| Methodology
eTownPanel uses a panel of volunteers who sign up to
participate in online surveys on various topics. Panelists are recruited
using the Internet and other
sources, including web directory listings, Google ads, Craigslist
postings, and announcements sent via email to membership lists of
various nonprofit organizations in New York City and nationally that
have partnered with eTownPanel over the years.
It is important to point out that the panel of respondents is not a
random
sample, and so the results are not scientifically projectable to the
larger
population. However, results are weighted by gender, race, age, and
geography to more closely reflect the general demographic profile of the
US and New York City (the focus of many of our surveys to date).
The weighting procedure involves two steps. First, weights are
constructed
to bring the sample into geographic balance based on the population of
Census regions. Second, this geographic weight is then applied to the
data, and new weights are calculated to align the sample to the Census
in terms of gender, race, and age. Most results shown in our reports are
weighted results.
The following documents show the growth of the panel over time as well
as the basic demographic profile of survey respondents (both unweighted
and weighted).

validity of eTownPanel survey results, often in comparison to
established surveys using the telephone and other more traditional
methods. (Methodology reports coming soon) |
