2003 Sample Size for Counties and County Equivalents Published

In the table below:

  • the column "number in sample" is the 12 month sample for the American Community Survey. The "number in sample" includes:
    • interviewed housing units,
    • deletes (addresses which had been misclassified as housing units or demolished units),
    • noninterviewed housing units and
    • housing units that were subsampled out.

  •  
  • the "number of interviews" is the actual sample that is used to produce all weighted estimates for the survey year. The number of interviews includes both occupied and vacant housing units. For example, a sampled case that refuses to answer the survey (a noninterview) would be in the sample but would not be an interview. Similarly a sampled case that turns out to be a business address would be a sampled case (a delete), but would not be an interview.
