3.1. Data description | |||
The OOHPI is based on the ‘net acquisitions’ approach, which measures changes in prices paid by households for the acquisition of dwellings that are new to the household sector and changes in other costs related to the ownership and transfer of ownership of dwellings. |
|||
3.2. Classification system | |||
The OOHPI is broken down into the following expenditure categories:
|
|||

|||
3.6. Statistical population | |||
Owner occupied dwellings. |
|||
3.7. Reference area | |||

See 10.7 quality management - documentation, 13. Accuracy, 18. Statistical processing. |
|
|||
12.1. Relevance - User Needs | |||
Main users are the Deutsche Bundesbank and the ECB. There are no official publications. |
|||
12.2. Relevance - User Satisfaction | |||
Not available. |
|||
12.3. Completeness | |||
All relevant expenditure categories defined in Commission Implementing Regulation (EU) 2023/1470, except 'Existing dwellings new to households' (O.1.1.2.). |
|
|||
13.1. Accuracy - overall | |||
Estimates of the overall accuracy of the OOHPI are not made. |
|||
13.2. Sampling error | |||
Not applicable (No probability sampling is used for the OOHPI and/or its sub-indices). |
|||
13.3. Non-sampling error | |||
O.1.1.1.1: Non-sampling errors are not quantified for the HPI. Unit and item non-response are monitored. O.1.2.2 (insurances) and O.1.1.3a (real estate agents) are collected from online portals. It is not yet known exactly how much of the respective market is covered therewith. |
|
|||

