Since the September employment report was not released as scheduled on Friday because of the government shutdown, CNBC crunched the numbers and the "Official Squawk Box Jobs Report" pegged nonfarm payroll growth at 158,000 jobs last month.

Again, this is not the Labor Department number that's usually released at 8:30 a.m. ET.

But CNBC's economic guru Steve Liesman did the analysis—saying he settled on his number in a similar fashion to the real government report.

The methodology? Liesman said he used historical data to estimate what four different indicators—jobless claims, ADP, ISM and NFIB—suggested about where nonfarm payroll growth should be.

For example, he took the ADP report released Thursday, which put private sector growth at 166,000 jobs, and bumped it up a bit to account for that number being a little light recently.

Liesman did the same for the three other indicators, and then took the average of all four—arriving at his estimate of 158,000.

Moody's Chief Economist Mark Zandi—who compiles the ADP report—said, "That's exactly how" government officials calculate the real number.
