The Balearics is one of five regions of Spain where family income is at its highest - on or above an average of 23,240 euros per annum.
A report from business intelligence consultants, AIS, has identified the Madrid Community, the Basque Country, Catalonia and some municipalities in Cantabria as being the other regions.
Three municipalities in Madrid - Pozuelo de Alarcón, Las Rozas and Majadahonda - are the richest in Spain, with average household income being 54,543 euros.
To put this into some perspective, the average in Torrevieja in Alicante is only 8,000 euros. Pozuelo de Alarcón, moreover, has the lowest unemployment - a rate of 9.4%.
Torrevieja is not the only coastal town with a low average income. Others include Fuengirola, Torremolinos, Benidorm and Marbella.
 Unemployment is at its highest in the Cadiz province of Andalusia, where four out of the five municipalities with the highest rates of unemployment are located.
 It is almost 50% in one instance. At the other end of the scale, and in addition to Pozuelo de Alarcón, Madrid’s towns are among those with the most people in work.
Other parts of Spain with high employment include Pamplona and San Sebastian.
By specific sector, the town of Rubi in the Barcelona province has the highest level of employment in industry (42% of the employed workforce).
In certain towns, employment in industry is negligible, compared to that in services. Benidorm, for example, has over 90% employment in services.
