The developed world is bearing witness to a 21st century miracle – the real possibility of living well to the age of 100 and beyond. Compelling scientific evidence indicates that living long and living well is most realistic for those who adopt healthy behaviors, are financially secure, and are socially engaged.

THE SIGHTLINES PROJECT investigates how well Americans are doing in each of these three areas over historical time. We assessed the number of Americans who are meeting expert recommendations for healthy living, financial security, and social engagement. These results are intended to stir national debate, guide policy development, stimulate entrepreneurial innovation, and encourage personal choices that enhance independent, 100-year lives.
