Summary of differences

The restricted-use file may include lower-level geography and select variables not available on the public-use file due to possible disclosure risk. Most restricted-use geographic NCHS variables can only be used to merge external data or to categorize geographic areas with similar characteristics. Researchers should not estimate regions smaller than the specific survey's sample design would support, even when smaller levels of geography are available.
