Locate the U.S. National Library of Medicines MedlinePlus web page. Then identify the link to Health, United States, 2014 (National Center for Health Statistics). On the Health, United States page, locate Data Finder and click on Life expectancy. On the ensuing page, open Tables 14 and 15.
Given the data contained therein, prepare a short presentation (PowerPoint, Prezi, or similar) detailing the changes in life expectancy from 1940 to the most recent data available. Be sure to analyze differences between genders, races, and age classifications. Have the changes been constant, equal? Why?
