Census vs. Survey — What's the Difference?

In terms of coverage, a census seeks to reach every individual or unit within its target group. This comprehensive approach ensures that every entity is accounted for, yielding a complete data set. Surveys, conversely, gather data from a subset of the population, making generalizations about the entire group based on this sample.

The frequency of conducting a census and a survey can vary. Typically, censuses are taken at regular, longer intervals due to their expansive nature, such as every ten years in the case of the U.S. population census. Surveys can be more flexible, conducted as frequently as needed, depending on the research question or objective.

The type of data collected also distinguishes a census from a survey. While a census might focus on specific demographic data like age, gender, and occupation, surveys can cover a wider range of topics, from consumer preferences to opinions on social issues.

To summarize, while both a census and a survey are instrumental in understanding populations and trends, the breadth of coverage, frequency, and types of data collected set them apart. Both have their unique advantages, dictated by their specific goals.

A census and a survey are both valuable tools in data collection, yet they serve different purposes and employ distinct methodologies. A census is an official count, typically conducted by governments, aimed at enumerating every individual in a particular population. Surveys, on the other hand, are conducted on a sample of the population, not necessarily by governmental entities, to infer or deduce information about the larger group.
