In the years since President Obama first took office, more Americans are thriving, exercising and enjoying a high standard of living.

The rates of health insurance coverage are up, too, but the share of Americans who say they are in excellent health is declining.

That’s all according to a recent five-part analysis of hundreds of thousands of surveys collected since 2008 by Gallup, the polling organization, and Healthways, a health care company.

The analysis represents an attempt at understanding how American well-being has changed during the Obama presidency. Generally, people reported their lives had improved even though they gave poorer assessments of their health.
