METHODOLOGY
Change Research surveyed 1,033 registered voters ages 18-34 nationwide from August 25-September 1, 2023. Change Research self-funded this research for public release. We used the following sources to recruit respondents:
● targeted advertisements using the Meta advertising platform
● SMS text messages
Regardless of which of these sources a respondent came from, they were directed to a survey hosted on SurveyMonkey’s website.
Ads placed on social media targeted likely voters nationwide. Those who indicated that they were not registered to vote were terminated. Those who indicated they were over the age of 34 were terminated. As the survey fielded, Change Research used dynamic online sampling: adjusting ad budgets, lowering budgets for ads targeting groups that were overrepresented, raising budgets for ads targeting groups that were underrepresented. The survey was conducted in English. The survey was conducted online by Change Research. Post-stratification weighting was performed on age, gender, region, education, ethnicity, and 2020 presidential vote. Weighting parameters were based on the demographic composition of likely voters nationwide, obtained from the voter file. The modeled margin of error* for this survey is 3.4%, which uses effective sample sizes** that adjust for the design effect of weighting.

Honestly how can one even conduct polls in this day and age.

I mean, Facebook ads???. I'm not even on Facebook, and I'd imagine a lot of the people who are have had their brains cooked! And even moreso for someone who clicks on an advertisement.

I really feel like what is needed is for text messaging to be improved by a lot before this stuff can be considered reliable. I want to actually know that the link I'm clicking on is from a trustworthy organization. But even then, there are probably differences in terms of who responds to polls.
