For decades, governments judged progress largely by economic growth. Gross domestic product measures the value of goods and services produced, and it rose steadily in many countries. Yet rising GDP did not always bring a matching rise in how satisfied people said they were with their lives, and critics argued that a single economic figure left out much of what matters.
Some governments now publish measures of wellbeing alongside GDP, based on surveys that ask people how satisfied they are with their lives, as well as indicators such as health, education and environmental quality. Supporters say these measures direct attention to problems that growth figures hide, such as loneliness or long commuting times.
Sceptics raise practical objections. Answers to survey questions can be influenced by mood, culture and the wording of the question, which makes comparisons between countries difficult. There is also the risk that a government might target the indicator rather than the underlying reality. Most economists now favour a dashboard of measures, in which GDP remains one important figure among several, rather than replacing one number with another.
