Definitions of the main concepts and variables

Resource input measured in NOK:

Own production: The sum of wage costs and purchase of goods and services, including contracting expenses for operating and maintenance services on state roads. The concept of own production should also include capital costs, but as for most other government areas, data on depreciation and amortization, real/calculated interest costs and other possible capital costs are not available for the Norwegian Public Roads Administration. Investment figures do to some extent express capital costs, but are not included in the own production. Instead, the investment figures are displayed separately. Incidentally, the Norwegian Public Roads Administration is the area of the Norwegian government where investments make up the highest share of the total costs.

Wage costs and purchase of goods and services connected to road construction projects, are classified as investments in the government accounts and the accounts of the Norwegian Public Roads Administration, but are included in the own production figures in StatRes. As a result of this, the own production figures for the Norwegian Public Roads Administration are higher in StatRes than in other accounting reports for the Norwegian Public Roads Administration. The investment figures for the Norwegian Public Roads Administration, on the other hand, will be equally lower (as described in the definition of investments).

A large share of the own production of the Norwegian Public Roads Administration is made up of costs connected to services like asphalt spreading and snow clearing carried out by private contractors. Even though the production in these cases is carried out by private contractors, the corresponding contracting costs are included in the own production of the Norwegian Public Roads Administration in StatRes (through the purchases of these services by the Norwegian Public Roads Administration).

Wage costs: Includes all expenses that the activities have in their capacity as employer, including social security contributions and pension premiums. As opposed to other areas in StatRes, other personnel costs are also included in the wage costs for the Norwegian Public Roads Administration. Personnel costs that are not wages are ordinarily classified as purchase of goods and services in StatRes. However, such personnel costs make up only a marginal fraction of the total wage costs. The wage cost figures are calculated by taking the total personnel costs for the Norwegian Public Roads Administration as a starting point. Recognised wage reimbursements are then deducted, while an estimated premium to the Norwegian Public Service Pension Fund is added (as defined below).

Estimated premium to the Norwegian Public Service Pension Fund: In the same way as most other areas in StatRes, The Norwegian Public Roads Administration does not pay pension premiums directly to the Norwegian Public Service Pension Fund, where the employees are members. These premiums, together with similar premiums for a number of other public sector activities, are instead paid in a collective transfer from the treasury to the Norwegian Public Service Pension Fund. In StatRes, however, these costs are considered to be a part of the resource input, whether they are included in the accounts or not. As these premiums are not included in the account figures for the Norwegian Public Roads Administration, a 15 per cent mark-up is applied to the reported wage costs, which roughly corresponds to the estimated costs for such premiums.

Purchase of goods and services: Includes the value of used intermediate products and services in the production. Contracting expenses for operating and maintenance services on state roads are also included (as described in the definition of own production). The starting point for the amount is the reported amounts in item 1-29, sub-post 21-29, in the national accounts and the additional financial information supplied by the Norwegian Public Roads Administration.

Investments: The investment figures in StatRes includes the contracting costs of the Norwegian Public Roads Administration for state road investments, which mainly consist of payments to contractors and other suppliers of construction and building services. State road projects which are conducted according to the model of Public Private Partnership (PPP) are included in the investments, even though parts of these expenses may be connected to financial costs or operating and maintenance costs. The basis for the investment figures is the reported amounts in item 30-49 in the national accounts and the additional financial information supplied by the Norwegian Public Roads Administration.

Construction of new roads causes the Norwegian Public Roads Administration to have large investments figures compared with most other areas in StatRes. In order to ensure coherence with other StatRes areas, wages paid to the employees of the Norwegian Public Roads Administration who plan and implement the road construction projects are included in the own production of the Norwegian Public Roads Administration. The same goes for purchases of goods and services like consulting services, travels, computer equipment, stationary and such done by the Norwegian Public Roads Administration in connection with the road construction projects. The investment figures for the Norwegian Public Roads Administration will therefore be smaller in StatRes than in other accounting reports for the Norwegian Public Roads Administration (as described in the definition of own production).

Transfers: Covers contributions to the private sector and local authorities. The starting point for the amount is the reported amounts in item 60-79 in the national accounts and the additional financial information supplied by the Norwegian Public Roads Administration. Purchases of ferry services make up the major part of the transfers figures for the Norwegian Public Roads Administration in StatRes.

