Statement of Methodology

This survey of 500 Massachusetts residents was conducted between March 25 and March 28, 2021, and is based on live telephone interviews of adults 18 years of age or older. Each area’s quota and demographic information -- including race, education, and age -- was determined from 2010 Census data, the 2018 American Community Survey, and affiliated sources. Samples of both standard landlines (11 percent) and cell phones (89 percent) were called using a probability-proportionate-to-size method, which means that the phone numbers assigned to each area were proportional to the number of adult residents in each area. The 14 Massachusetts counties were grouped into four general regions. The margin of sampling 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.
