FDA's Food Safety and Nutrition Survey (FSANS)

FDA's premier, national probability consumer survey designed to elicit consumers' knowledge, understanding, and reported behaviors on a variety of food safety and nutrition-related topics.

This application can be used to display survey question and demographic frequencies, and to run chi-square tests of independence, by using the “Frequencies” tab.

Several questions in FSANS are multi-part (i.e., grid) questions. These questions can be visualized as a bar chart by using the “Multi-part Questions” tab.

Note: Please zoom your browser if needed. Mozilla Firefox or Google Chrome is recommended for the best user experience.

Advanced Features

These features are for users who are already familiar with survey sampling and the FSANS data.

Sampling Weights

The weighted option (recommended) uses sampling weights (the reciprocal of selection probability) and takes survey design into account. Weights are also adjusted for non-response. The unweighted option does not use sampling weights. This option helps you assess the impact of sampling weights on the results. In most cases, the unweighted and weighted results will be fairly similar.
