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.

The OOHPI is broken down into the following expenditure categories:

• O.1. Owner-occupiers’ housing expenditure;
  • O.1.1. Acquisitions of dwellings;
    • O.1.1.1. New dwellings;
      • O.1.1.1.1. Purchases of newly built dwellings;
      • O.1.1.1.2. Self-build dwellings and major renovations;
    • O.1.1.2. Existing dwellings new to households;
    • O.1.1.3. Other services related to the acquisition of dwellings;
  • O.1.2. Ownership of dwellings;
    • O.1.2.1. Major repairs and maintenance;
    • O.1.2.2. Insurance connected with dwellings;
    • O.1.2.3. Other services related to ownership of dwellings.

Households which are owner occupiers.

The main statistical variables are price indices.

The basic unit of statistical observation are transaction prices of dwellings new to the household sector and of other products that the households acquire in their role as owner-occupiers.

Owner occupied dwellings.

The OOHPI covers the entire area of the Slovenia.

Data are available since first quarter of 2010.

2015=100

The following units are used:

- Index point;
- Percentage change on the same period of the previous year (rates);
- Percentage change on the previous period (rates);
- Percentage share of the total (weights).

OOHPI is a quarterly statistics.

National legislation: National Statistics Act (OJ RS, No. 45/95 and 9/2001), Annual Programme of Statistical Surveys (LPSR) (only in Slovene).

European legislation: The basic act providing for the compilation of the House price index (HPI) and the Owner-occupied price index (OOHPI) is the European Parliament and Council Regulation (EU) 2016/792 of 11 May 2016.

The relevant implementing act is the Commission Implementing Regulation (EU) 2023/1470 of 17 July 2023.

None.

National legislation: National Statistics Act (OJ RS, No. 45/95 and 9/2001). SURS cannot publish, or otherwise make available to any individual or organization, statistics that would enable the identification of data for any individual person or legal entity. Individual data are strictly confidential and must not be published or reported.

European legislation: Regulation (EC) No 223/2009 of the European Parliament and of the Council, of 11 March 2009, on the transmission of data subject to statistical confidentiality to the Statistical Office of the European Communities.

According to policy rules (see point 7.1).

In November of each year, the SURS publishes the Release calendar giving the exact dates of releases for the coming year. The OOHPI is published in SiStat database 85 days after the end of the reference period.

The release calendar is publicly available and published on the SURS. 

The OOHPI data is released simultaneously by the issuance of the First release (on the day of publication at 10:30 CET): Residential housing price indices, namely, they are available in SiStat database. OOHPI could be obtained also via phone, fax and e-mail.

It is of interest to financial institution for monetary policy (ECB, the Bank of Slovenia) and the European Commission.

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.

All sub-indices are calculated according to the EU regulation.

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.

The time lag between the end of the period to which the OOHPI indicator relates and its national publication is 85 days.

The time lag between the actual delivery of the data and the target date when it should have been delivered is 0 days.

All input data are collected over all regions of Slovenia and they are fully comparable.

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.

Because of complexity, the overall OOHPI (aggregated from 6 sub-indices) could not be compared properly with any other known price index.

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.

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).

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.

Overview of data sources for weights derivation:

Existing dwellings new to households sector: Not calculated.

Other services related to ownership of dwellings: Not calculated.

Most data are collected quarterly. Data for weights are collected annually.

Data are acquired from administrative sources, statistical publications and HPI calculations. No special statistical surveying is needed.

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.

OOHPI is a Laspeyres-type price index.

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.

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.

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.

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.

First binding contract.

VAT is included in the price of newly built dwellings.

Other taxes are not included in the price of dwellings.

Not relevant.

Land is excluded from weights but not from all prices.

Housing cooperatives are not included.

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.

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.

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.

See below.

The hedonic method for Purchases of new dwellings was selected. For other sub-indices, in general, case-by-case approach are performed.
