Page "Census" Paragraph 95

The setting up, in 1952, of the National Registry ( Þjóðskrá ) eliminated the need for censuses.

All those born in Iceland, and all new residents, are automatically registered.

Individuals are identified in the registry by means of a national identification number ( the so-called kennitala ), a number composed of the date of birth in the format and four additional digits, the third of which is a control digit, and the last of which indicates the century in which the person was born ( 9 for the 1900s and 0 for the 2000s ).
