What is the Difference Between Census and Survey?

🆚 Go to Comparative Table 🆚

The main difference between a census and a survey is the scope of the data collection:

  1. Census: In a census, data is collected from every member of a population, ensuring accurate and detailed information representative of the entire population. For example, the Census of Agriculture is a complete count of every known and potential agricultural operation and producer in the United States.
  2. Survey: In a survey, data is collected from a sub-part of the population, called a sample. The sample is used to estimate the characteristics of the whole population, and it is essential to ensure that the sample is representative of the population in question. Surveys can focus on finding different topics and information, such as opinions, behaviors, and consumer preferences.

In summary, a census gathers information from every entity in a population, while a survey collects data from a selected subset of the population. Both methods have their advantages and applications, and the choice between them depends on the goals, analysis needs, and available resources for the specific project.

    Frequency Occurs every 10 years (for a decennial census) Occurs at regular intervals, but not as frequent as a census
    Data Quality More accurate and reliable due to larger sample size Less accurate and reliable due to smaller sample size
    Information Collected Demographic, social, economic, and housing data Depends on the survey's purpose and focus
    Confidentiality Protected by law, data is anonymized Depends on the survey's confidentiality policies
    Accessibility Publicly available data Publicly available data, may require some knowledge to access

    In summary, a census is a comprehensive count of an entire population, while a survey is a gathering of information on a specific topic or population. Censuses are more accurate and reliable due to their larger sample size and coverage of the entire population, whereas surveys may vary in accuracy and reliability depending on their scope and sample size.
