Return of data

Where appropriate, all of these various agreements for access to data and samples from The 1958 Birth cohort will include a requirement to return new scientific data (e.g. genotypes, or new variables) to a central 1958BC scientific archive to be held at Bristol, which will increase the value of the 1958BC resource to the scientific community as a whole.

Advice on handling data

 Any outputs generated by 1958 Birth Cohort data that are to appear in the public domain must be subjected to careful disclosure control. Tables that contain very small numbers in some cells may be disclosive. Tables must not report numbers or percentages in cells based on only one or two cases. Cells based on one or two cases maybe combined with other cells or, where this is not appropriate, reported as zero per cent.
Although most outputs from models or other statistical analysis will not be disclosive, care must be taken to ensure that individuals, households or organisations cannot be identified. In particular, results based on very small numbers must be avoided. Any output that refers to unit records, e.g. a maximum or minimum value, must be avoided. Models must not report actual values for residuals.
Graphical outputs must be based on non-disclosive data. Particular care must be taken not to report extreme outliers.
