July 29 (UPI) -- People around the world apparently feel that they are living better lives than they have in years and are more hopeful for the future, according to Gallup.
The global analytics and advisory firm released its Life Evaluation Index on Tuesday, which is based on the Cantril Self-Anchoring Striving Scale.
The scale asks those polled to first "Please imagine a ladder with steps numbered from zero at the bottom to 10 at the top," with the top of the ladder representing "the best possible life for you and the bottom of the ladder represents the worst possible life for you."
It then asks, "On which step of the ladder would you say you personally feel you stand at this time?" and then "On which step do you think you will stand about five years from now?"
