The payments are deposited monthly or semiweekly (for employers with large payroll) but that's a lump sum. If you are looking at that from the government side all you can tell is whether total payroll has gone up or down. That won't tell if any change is due to a change in number of employees or a change in pay rates or some combination of that.

It isn't until the employer files their quarterly Form 941 that you'd see employment numbers. Form 941 includes the number of employees and total wages and withholding.

It isn't until the annual W-2 filings that you would see a breakdown that includes number of employees and the individual pay.

Ah okay, this is why then. So all my other comments complaining about the lack of timeliness have this simple explanation. TIL
