Statement of Methodology:

This survey of 500 likely New Hampshire general election voters was conducted between October 8 and October 12, 2020, and is based on live telephone interviews of adults who indicated they were likely to vote in the November 2020 general election for president. Each area’s quota and demographic information -- including race and age -- was determined from previous general elections, 2010 census, and American Community Survey data. Samples of both standard landline and cell phones were called using a probability-proportionate-to-size method, which means that the phone numbers assigned to each county were proportional to the number of likely voters expected based on similar past elections. The 10 New Hampshire counties were grouped into four general regions. The margin of error for results based on the total sample is +/-4.4 percentage points. Error margins increase for smaller subgroups in the cross-tabulation document that follows. All surveys may be subject to other sources of error, including but not limited to coverage error and measurement error.

Statement of Methodology:

The statewide tracking survey of 500 likely Democratic primary voters consists of a two-day rolling average and includes only those respondents who indicated that they were very or somewhat likely to vote in the February 11th New Hampshire Democratic Presidential Primary. The field was conducted February 8-9, 2020, and is based on live telephone interviews. Each area’s quota and demographic information -- including geography, gender, and age -- were determined from the 2010 Census, 2018 American Community Survey, and exit polling from like elections. Samples of both standard landline (15 percent) and cell phones (85 percent) were called using a probability-proportionate-to-size method, which means that the phone numbers assigned to each county were proportionate to the number of likely voters expected based on similar open Democratic primaries in past elections. New Hampshire’s 10 counties were grouped into four general regions. Respondents in the household were selected by initially asking for the youngest adult. The margin of sampling error for results based on the total sample is plus or minus 4.4 percentage points. Error margins increase for smaller subgroups in the cross-tabulation document that follows. All surveys may be subject to other sources of error, including but not limited to coverage error and measurement error.
