What Is a Survey Marker?

The investigation item is the specific content to be investigated. It is entirely determined by the nature of the object of the investigation, the purpose of the investigation and the task. Includes the signs (quality and quantity signs) and other relevant conditions that must be registered by the survey unit. For example, in the sixth national census of 2010, names, gender, age, ethnicity, education level, industry, occupation, migration, social security, marriage and childbirth, death, and housing conditions were prepared as survey items. ^[1]
