After a brief discussion on the joint survivorship and the joint expectation of life, the computational formula for the case in which the abridged life tables are used is presented.
For further analysis and practical purposes, as an example, the joint life expectancy in marriage by the age of the bride and the bridegroom is computed. A comparison is also made between two populations; one with a high level of mortality and the other with a low level of mortality.
In conclusion, the methodological constraints of using the constructed, model for the joint life expectancy in marriage is then discussed.
