3. Multiple Decrement Life Table
• Multiple decrement models are extensions of
standard mortality models whereby there is
simultaneous operation of several causes of
decrement.A life fails because of one of these
decrements.

4. Examples of MDLT:
Double Decrement Life Table
MDLT Triple Decrement Life Table
Increment Decrement Life Table

5. Comparative Study of MDLT with Other Life Tables
CONVENTIONAL LIFE TABLE
DOUBLE DECREMENT LIFE TABLE
MDLT
INCREMENT DECREMENT LIFE TABLE
MULTIPLE DECREMENT LIFE TABLE
MULTISTATE LIFE TABLE

7. Uses of MDLT
1)Analysis of various socio-economic characterstics
of the population.
2) For studying growth and change in the labour
force and related topics.
3) Provides information on age specific rate of
accession and separation from the labor force.
4)For calculating the average number of working
hours out of the labour force.

8. Assumptions of MDLT
Each death is due to a single cause
Each individual in population has exactly the one
probability of dying from any of the causes
operating the population.
Probability of dying from any cause is
independent from the probability of dying from
other causes
MDLT is concerned with the probability that an
individual will die of a certain cause in the
presence of other causes.

14. Total Force Of Decrement
Since the number of decrement due to all
causes in the interval 𝑥 to 𝑥 + ℎ are 𝑙 𝑥, 𝑡 →
𝑙(𝑥 + ℎ, 𝑇) and the exposure is ℎ. 𝑙(𝑥, 𝑇) in the
multiple decrement, then the force of decrement
at age 𝑥 is defined as -----
=
1
lim
𝑙 𝑥+ℎ,𝑇 −𝑙(𝑥,𝑇)

15. Conclusion
• So finally we can tell that multiple decrement
life table is used for multiple purposes.where
other life table has some limitation,multiple
decrement life table can be used in such case.
