Sense: noun/1
For noun sense 1, poll usually means a structured check of what people think at a particular time, often by asking only a sample of the whole group. Survey is broader: it can study habits, experiences, or facts as well as opinions, and it is often longer. A questionnaire is the actual list of questions or form that people answer, not the whole research activity. A census is much larger because it aims to count or ask every person in a population, not just a sample. A straw poll is informal and quick, often used to test opinion before a final choice. A TV station may run a poll, a school may conduct a survey, a clinic may hand out a questionnaire, and a government carries out a census.
Etymology
Poll came into English in the Middle English period, probably from a Low German source. Its earliest meaning was 'head'. From the idea of counting heads, English developed uses for counting people, then votes in an election, and later the modern sense of asking a sample of people what they think.
