National Records of Scotland have published a variety of microdata products from the 2011 census. Microdata are small samples of data for whole households and individuals, which include some associated census characteristics but no information that could identify a household or individual. Microdata products enable researchers to look at combinations of characteristics that are not generally available from the standard census tables, and to perform different types of analyses not possible from standard tabulations.
There are 3 different types of product available, with varying levels of detail and sample size:
- Microdata Teaching file - Anonymised records on a limited set of variables for a random sample of 1 per cent sample of people in the 2011 Census output database for Scotland.
- Safeguarded Microdata - two (non-overlapping) random samples, each of 5 per cent of anonymised individuals in the 2011 Census output database for Scotland (One file at Scotland level and a file at grouped council area level).
- Secure Microdata - two (non-overlapping) random samples of 10 per cent of anonymised people and households in the 2011 Census output database for Scotland. (One file that holds individual level data and a household file which includes person and household level data). The secure files represent the highest level of detail available out of all of the Microdata products.
