Why it matters

Why Does Gallup's Life Evaluation Index Matter?

For its Life Evaluation Index, Gallup asks people to imagine a ladder, with the lowest rung representing the worst possible life and the highest rung representing the best possible life. Those rungs are numbered zero to 10, based on the Cantril Self-Anchoring Striving Scale. People rate where they stand today and where they expect to stand in five years.

Gallup classifies those who rate their current life a 7 or higher and their anticipated life in five years an 8 or higher as thriving. Those who rate their current life and anticipated life in five years a 4 or lower are classified as suffering. Those who are neither suffering nor thriving are considered struggling.

Globally, Gallup has tracked life evaluations in at least 100 countries and areas each year since 2005, recording the highs and lows of how people have viewed their lives through major upheavals and changes -- including such events as Brexit, the Arab uprisings and the Euromaidan revolution. Since Gallup began tracking this in 2005, the percentage of the global population rating their lives highly enough to be considered thriving has ranged from a low of 21% in 2009 to a high of 29% in 2020 and 2023.

In the U.S., Gallup has tracked the Life Evaluation Index as part of domestic polling since 2008, recording the highs and lows of Americans' perceptions of their lives through the Great Recession and the COVID-19 pandemic, among other major events. Throughout that time, the percentage of Americans who are thriving has ranged from a low of 46% in November 2008 and April 2020 to a high of 59% in June 2021.

Global Methodology

The results for the 2024 life evaluation ratings are based on telephone and in-person interviews with nationally representative, probability-based samples among the adult population aged 15 and older, in 144 countries and areas throughout 2024.

For results based on the total sample of national adults in 2024, the margin of sampling error ranges between ±2.1 and ±5.4 percentage points at the 95% confidence level.

The margin of error reflects the influence of data weighting. In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.
