System of arrangement
The collection consists of questionnaires arranged into four sections of interviews and responses of 1, 2, 3 and 4 year-olds with additional sections on sibling and environmental sub-studies. Each twin and parent is assigned a unique identifier number that is retained throughout the course of the project. The identifier comprises a four or five digit number for each family/parent and a three number suffix unique to the individual child. Within each annual series, the questionnaires are divided into sets of three for the mother and each of the twins, colour coded between years for quick reference, and into a number of tranches comprising several hundred names arranged in broadly numerical order. These batches were created when raw questionnaires were sent for data inputting and the arrangement has been retained for ease of recovery of particular files. The Archives possess a master list of families and twins with identifier numbers and box locations. Some twins' files have been retained by the SGDP and this is noted on spreadsheet indexes.
