Blanchflower study puts the happiness curve's lowest point at age 47

At 47, happiness hits rock bottom, according to the U-shaped curve

Is there an age at which life starts going downhill? Economist David G. Blanchflower analyzed data from 132 countries and compiled 109 datasets to study the relationship between age and subjective wellbeing. The result is a U-shaped curve that appears in every country analyzed: the lowest point falls at around age 47. From there, the slope reverses and wellbeing climbs again. The thesis is not new, but its global reach makes it an uncomfortable finding for anyone who expects maturity to be an upward line.

What the U-shaped curve measures and what it leaves out

Blanchflower's work measures neither income nor objective health, but subjective wellbeing: how each person rates their own life. That nuance matters. The curve appears across all 132 countries, which suggests a common pattern, but it does not explain why. Some argue the dip coincides with the point at which responsibilities pile up — children, a mortgage, caring for parents — without pay having risen proportionally. Against this stands the argument that subjective perception depends on one's environment and personal circumstances, not just age.

The evidence circulating points in opposite directions. One 46-year-old participant says he feels "better than ever"; another claims that at 17 his life was hell, at 27 a mess, and that at 47 he was at his best. Individual experience contradicts the average. And the average, by definition, hides those above and below it.

Why some argue 47-year-olds should be earning more

The economic argument has its logic: at that age there is still enough energy to take on new responsibilities for higher pay, and there is already enough experience to justify it. If wellbeing falls just when productivity should peak, the mismatch between what is contributed and what is received may be one of the keys. The full calculation, including income, family burdens and expectations, yields a gap that does not square with the narrative of an ascending career.

There is a more uncomfortable reading: the curve does not reflect a personal problem, but a labor structure that squeezes the middle-aged band. At 47 you pay the mortgage, support your children and, increasingly, help your parents. Happiness falls because the room for maneuver narrows.

The demographic context: an age that is already the average in Spain

The average age of Spain's population is already around that range. One participant sums it up wryly: "Soon that will be the average age of Spain." The figure is no small matter. If the worst subjective age coincides with the country's average age, the malaise is not a generational anecdote but the mood of a statistical majority.

The debate on aging intersects here with the one on happiness. Part of the analysis holds that the curve could shift if medicine advances and old age stops being synonymous with decline. Others respond that the problem is not age, but the material conditions that accompany it.

In the end, the U-shaped curve is an average. And averages, like maps, are useful until you look at the terrain. At 47 you can hit rock bottom or be at the top. It depends on the mortgage, the partner, the boss and whether the body holds up. Science says one thing; life, another.