Funds managed by the Norwegian Public Roads Administration for county roads : The Norwegian Public Roads Administration manages funds for county roads on behalf of the county authorities. Road tolls are also included. These funds are not included in the national accounts for the Norwegian Public Roads Administration. The number of man-years in the statistics reflects the work carried out by the Norwegian Public Roads Administration on both state and county roads.

Employment measured in contracted man-years adjusted for long term leaves:

Contracted man-years adjusted for long term leaves : The number of full-time jobs and part-time jobs calculated as full-time equivalents adjusted for doctor-certified sickness absence and maternity leave.

Standard classifications

Resource input measured in NOK :

In StatRes, expenditures are classified according to international standards for compilation of national accounts, with special weight put on the definitions in IMF's Government Finance Statistics Manual 2001 (GFSM2001). The reclassifications of account data mentioned in section 4.1 are caused by this.

Administrative information

Regional level

National level.

Frequency and timeliness

Annual.

International reporting

No.

Microdata

Historical data on the resource input in NOK is stored by Statistics Norway, and will only be used for statistical purposes. Most of the other indicators are based on the re-use of microdata which is stored in connection with Statistics Norway’s specialized statistics on similar areas or in the registers of the Norwegian Public Roads Administration.

Background

Background and purpose

The purpose of the StatRes-statistics for the Norwegian Public Roads Administration is to show the level of resources used by the central government for public roads, what this input provides in terms of activities and services, and what outcomes can be seen from the input.

The aim of StatRes is to develop and disseminate statistics and indicators of a high quality on resource input, activities, services, production and results of public sector activities. Public sector activities in this context are limited to central government. StatRes is pivotal to the development of statistics on the public sector, and aims to represent a framework for further developing the statistics that cover central government.

The StatRes project was started in 2005 and the first figures were published in 2007. The Norwegian Public Roads Administration was included in StatRes in the first quarter of 2010, with figures going back to 2006.

Users and applications

The target group of StatRes are users of statistics with some knowledge of and interest in central government activities, who require information about the use of resources, activities, services and outcome of state activities. Such users could be the general public, the media, politicians, pupils and students. StatRes shall also provide the authorities with information which supplements other information used in the administration of central government activities.

Coherence with other statistics

The StatRes indicators are based on, and should be viewed in context of, Statistics Norway’s specialized statistics on similar areas and the statistics compiled by the Norwegian Public Roads Administration. The indicators for resource input are especially developed by Statistics Norway for use in StatRes, and may in some cases differ from similar figures presented in other accounting reports for the Norwegian Public Roads Administration.

Trends in the resource input of the Norwegian Public Roads Administration should be interpreted in relation to the growth in road construction and administration costs, which for instance is estimated in the construction cost index for road construction compiled by Statistics Norway: http://www.ssb.no/bkianl_en/

When interpreting trends it is often necessary to view the indicators in context of the changes in traffic volumes, which for instance are measured in the traffic counts carried out by the Norwegian Public Roads Administration and in calculations done by Statistics Norway in cooperation with the Norwegian Institute of Transport Economics: http://www.ssb.no/transpinn_en/

Legal authority

Statistics Act sections 2-1, 2-2 (duty to provide information), 3-2 (administrative registers)

EEA reference

No.

Production

Population

The statistics show the central governments input of resources to roads and road traffic through the Norwegian Public Roads Administration, which consists of the Directorate of Public Roads and five regional offices.

The Norwegian Public Roads Administration is responsible for planning, constructing and operating the state road network, vehicle inspections and requirements, driver training and licensing. The agency is also responsible for purchasing ferry services for the state road network.

The Norwegian Public Roads Administration also manages funds for county roads on behalf of the county authorities. The number of man-years in the statistics reflects the work carried out by the Norwegian Public Roads Administration on both state and county roads. The results of the public input of resources connected to county and municipal roads is presented in the national information base on municipal and county activities, KOSTRA.

Data sources and sampling

The data basis for the indicators is collected from various sources:

Resource input measured in NOK :

The data sources are the basic data used for formulating White Paper no. 3 &– the national accounts, collected from the Government Agency for Financial Management, and additional financial information supplied by the Norwegian Public Roads Administration. Balance sheet items and net earnings are not included.

Employment measured in contracted man-years :

Statistics Norway’s register-based personnel statistics are based on individually-based register data from various registers. Information on employment conditions are taken from the Employer/Employee Register (Norwegian Labour and Welfare Service) and the Wages and Tax Deductions Register (Directorate of Taxes), and salary registers. The Central Coordinating Register of Legal Entities and the Register of Business Enterprises provide details of industries and sectors for enterprises and underlying businesses. In addition, the Norwegian Labour and Welfare Service's registers of persons on labour market initiatives, recipients of maternity pay and cash benefits, as well as Statistics Norway's register of certified sick leave are also used.

