Data at a micro level, information about the sample and population are stored temporary in the programme language SAS. Data are long-term stored as text files on UNIX.
Background

Background and purpose
-
The purpose is to measure the price development for legal activities. The index will also be used to deflate the National Accounts. The statistics comply with the short-term statistics regulation. The statistics has been published since 2007, with figures from 1st quarter of 2005.
-

Production
-
Population
-
The population are all establishments in Norway with the NACE code Legal activities. (SIC 2002: 74.11). The statistical unit is establishment.
-
Data sources and sampling
-
Statistics Norway’s Business Register is used to draw the sample. Price data are collected via a separate questionnaire-based survey. The establishment’s turnover is based on figures from the questionnaire and Statistics Norway’s own business structural statistics.
The sample consists of about 90 establishments. We divide the establishments into size groups, determined by the number of employees. We use a PPS-sample (Probability Proportional to Size), i.e. larger establishments are more likely to be included in the sample.
-
Collection of data, editing and estimations
-
The survey is based on a quarterly questionnaire. We offer both a postal and electronic questionnaire. The questionnaire is posted by the end of the quarter, with a three weeks deadline. Respondents that have not returned the questionnaire by the deadline, are given a postal reminder together with a one-week extension of the deadline. If the questionnaire still is not returned, the respondent is given a fine and a one-week final extension of the deadline.
The postal questionnaires are read optically, and the electronic questionnaires are automatically loaded into the revision application. Every questionnaire are afterwards controlled and revised, both automatically and manually. If price changes seems unlikely large, the respondents are contacted.
The establishments are divided into three size strata. For each establishment we calculate price changes (ratios) from the price reference period to the statistical period. The individual price changes are aggregated and weighed according to the establishment’s size stratum, type of employee, type of client and type of case (civil or criminal law) in that order. All price changes are included in the total index. The weights being used are calculated from turnover in each of the categories mentioned above. The weights are being updated every other year.
-
Confidentiality
-
It is impossible to identify sensitive information from the statistics.
The use of collected data from respondents will be in accordance with the demands in the Statistics Act provisions. The information will be stored properly and kept confidential.
-
Comparability over time and space
-
The time series goes back to the 1st quarter of 2005. There has been no changes in the calculation method.
Accuracy and reliability
-
Sources of error and uncertainty
-
Errors might be caused by not correctly answered questionnaires. The respondents can state the same price even though there has been a price change from previous quarter. If something suggests a measurement error, the respondent is contacted. Data are also controlled when the questionnaires are optically read. In general, the production system ensures that the data is controlled on both detailed and aggregated level.
Non-response will always be a factor in questionnaire-based surveys. Some respondents do not return the questionnaires, or the questionnaires are rejected because they are incompletely filled out. About 97 percent of the questionnaires are returned to Statistics Norway.
The sample of 90 establishments constitutes almost 4 percent of the industry group’s population. Sampling errors are not calculated since this measurement of uncertainty is not relevant for the index.
Assuming that the prices develop homogeneously in all elementary groups, a 95 per cent confidence interval can be calculated by taking the index value and adding and subtracting the standard deviation multiplied by 2. This means that one has 95 per cent confidence that the interval covers the real value.
