Microdata

Microdata are small samples of data for whole households and individuals.

Microdata enables researchers to see combinations of information that would not normally be possible from standard census tables.

Microdata files do not contain any information that could identify a person or household.

All our microdata products contain information from the 2011 census in Scotland.

You can also access:

Teaching file

The microdata teaching file contains records for a random anonymous sample of 1% of Scotland’s population.

The teaching file contains less detail than other microdata files. Information is mostly presented at a high level.

Anyone can download and use the teaching file under the Open Government Licence.

Download the microdata teaching file and user guide.

Find out more about how you can use the teaching file in the ONS publication Possibilities for exploring the data.

Secure microdata files

The secure microdata files are 2 random samples of 10% of Scotland’s population. They are available only to approved researchers.

Secure microdata files have the most detail and the largest sample site of any census data products. They are protected by the highest level of access limitation.

The files are anonymous and they do not overlap.

Seucre microdata files include:

  • an individual file that includes person-level data on 146 variables for more than 534,000 people
