A pollster is a professional who conducts public opinion polls, which are surveys designed to collect information about what people think or feel about certain issues. Pollsters use various methods such as phone calls, online surveys, and face-to-face interviews to gather data from a representative sample of the population. They then analyze this data and publish their findings in order to provide insights into public opinion on current events, political campaigns or other topics of interest. Pollsters often work for research firms, news organizations, or polling companies that provide information to businesses, non-profits, or government agencies.
