Purpose of survey regarding research and analysis

In research of human subjects, a survey is a list of questions aimed for extracting specific data from a particular group of people. Surveys may be conducted by phone, mail, via the internet, and also at street corners or in malls. Surveys are used to gather or gain knowledge in fields such as social research and demography.

Survey research is often used to assess thoughts, opinions and feelings.[1] Surveys can be specific and limited, or they can have more global, widespread goals. Psychologists and sociologists often use surveys to analyze behavior, while it is also used to meet the more pragmatic needs of the media, such as, in evaluating political candidates, public health officials, professional organizations, and advertising and marketing directors. Survey research has also been employed in various medical and surgical fields to gather information about healthcare personnel’s practice patterns and professional attitudes toward various clinical problems and diseases. Healthcare professionals that may be enrolled in survey studies include physicians,[2][3] nurses,[4] and physical therapists[5] among others. A survey consists of a predetermined set of questions that is given to a sample.[1] With a representative sample, that is, one that is representative of the larger population of interest, one can describe the attitudes of the population from which the sample was drawn. Further, one can compare the attitudes of different populations as well as look for changes in attitudes over time. A good sample selection is key as it allows one to generalize the findings from the sample to the population, which is the whole purpose of survey research. In addition to this, it is important to ensure that survey questions are not biased such as using suggestive words. This prevents inaccurate results in a survey.

Types
Census
Main article: Census
A census is the procedure of systematically acquiring and recording information about the members of a specific given population. It is a regularly occurring and official count of a particular population.[6] The term is used mostly in connection with national population and housing censuses; other common censuses include agriculture, business, and traffic censuses. The United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every 10 years

Other household surveys

Other surveys than the census may explore characteristics in households, such as fertility, family structure, and demographics.

Household surveys with at least 10,000 participants include:
