Hispanic and Asian workers are largely responsible for labor force growth especially since the mid 2000s.

The Hispanic share of the labor force will grow from 9.1% in 1994 to 19.8% in 2024. Its numerical growth from 2004 to 2024 will be 69%. Asian share will from 4.2% in 1994 to 6.6% in 2024. Its numerical growth from 2004 to 2024 will be 72%. But the size of the white non-Hispanic labor force will absolutely decline from 2004 to 2024 by 4%. The black labor force will increase from 2004 to 2024 by 25% but by 2024 will be less than half the size of the Hispanic+Asian workforce.
