# VIZ: Rental prices by block in Spain (El País, elDiario, July 2020)

* In July 2020, **the Spanish government published an official index of rental price**s by getting the data from the Tax Authority, the national cadastre, the Spanish Statistics Office, the property registry, the Bank of Spain and the Spanish regional authorities.

> **It's amazing how the data needed for such a public index is so much broken up and divided across so many different institutions**.

* One of the indexes published is **the evolution of the average rental price by square meter between 2015 and 2018**, which shows an increase of 19% in Malaga and Palma (two touristic cities), 17% in Barcelona, 16% in Valencia and 13% in Madrid.
* Using that data, newspapers like **El País** and **elDiario** published interactive maps where you can zoom into almost street level to see how the rental prices evolved between 2015 and 2018.
