The economy added just 74,000 payrolls in December.
Part of the noise came from unusually low temperatures - as a result of which, 1.7 million workers took part-time instead of full-time jobs.
That's according to Mesirow Financial economist Diane Swonk:
Weather: 1.7 mil took part-time instead of full-time bc weather

The number of persons employed part time for economic reasons (either because hours were cut back or they couldn't find full-time work) was essentially unchanged at 7.8 million. These individuals were working part time because their hours had been cut back or because they were unable to find full- time work.
BI's Sam Ro has the full breakdown of what weather may have done to the numbers.
To be sure, weather can't explain all the other bad stuff going on. But it's something to keep in mind.