Other indicators :

The data basis for most of the other indicators is supplied by the Norwegian Public Roads Administration. The data sources within the Norwegian Public Roads Administration are registers like the Norwegian Road Data Bank (NRDB) and Autosys, registrations done in connection with planning and completing road construction projects (from the Project Data Bank and similar archives), manual reports compiled from various units in the Norwegian Public Roads Administration and annual estimates from the estimation models VSTØY/VLUFT (see also 4.1).

The number of people killed and severely injured in road traffic is taken from Statistics Norway’s road traffic accident statistics, which is based on the Police's database of accidents: http://www.ssb.no/vtu_en/

The number of cervids killed by traffic is taken from the statistics compiled by Statistics Norway based on reports from the municipal wildlife management departments: http://www.ssb.no/hjortavg_en/

Some of the pollution indicators are taken from the Norwegian emission inventory, which is estimated by Statistics Norway in cooperation with the Norwegian Climate and Pollution Agency: http://www.ssb.no/agassn_en/

Some of the traffic volume figures are taken from calculations done by Statistics Norway in cooperation with the Norwegian Institute of Transport Economics: http://www.ssb.no/transpinn_en/

The number of registered vehicles is taken from the statistics compiled by Statistics Norway based on data from the Norwegian Vehicle Register: http://www.ssb.no/bilreg_en/

The statistics are mainly based on a total count. Some of the indicators may however be based on survey samples. If so, this is specified in the definitions in section 4.1.

Collection of data, editing and estimations

The data basis for the indicators are taken from various external sources, as mentioned in sections 3.2 and 3.3.

Resource input measured in NOK:

Indicators based on accounting data are compared with the corresponding figures in the Central Government's fiscal account and the accounts of the Norwegian Public Roads Administration.

Employment measured in contracted man-years :

For the three most central registers concerning the production of the register-based employment statistics, the following checks and revision is used: The National Insurance Administration conducts an annual control of the Register of Employers and Employees. Employers using manual reporting, receive lists over all individuals registered with an active employment. Errors are reported to the Social Security offices. Statistics Norway controls that enterprises with more than one establishment have separate numbers for each, and that the employees are registered on the establishment in which they work. This is important in order to ensure correct information about industry and location of the workplace. Statistics Norway also controls the Register of Employees by comparing it with the End of the Year Certificate Register, etc.

Other indicators :

Controls and revisions are mainly carried out by the Norwegian Public Roads Administration. A visual inspection of all data is also carried out by the executive officer in Statistics Norway.

Resource input measured in NOK:

The data basis from the Government Agency for Financial Management is examined in order to identify the sections that fall within the scope of the statistics. There is only one section, 1320 the Norwegian Public Roads Administration, that covers this area of StatRes, and most amounts charged under this section are included in the basis for the estimations. The exceptions are balance sheet items and net earnings. Any amounts charged by the Norwegian Public Roads Administration under other sections of the national accounts are also included in the calculations (although these sums are relatively small). In addition to this, amounts connected to projects financed by external contributions (toll roads, advance payments, grants) and the county roads accounts are also included in the StatRes figures. Such external contributions are included in the resource input for the year in which they are spent.

The Norwegian Public Roads Administrations expenses connected to compensation of employees, purchase of goods and services, contracting expenses for operating and maintenance services on state roads, investments, transfers and county roads are supplied separately by the Directorate of Public Roads. This is due to the fact that The Norwegian Public Roads Administration uses a different grouping of some of the amounts than the one that are used in StatRes. Statistics Norway rearranges these amounts in order to ensure coherence with other StatRes areas. As a result of this, the investment figures for the Norwegian Public Roads Administration are smaller in StatRes than in other accounting reports for the Norwegian Public Roads Administration.

When calculating the resource input relating to wages, recognised wage reimbursements are deducted from the reported wage expenses (if credited in section 1320, item 15-18). On the other hand, non-reported premiums to cover the pension obligations of employees, estimated to 15 per cent of the reported gross wages, are added to the wage expenses. The reason for this is described in more detail under item 4.1.

