WASHINGTON, Feb 9 (Reuters) – White House economic adviser Kevin Hassett said on Monday that ​Americans could see smaller job growth ‌numbers in the coming months due to lower population figures ‌and higher productivity.

The combination of strong GDP growth and a pretty big decline in the labor force “because of illegals leaving the country” could ⁠lead to lower ‌job numbers, Hassett, director of the National Economic Council, said in an ‍interview with CNBC.

“So I think that you should expect slightly smaller job numbers that are consistent with high ​GDP growth right now,” Hassett said.

“And that ‌one shouldn’t panic if you see a sequence of numbers that are lower than you’re used to, because, again, population growth is going down and productivity growth is skyrocketing. It’s an ⁠unusual set of circumstances.”

The ​Labor Department is scheduled to ​report the delayed employment report for January on Wednesday. Nonfarm payrolls likely increased by ‍70,000 jobs ⁠last month, a Reuters survey of economists showed, after rising 50,000 in December.

The U.S. ⁠unemployment rate was 4.4% in December. Economists polled by ‌Reuters expect it will be unchanged for ‌January.
