In 1900, the Balearics have a rural, largely self-sufficient economy: almonds, olives, figs and fish. The islands produce most of what they need, but very little surplus. It has been this way for generations.
Many people cannot read. Few have ever left the island; those who do rarely return. They settle in Cuba, Argentina or Algiers and send money home in envelopes that may or may not arrive.
This line traces the Balearic economy in terms of GDP per head: the value produced on the islands, divided by the number of people living there. It edges up, then falls back. For decades—indeed, for generations—the average Mallorcan becomes neither steadily richer nor steadily poorer.
Then comes the Spanish civil war, triggered by Franco’s military uprising. The postwar years bring black markets and ration cards. Older Mallorcans who recall extreme hardship are not exaggerating. In the 1940s and 1950s, the islands are more isolated than ever and, by some measures, poorer than a generation before.
The outside world barely intrudes. The press reports the supposed achievements of Franco and his regime. Tourists are so few that the blue line, which records annual arrivals in millions, appears to sit at zero.
Then the first charter flights land, packed with visitors—Germans and, according to local lore, Swedish women among them. They come for sun and sand. Beaches once considered worthless are soon lined with hotels.
The hotels fill, and they need workers: waiters, bricklayers, taxi drivers and receptionists. A new service economy takes shape on islands where grain is still being threshed by hand.
The blue line—tourist arrivals—soars. The black line—Balearic income—rises with it. One million visitors become two, then three. Within 30 years, GDP per head quadruples.
Five million visitors become 10 million, then 15 million. The economy per person is now ten times larger than it was in their great-grandparents’ day. On paper, the islanders have never been richer.
