07060) (1 − 0.14302)=0.79648.