Employment measured in contracted man-years adjusted for long term leaves:

Contracted man-years adjusted for long term leaves are calculated by Statistics Norway as the number of full-time jobs and part-time jobs calculated as full-time equivalents adjusted for doctor-certified sickness absence and maternity leave. Contracted man-years are calculated as percentage of normal full time job (37.5 hours per week). This is done on the basis of contracted working hours at the reference date, which is the third week in November in the statistical year, which is assumed to be representative for the whole year. The number of contracted man-years adjusted for long term leaves will not be identical with the man-years actually worked, since the statistics do not capture overtime, self-certified sickness absence, holiday or other deviations from agreed working hours other than doctor-certified sickness absence and maternity leave. For employees with several working engagements for the Government during the reference week, the man-years adjusted for long term leaves are calculated for each working engagement and added to each of the governmental agencies who are registered as employers.

Other indicators :

See section 4.1.

Confidentiality

Statistics Norway disseminates statistics on government agencies such as the Norwegian Public Roads Administration without consideration to confidentiality restrictions regarding the possibility of identifying the source of statistical information.

Comparability over time and space

Statistics for the Norwegian Public Roads Administration was first published in StatRes in 2010, with indicators for the years 2006-2008. Unless otherwise specified, the individual indicators are comparable from the statistical year 2006.

As a part of the public administration reform in 2010, responsibility for close to 17 000 kilometres of the previous state road grid of about 27 000 kilometres where transferred to the county authorities. Accordingly, there will be a break in the time series for the Norwegian Public Roads Administration starting from the statistics for 2010 (which is disseminated in 2011).

Accuracy and reliability

Sources of error and uncertainty

Resource input measured in NOK:

The Norwegian Public Roads Administration keeps accounts in accordance with the rules of the central government’s appropriation regulations, including circular R-101. The Office of the Auditor General of Norway carries out controls to ensure that the accounting is in accordance with these rules. Errors in the accounts data in relation to these rules are only expected to be marginal.

One weakness of the data basis is that the pension premiums are not charged at activity level. This is compensated for by Statistics Norway when processing the figures. The correction of 15 Per cent can deviate somewhat from the actual size, but Statistics Norway believes that a theoretically correct mark-up will never be far from the estimate of 15 per cent.

However, the accounts data has certain weaknesses such as the tool for measuring resource input in NOK, which can entail measurement errors. One such weakness is that the capital stock is not capitalised and depreciated, and no costs are registered in connection with the binding of government capital brought about by the activity. Inadequate registration of the capital costs in the form of depreciation and calculated interest costs normally entail the indicators for resource input measured in NOK represented by own production being lower than is actually the case.

Compensation of employees and purchase of goods and services connected to the road construction projects are included in investment figures in the accounting data for the Norwegian Public Roads Administration. In order to ensure coherence with other StatRes areas, Statistics Norway extracts these costs from investments and includes them in the own production of the Norwegian Public Roads Administration. The investment figures for the Norwegian Public Roads Administration will therefore be smaller in StatRes than in other accounting reports for the Norwegian Public Roads Administration.

Using cash accounting instead of the accruals principle is not expected to have substantial effects on the measured levels of the various amounts.

Employment measured in contracted man-years:

The data quality concerning the very shortest and most sporadic periods of employment will be poorer than for employment that has been reported to the employee register. For persons who are defined as employed only on the basis of information from Register of Wages and Deductions, the employment is not dated. This accounts for only a small share of the agreed man-hours excluding long absences in the Norwegian Public Roads Administration. For about one half of these, information is obtained from other registers so as to put a date on the period of employment. For the remainder, information about amount of annual wages is used as a basis for determining whether a person is considered to be employed. There is thus a certain degree of uncertainty whether all Register of Wages and Deductions employment was actually active on the reference date for the register-based employment statistics (third week of November).

Other indicators :

The data basis for most of the other indicators is supplied by the Norwegian Public Roads Administration (see 3.2). Control and revision of this information is carried out by the Norwegian Public Roads Administration. A visual inspection of new annual data is also carried out by the executive officer in Statistics Norway. The scope of measurement errors and processing errors in the registered data is unknown, but is not believed to introduce systematic errors in the results.

The statistics is mainly compiled from a total count of data from the registers of the Norwegian Public Roads Administration and other public register sources. Non-response errors may nevertheless occur as a result of units wrongly being left out of registers or samples used for some of the indicators. The scope of such errors in the data is not known.

There may be coverage errors in the statistics due to time gaps in registration or errors in the update of the register information used for some of the indicators. The scope of such errors in the data is not known.
