US Housing Market

The US housing market in one clean Parquet - the activity and affordability picture beyond a single price index: the 30-year and 15-year fixed mortgage rates, the Census median sales price of houses sold, new and existing home sales, single-family housing starts, completions, building permits, months' supply of new homes, the rental vacancy rate and the homeownership rate. Aligned on date, back to 1990. Complements our FHFA state house-price index with the demand, supply and financing side. Public domain at origin (Freddie Mac / Census); FRED is only the retrieval pipe.

European Building Permits

The leading indicator of housing supply, in one clean Parquet: building permits lead completions by one to two years, so they tell you where the pipeline is filling or drying up long before the house-price and construction-output data move. Eurostat's permit index (sts_cobp_q, 2021=100, seasonally & calendar adjusted) for residential dwellings, residential floor area and non-residential floor area - quarterly, per country. The supply side our house-price, rent and affordability products imply but don't measure; developers, housing economists and REIT analysts read it to forecast the next turn in construction and prices.

European Construction Output

The building cycle in one clean Parquet: Eurostat's monthly construction production index (2021=100, seasonally adjusted) for every European country - total construction and the building vs civil-engineering split - one row per country × series × month since 2000. A leading read on housing supply, infrastructure spend and the construction economy; joins to house prices, macro and rates on country code.

European Construction Costs & Prices

The COST and PRICE side of European construction - the missing half of our construction-output (volume) product. Eurostat's construction cost index for new residential buildings (input costs: materials + labour) and the construction producer-price index (output prices), plus the annual inflation rate of each - quarterly, per country, one clean Parquet. Read alongside construction-output it separates a real building boom from pure cost inflation; developers use the cost-vs-price gap to model margin compression, and macro desks track it as a sticky component of core inflation. Captures the brutal 2021-23 materials-and-labour cost surge in full.
