-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - - 7 - The reduction in 1983 illustrates savings made possible by the stratified sampling scheme. The size of the sample was established to be large enough to give good estimates of general characteristics of the entire population, but it was not practical to make it so large as to give a reliable picture of a single area. In 1980 the survey form was used by about six other countries and a report prepared on the composition of the Fellowship in those countries. In 1986 the U.K. and Australia used the questionnaire again and G.S.O. processed their returns. -----BEGIN PGP SIGNATURE----- Version: PGP Personal Privacy 6.5.8 iQA/AwUBQk7nfLw9MOKEeRC8EQKpAACg8mmVNNPJDPoYHAdnm9D+HRXSWjQAmwQA 7zxaqv8w0YrBerjapw06mq5Y =yetz -----END PGP SIGNATURE-----
