How to send files to the microdata service in Statistics Norway

Published:

1. Do not send the files until Statistics Norway asks for them.

2. Files are transferred via Statistics Norway’s secure connection.

  • Always send the data via Statistics Norway’s encrypted file transfer (guidelines here).
  • Never send data by e-mail or by post on CDs, memory sticks etc.

3. Note the following technical details:

3.1 File format

  • Preferred: SAS, STATA or SPSS files
  • Optional: Flat files in ASCII format, either semicolon divided values (sdv) or comma separated values (csv).
  • In the case of fixed position files, remember to also send the input program.

3.2 Naming files and variables

  • Permitted characters: A-z, 0-9 and _ (underscore). The name must not start with a number.
  • Not permitted: æøå, space or special characters
  • All variables in the same file must have a unique name, with a maximum of 32 characters each.
  • If you are sending more than one file, it is beneficial if the same variable has the same name wherever it appears.

3.3 Personal identification number

  • Always 11 positions (include any zero at the beginning)
  • Always a string format (character), never numeric

4. Documentation

Only send the persons/establishments and variables that the client and Statistics Norway have agreed on.

Always include the following:

  • Description of the population (unit, sample criteria)
  • Number of records in the file(s) (persons, establishments, observations) and whether there are duplicates
  • Complete variable list (name, label, position, length)
  • Relevant definitions and code lists

Notify Statistics Norway of any variables that may contain identifiable information, such as

  • Personal identification number (own or others, e.g. parents, spouse, siblings)
  • Organisation number
  • Name in plain text
  • Date of birth (own or others)
  • Address (in plain text or in code)
  • Municipality, district or basic statistical unit number/name