|
|||
15.1. Comparability - geographical | |||
There are no regional figures available for the OOHPI. |
|||
15.2. Comparability - over time | |||
O.1.1.1.1: The comparability of the HPI is limited by the fact that not all federal states reported data when the HPI was first set up: The geographical coverage for HPI has been improved continuously. From 2010 to 2012 nine federal states reported data for the HPI. In 2013 data collection was expanded to cover the whole economic territory of Germany. Since 2015 ECPVs of all 16 federal states transmit data. Therefore, the HPI before 2015 is not exactly comparable to the HPI after 2015. This information is shared in the metadata and the German quality report to inform users about this break.
|
|||
15.3. Coherence - cross domain | |||
Not applicable. |
|||
15.4. Coherence - internal | |||
HPI data on new dwellings are included in the OOHI compilation (O.1.1.1.1). Consistency is thereby ensured. |
|
|||
Only for O.1.1.1.1 (HPI, new dwellings) and O.1.2.2 (Insurances) new data collections were designed. The other indices are available from pre-existing statistics or public sources. O.1.1.1.1 (HPI, new dwellings): |
|
|||
17.1. Data revision - policy | |||
Revisions must be pre-announced. Each quarterly result is labeled "provisional" at the first publication and is revised with the following quarterly publication. Final results are available in June of the following year. |
|||
17.2. Data revision - practice | |||
In October 2018 the years 2015 to 2017 have been revised, due to the regular change from base year 2010 to 2015 of the construction price statistics and the producer price statistics which are the basis of O.1.1.1.2. In June 2019, there was a revision for the years 2016 to 2018 because of the adapted calculation of the HPI. |
|
|||
18.1. Source data | |||
See below. |
|||
18.1.1. Prices | |||
The index for purchase of new dwellings (O.1.1.1.1) is based on administrative data from the Expert Committees for Property Valuation (ECPVs). The ECPVs receive the purchase contracts from the notaries. (The index existing dwellings new to the household sector is not yet available.) |
|||
18.1.2. Weights | |||
Weights are mostly based on National Accounts data, on data provided by construction statistics and by service statistics. |
|||
18.2. Frequency of data collection | |||
Most data are collected quarterly, several in a monthly cycle (pre-fabricated houses, real estate agent, property management). |
|||
18.3. Data collection | |||
Data are collected by the statistical offices of the Länder and by the federal statistical office. Most data are collected for other statistics such as the construction prices. |
|||
18.4. Data validation | |||
O.1.1.1.1 (HPI -newly dwellings): O.1.1.1.2a: Application of standardised software in regional statistical offices that contains validation checks. In the federal office the regional results are analysed by cross-comparison. |
|||
18.5. Data compilation | |||
See below. |
|||
18.5.1. Calculation and Aggregation | |||
See below. |
|||
18.5.1.1. Index formulae | |||
The OOHPI should be a Laspeyres-type price index. Currently a price updating of the weights (based on data from t-1) between t-1 and q4 of t-1 is not yet implemented. It is therefore a Young index. |
|||
18.5.1.2. Aggregation method | |||
see annex 1 |
|||
18.5.1.3. Derivation of sub-index and elementary aggregate weights | |||
see annex 1 attached to 18.5.1.2 Weights are updated on a yearly basis. National accounts of t-1 data are used where available. Other statistics used for the derivation of the weights are service statistics of t-3 (for property management) and the micro census of t-4 for the ownership rate. |
|||
18.5.1.4. Price updating | |||
Weights are not yet adjusted with a price change between the year t-1 and the fourth quarter of the year t-1. |
|||
18.5.1.5. Chaining and linking method | |||
The indices are chain-linked with the fourth quarter of the last year. |
|||
18.5.2. Other processing issues - OOH sub-indices for purchases of newly built dwellings and existing dwellings new to households | |||
See below. |
|||
18.5.2.1. Timing for pricing | |||
Binding contract. |
|||
18.5.2.2. Treatment of VAT | |||
VAT is not included in the price of purchases of newly built dwellings. |
|||
18.5.2.3. Treatment of other taxes | |||
Other taxes are not included in the price of dwellings (the property transfer tax is included in O1.1.3) |
|||
18.5.2.4. Treatment of government subsidies | |||
Not relevant. |
|||
18.5.2.5. Treatment of land | |||
Land is included in the prices for purchases of newly built dwellings. Land is excluded from the weights of the OOHPI. |
|||
18.5.2.6. Housing cooperatives | |||
Housing cooperatives are not included. Housing cooperatives are included as a type of landlord in the survey for rents of the HICP. |
|||
18.5.2.7. Treatment of non-market transactions | |||
The following cases of property transactions are not to be transmitted by the ECPVs: transfer by the way of gift, expropriations, hereditary building right, inheritances, exchanges of properties. Furthermore, unusual transactions such as foreclosures (and others) are marked by the ECPVs and excluded in the course of the calculation of the HPI. |
|||
18.5.2.8. Treatment of multi-object transactions | |||
The ECPVs do not transmit multi-object transactions to us if they can not be split up into single units. |
|||
18.5.2.9. Treatment of fractional transactions | |||
The German HPI covers freehold flats, where single apartments in a multi apartment building are sold. Other fractional transactions are not included. |
|||
18.5.3. Other processing issues - OOH sub-indices other than OOH sub-indices for purchases of newly built dwellings and existing dwellings new to households | |||
See below. |
|||
18.5.3.1. Elementary aggregate formulae | |||
Construction prices: the statistical offices of the Länder calculate a geometric mean of the price relatives. The elementary aggregate for brokerage fees is a median of the surveyed percentages per region. Building insurances: the modus per adress and insurance company is used. The modus is used, because during the process of webscraping mistakes may occur which result in wrong values. |
|||
18.5.3.2. Replacements | |||
Construction prices: if a product is temporarily missing, then imputation is used (the price development is updated by the price development of the same construction work of another reporting unit). If a construction work is permanently no longer available, then the price collection of a similar construction work within the given framework for the respective construction work is used. |
|||
18.5.3.3. Quality adjustment | |||
Construction prices: Depending on the specific case judgmental quality adjustment or price change taken as quality change (companies are asked to indicate changes in the type or quality of the construction work in the questionnaire. |
|||
18.5.3.4. Missing prices | |||
For construction prices: see 18.5.3.2. Replacements. For building insurances: scraping is repeated in case of missing prices due to errors. If this does not lead to a result, then premiums are again collected manually (using the online tools). It is problematic, if an online calculator is not available any more. Then the last price is updated by an adjustment factor, that is published by the GdV (general association of the German insurance industry). If an online calculator is permanently not available any more, then the respective insurance company is excluded from the calculation beginning with the respective next June. Weights for the other insurances are adapted accordingly. |
|||
18.5.3.5. Discounts and inducements | |||
not applicable. |
|||
18.5.3.6. Zero prices | |||
Not applicable. |
|||
18.5.3.7. Treatment of VAT | |||
VAT is included in the observed prices with the exception of O.1.2.2: there is no VAT for residential building insurances, instead there is an insurance tax. |
|||
18.6. Adjustment | |||
There is no seasonal adjustment or time series decomposition. |
|
|||
None. |
