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:
|
|||
3.3. Coverage - sector | |||
Households which are owner occupiers. |
|||
3.4. Statistical concepts and definitions | |||
The main statistical variables are price indices. |
|||

|||
10.7. Quality management - documentation | |||
Not available. |
|
|||
11.1. Quality assurance | |||
All data are checked for completeness and consistency with statistical concepts and definitions. |
|||
11.2. Quality management - assessment | |||
Not available. |
|
|||
12.1. Relevance - User Needs | |||
It is of interest to financial institution for monetary policy (ECB, the Bank of Slovenia) and the European Commission. |
|||
12.2. Relevance - User Satisfaction | |||
SURS measured general user satisfaction for the last time in 2021. Respondents assessed general satisfaction with the SURS products and services with the average score of 8.3 (on a scale from 1 – disagree completely to 10 – agree completely), there is no specific data for OOHPI. |
|||
12.3. Completeness | |||
All sub-indices are calculated according to the EU regulation. |
|
|||
13.1. Accuracy - overall | |||
There is not any estimates of the overall accuracy of the OOHPI. Overall accuracy depends on partial accuracy of 6 sub-indices calculated. Each sub-index has a specific combination of input data on average prices and weights. Each element has its own accuracy – therefore overall accuracy is difficult to assess. However, all methodological recommendations from the Methodological Manual on Owner Occupied Housing Price Indices compilation (Eurostat) have been carefully applied. |
|||
13.2. Sampling error | |||
Not available. |
|||
13.3. Non-sampling error | |||
Not available. |
|
|||

|||
14.2. Punctuality | |||
The time lag between the actual delivery of the data and the target date when it should have been delivered is 0 days. |
|
|||
15.1. Comparability - geographical | |||
All input data are collected over all regions of Slovenia and they are fully comparable. |
|||
15.2. Comparability - over time | |||
All input data are collected constantly from the same data sources and in the same way; sub-indices are calculated constantly in the same way, therefore in this view, comparability over time is maintained. |
|||
15.3. Coherence - cross domain | |||
Because of complexity, the overall OOHPI (aggregated from 6 sub-indices) could not be compared properly with any other known price index. |
|||
15.4. Coherence - internal | |||
In theory the OOHPI is consistent internally because it follows the ESA 2010 concept and the net acquisition approach concept. In practice, there is a set of different indices: 2 proxy sub-indices (for self-built dwellings and for major repairs and maintenance), one sub-index is taken directly from HPI calculations; 2 indices are related to the dwelling acquisition costs and costs associated with the ownership of dwellings. |
|
|||
Administrative and publicly available data are used. |
|
|||
17.1. Data revision - policy | |||
The published OOHPI data may be revised due to subsequent discovery of other major discrepancies (inconsistencies) in the data. Revisions must be pre-announced and is carried out in accordance with the document on the revision of statistical data (only in Slovene). |
|||
17.2. Data revision - practice | |||
The data are final when first released and are not subject to revisions. Major changes in methodology are announced in advance, while information on minor methodological changes is provided in methodological explanations and on Statistical Office's website. In June 2023 the data for 2022 have been revised. The reason for revision was due to subsequently obtained data on a larger number of sales of new residential real estate for 2021 by the GURS (The Surveying and Mapping Authority of the Republic of Slovenia) which are the basis of sub-index O.1.1.1.1. and 0.1.1.3. |

|||
18.1.2. Weights | |||
Overview of data sources for weights derivation: Purchase of new dwellings - Source: HPI, total value of new housing purchases. Self-build dwellings and major renovations - Source: NA, households housing investments (Self-build dwellings and Renovations sections). Existing dwellings new to households sector: Not calculated. Other services related to acquisition of dwellings - Source: NA – Households housing investments - 'transaction costs' section. Major repairs and maintenance - Source: NA – National Accounts - Intermediate consumption of households for housing maintenance, intended for materials and services. Insurance connected with dwellings - Source: National Insurance Association. Other services related to ownership of dwellings: Not calculated. |
|||
18.2. Frequency of data collection | |||
Most data are collected quarterly. Data for weights are collected annually. |
|||
18.3. Data collection | |||
Data are acquired from administrative sources, statistical publications and HPI calculations. No special statistical surveying is needed. |
|||
18.4. Data validation | |||
Data validation is performed by logical control of time series data. Deviations of data values in time series are a signal for closer control of input data. |
|||
18.5. Data compilation | |||
See below. |
|||
18.5.1. Calculation and Aggregation | |||
See below. |
|||
18.5.1.1. Index formulae | |||
OOHPI is a Laspeyres-type price index. |
|||
18.5.1.2. Aggregation method | |||
The OOH price index is calculated as an annually chain-linked Laspeyres-type price index. Elementary price indices are aggregated to higher level price indices and the total OOH price index. |
|||
18.5.1.3. Derivation of sub-index and elementary aggregate weights | |||
Various data sources are used for the weights, including data from national accounts (T-1), price-updated to the 4th quarter of year y-1 by using the corresponding index. This weight calculation is carried out yearly. |
|||
18.5.1.4. Price updating | |||
Various data sources are used for the weights, including data from national accounts (T-1), price-updated to the 4th quarter of year y-1 by using the corresponding index. This weight calculation is carried out yearly. |
|||
18.5.1.5. Chaining and linking method | |||
Each year indices are calculated using fourth quarter of the previous year=100 as base reference period and are rebased to 2015=100 using the chain linked method. |
|||
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 | |||
First binding contract. |
|||
18.5.2.2. Treatment of VAT | |||
VAT is included in the price of newly built dwellings. |
|||
18.5.2.3. Treatment of other taxes | |||
Other taxes are not included in the price of dwellings. |
|||
18.5.2.4. Treatment of government subsidies | |||
Not relevant. |
|||
18.5.2.5. Treatment of land | |||
Land is excluded from weights but not from all prices. |
|||
18.5.2.6. Housing cooperatives | |||
Housing cooperatives are not included. |
|||
18.5.2.7. Treatment of non-market transactions | |||
Non-market transactions such as transactions of the state and the municipalities transactions, inheritances and donations, etc. we exclude based on the indicator that identifies these transactions in the data source. |
|||
18.5.2.8. Treatment of multi-object transactions | |||
In the data source, in principle, each transaction reflects an individual properties (house or flat). Several properties are rarely sold in a package and in most cases we exclude them from the index calculation because they do not reflect the real market price. |
|||
18.5.2.9. Treatment of fractional transactions | |||
Fractional transactions are treated like other transactions (where the property is sold as a whole). If the data is incomplete or the properties of the property significantly deviate from the average, they are excluded from the calculation of the indicators. |
|||
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 | |||
