[OC] Average Housing prices, monthly rents and utility benchmarks across EU capitals

All data is source-linked, with the methodology, reference period and geographic scope of each value clearly shown.

The metrics in the charts are: average sale price per m² for apartments and houses, average monthly rents by dwelling type, household gas prices per kWh for annual consumption between 5,556 and 55,278 kWh, household electricity prices per kWh for annual consumption between 2,500 and 4,999 kWh, and water prices per m³ based on annual consumption of 120 m³.

For monthly rents by dwelling type, I used Eurostat / ISRP market-rent benchmarks. These are survey-based values collected from estate agencies for selected neighbourhoods in each city covered by the survey, excluding utilities and other running costs. They should be read as comparable rent benchmarks, not as official city-wide average rents.

For sale prices per m², different geographic scopes are used depending on the source, such as city, greater city area, municipality or commune. In the website users can filter the rankings by geography type, for example city vs city, greater city area vs greater city area, municipality/commune vs municipality/commune, or view all available data together for general comparison.

For electricity and gas, I used Eurostat national household price benchmarks, so these are country-level values rather than city-specific tariffs. For water, the source varies by city: where available, I used local, municipal or utility tariffs; otherwise, I used the best available national benchmark or public-data-based proxy.

Sources:

• Housing sale prices per m² are mainly based on Eurostat data where available. When Eurostat did not provide suitable data, national government sources, municipal sources, or reliable real-estate market/media sources were used.
• Monthly rents by dwelling type, electricity prices and gas prices are based on Eurostat data. Water prices are based on the best available local or national public source for each city. In some cases, the value is an official tariff or benchmark; in others, it is a public-data-based proxy normalised to typical household consumption.

Disclaimer: I built the website.

The website also includes an interactive map where users can search for a city and instantly see all available data, together with the source, methodology and geographic scope. There is also a ranking section that allows users to view the data either as a table or as a chart, as well as a city-vs-city comparison tool. For this initial version, I decided to focus only on European Union capitals, with the goal of expanding to more cities worldwide in the future if possible.

I posted this a few hours ago, but deleted it because some of the images contained errors.
