Demographic development

In the early days of Ibiza, the island was only inhabited by a few thousand people.
The first reliable records are from 1842, in which 19,447 inhabitants were counted.
In the following years and decades, Ibiza grew slowly, which is certainly due to the poor conditions of the Ibizencos during this time.
In 1920, almost 80 years after the first census in 1842, the population was 26,592 - a very small increase compared to other places in Europe at the same time.
From 1920 to 1940, however, the dynamic increased significantly to 35,441 islanders.
This was followed by twenty years of stagnation (34,339 in 1960), but progress was rapid from then on.
In 1981 there were 59,933 permanent residents on the island and twenty years later more than 88,000.
A real population explosion took place from 2001 to 2011 and the island's residents increased by around 53% (!!!) to 134,460 in these 10 years.
Today (as of 2019) 147,914 people live permanently in Ibiza, although the real number should be significantly higher, since not all islanders officially register their residence in Ibiza.
The effects on the real estate market are corresponding: real estate, regardless of whether it is a villa, finca or high-quality apartment, has continuously increased in value.
