CARA: Survey Methods
The results above are from a February 2008 survey including the responses of
1,007 self-identified adult Catholics from Knowledge Networks large national panel of
households, which have been assembled by regular random telephone survey methods
(probability sampling). A survey with this number of respondents has a margin of
sampling error of ±3.1 percent. As a rule of thumb, every 1 percentage point of the total
adult Catholic population is equivalent to approximately 500,000 persons. The
Knowledge Networks panel is known to closely approximate the demographic
characteristics of the U.S. population. The panel is updated on a quarterly basis and those
persons who are sampled and asked to join the Knowledge Networks panel receive
subsidized Internet access and other incentives. For those who do not own computers,
Knowledge Networks provides a television-based Internet system (MSN TV) for free.
These steps ensure that the Knowledge Networks panel is as reflective as possible of the
national population and that it is not biased towards those who have pre-existing access to
the Internet.
