Numbers Game

The Tsunmami death toll hit 160,000 today. I was thinking about the number of those lost vs. the number of earthlings who die each day. Then I found this website:

http://www.intellectualloafing.com/activitiesfolder/estimationqsfolder/usdeathrate.htm

It asks that we assume the following:

1) Everyone lives to the age of 75 (rough average life expectancy)

2) There is the same number of people of each age (i.e. the same number of 5 year olds as 65 year olds, people move though life as though on a conveyer belt).

3) The population is constant. This implies that 1/75 of the population are dying each year.

4) Estimate the total population of the US at 260 million.

i.e. 260 million / 75 = 3466666 people die each year

365 days in a year.

Therefore 3466666/365 = 9500 people per day. (in the U.S.)

Follow up Question: What is the global daily death rate?

Estimate the world population at 6 billion (6000 million) and 260 million in the US.

6342 * 6000 million / 260 million = 146,000 people per day.
