Introduction

Mortality rate refers to the ratio between the number of death and the number of people in a particular population at a specified interval of time.

In a study, the percentage of people living for a specified period of time is referred to as survival rate. Survival (l_x) refers to the part of individuals surviving at the beginning of the age interval.

A fraction of the population dying at every year of age is referred to as age-specific mortality rate.
