Questionnaires
There were two versions of the Maternity Survey:
- Version A: ‘
The Maternity Study‘ – focused more on ante-natal care and the birth process
 - Version B: ‘
The Costs Study‘ – focused more on the costs associated with pregnancy
 
The 424 co-operating authorities were randomly divided into two groups. In no case did a single authority receive both types of questionnaire.
The response rate for the maternity study was 91.5% and the response rate for the costs study was 89.3%.
