Description

SAMPFRCT indicates the average sampling fraction for the census or survey. This sampling fraction corresponds to the overall proportion of the country's population included in the sample, which may have actual variability for subpopulations or by geography.

The most common fraction for census samples is a flat (constant) 10% of the population. Users can refer to the sample information page and to the variable SAMPMETH to learn more about the sample design and whether sample fractions may vary across the country.

Comparability — Index

Comparability — General

The variable is generally comparable across samples, with the caveat that it could differ for specific subpopulations.
