One factor that is increasingly being cited as an important economic indicator is happiness. After all, what good is increased production and consumption if the result isn’t increased human satisfaction? Until fairly recently, the subject of happiness was mostly avoided by economists for lack of good ways to measure it; however, in recent years, “happiness economists” have found ways to combine subjective surveys with objective data (on lifespan, income, and education) to yield data with consistent patterns, making a national happiness index a practical reality.
