Definition:	A key that enables two or more records belonging to the same individual to be brought together. It is represented by a code consisting of the second, third and fifth characters of a person’s family name, the second and third letters of the person’s given name, the day, month and year when the person was born and the sex of the person, concatenated in that order.

Collection and usage attributes
Collection methods:	Information about whether or not the person's date of birth is accurate should be noted. By knowing that date of birth is accurate it is possible to reduce underestimation of total service user numbers and overestimation of service users' ages.
Comments:	The linkage key is designed to make it possible to count number of clients and services they received, without counting the same client more than once. It can also be used for linking to other related data collections. It is for statistical linkage purposes only, not for case management or the tracking of individual persons. This may be done using a range of identifiers and/or keys.
