Popular Poll
The Winthrop Poll is a long-term survey initiative designed to keep public
policy makers across the country in touch with the attitudes and opinions of
citizens in South Carolina and the entire southern region. It also serves to
inform South Carolinians, and southerners as a whole, of the opinions and
views of their neighbors.
It is the only regular “snapshot” of public policy attitudes of the
residents of the state of South Carolina and the South as a region. The
survey methodology of the Social & Behavioral Research Lab has been vetted
by top news organizations and their polling experts. The results have been
covered by national and international news organizations including CNN, NBC
Nightly News, ABC News, MSNBC, The New York Times, The Washington Post, the
LA Times, The Miami Herald, Politico.com, News Hour (PBS), NPR, BBC, AFP (Agence
France-Presse), Tokyo Broadcasting System, and many more.
Trained interviewers administer the polls in the telephone survey research
lab on campus. Results are shared with media, citizens, and public officials
to help public policy makers across the country stay in touch with the
attitudes and opinions of not only South Carolinians but also of those
across the region and to track those opinions over time. The first statewide
poll took place in fall 2006.

Full Methodology Statement for November 2009
Winthrop Poll
The November survey includes respondents aged 18 years and older from
Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina,
South Carolina, Tennessee, Texas, and Virginia.
This survey includes responses from 866 respondents giving results which use
all respondents a margin of error of +/- 3.33% at the 95% confidence level.
Reported results using a subset of the entire sample will naturally have a
higher margin of error.
The survey was in the field from October 24 through November 7, 2009. Phone
calls were made during weekday evenings, all day Saturdays, and Sunday
afternoons and evenings. Weekday daytime calls are not made to avoid
oversampling those who are more likely to be at home during the day (e.g.
retirees, stay-at-home-moms, etc.).
Data are weighted by state population (proportion of total 18 years and over
population for the region contained in that state), by race (within state),
by age (within state), and by sex (within state).
The survey used Random Digit Dialing (RDD) and wireless phone number
sampling. Both the RDD sample and the wireless sample were purchased from
Survey Sampling International (SSI). A further explanation of RDD
methodology, with descriptions taken from SSI’s website, may be found below.
Phone numbers selected for the survey were re-dialed five or more times in
an attempt to reach a respondent. Once a household was reached, we also
employed procedures to randomize within households.
Computerized autodialers were not used in order to ensure the survey of
wireless phones complied with the Telephone Consumers Protection Act and all
FCC rules regarding contacting wireless telephones.
Additional Explanation of RDD Methodology :
(with descriptions taken from SSI website)
Samples are generated using a database of “working blocks.” A block (also
known as a 100-bank or a bank) is a set of 100 contiguous numbers identified
by the first two digits of the last four digits of a telephone number. For
example, in the telephone number 203-567-7200, “72” is the block. A block is
termed to be working if some specified number of listed telephone numbers
are found in that block.
Samples of random numbers distributed across all eligible blocks in
proportion to their density of listed telephone households are selected. All
blocks within a county are organized in ascending order by area code,
exchange, and block number. Once the quota has been allocated to all
counties in the frame, a sampling interval is calculated by summing the
number of listed residential numbers in eligible blocks within the county
and dividing that sum by the number of sampling points assigned to the
county. From a random start between zero and the sampling interval, blocks
are systematically selected in proportion to their density of listed
households. Once a block has been selected, a two-digit number is
systematically selected in the range 00-99 and is appended to the exchange
and block to form a 10-digit telephone number.
