A sample revision is the process used to re-design and re-select the samples for many of the Census Bureau’s surveys of the retail, wholesale, and service industries. This process is performed to:
- ensure each sample is representative of its target population
- improve the efficiency of each sample
- incorporate updates to the industry classification structure
- expand industry coverage of the survey
- update questions and instructions to obtain more accurate data
- redistribute burden for small and medium size businesses
Sample revisions are performed approximately every two and a half to three years.
