Disclosure: I’m the creator of the website.
I have always considered this type of data useful, but I was never satisfied with the available alternatives, mainly for three reasons: 1) lack of transparency regarding the source, or the use of crowdsourced data; 2) missing, incomplete or unclear methodology; and 3) comparisons between data that are not always truly comparable.
That is why I decided to create this website: citycostatlas.com
All data has its source indicated — most of it comes from public institutions — and the methodology used to obtain the data is explained clearly. I try to ensure that the data being compared is actually comparable; when it is not fully comparable, this is indicated — for example, when comparing the sale price per m² of a house in the City of Helsinki with the value for the Greater City Area of Madrid, because they do not represent the same geographical/statistical area.
In this first version, I chose to include the capital cities of the European Union and some key costs: sale price per m² of apartments and houses, monthly rents for different dwelling types, household gas consumption between 20 GJ and 199 GJ, household electricity consumption between 2,500 kWh and 4,999 kWh, and water based on an annual consumption of 120 m³. The gas and electricity bands were chosen because they are intermediate, standardised household consumption categories used for comparison between countries. For water, I used 120 m³/year as a practical benchmark to make tariffs with different structures more comparable.
