How are businesses selected for the monthly and annual surveys?

Businesses are categorized by their industrial activity and size. Within each of these groups, the Census Bureau selects a random sample of firms. Each quarter, new businesses undergo a similar procedure, and additional sampling units are selected and added to the survey. This methodology ensures that the sample contains businesses of all sizes and from each retail industry.
