Science and engineering degree share

Share of bachelor’s-or-higher adults age 25–64 with a science and engineering field of degree under the ACS/NSF definition (SCIENGP).

What this measure means

Share of bachelor’s-or-higher adults age 25–64 with a science and engineering field of degree under the ACS/NSF definition (SCIENGP). SCIENGP summarizes the bachelor’s fields reported in FOD1P/FOD2P. It includes social and behavioral sciences under NSF’s S&E classification and excludes SCIENGRLP-only fields. This is not a custom broad STEM-degree classification.

Who is included

Population (universe): Civilian noninstitutionalized population age 25–64 with a bachelor’s degree or higher and a valid SCIENGP flag
Age range: 25–64
Measure and unit: Rate; Percent
Denominator: people in universe

Uncertainty and reliability

When results are withheld: Results are withheld when fewer than 351 survey records are included in the denominator.
When to use caution: Results are marked unstable when the standard error exceeds 30% of the estimate's absolute value. This is the relative standard error (RSE). Use these estimates with caution.

Survey weights used: PWGTP and PWGTP1–PWGTP80
