#### What is the difference between Kaplan Meier and life table?

The main difference is the time intervals, i.e., with the actuarial life table approach we consider equally spaced intervals, while with the Kaplan-Meier approach, we use observed event times and censoring times. The calculations of the survival probabilities are detailed in the first few rows of the table.

Who has constructed the first empirical life table?

The life table is historic, having been used for survival analysis during the 1700s by Daniel Bernoulli in Switzerland. A life table gives the proportion of a demographic group surviving to the end of each time interval.

## What race has the shortest lifespan?

black males
Of the four race-sex groups considered, black males have the shortest average longevity—69.0 years. Within-sex groupings, whites have the advantage for both females and males. What accounts for the higher mortality, and subsequent lower life expectancy for blacks, and especially for black men in the United States?
