Dataset contains US Department of Labor Bureau of Labor Statistics’ monthly data on changes in the US Total Non farm Payrolls and revisions of estimates since 1979.
Non farm payroll employment is a compiled name for goods, construction and manufacturing companies in the US. It does not include farm workers, private household employees, or non-profit organization employees. It is an influential statistic and economic indicator released monthly by the United States Department of Labor as part of a comprehensive report on the state of the labor market. The NFP number is meant to represent the number of jobs added or lost in the economy over the last month, not including jobs relating to the farming industry.
The Bureau of Labor Statistics releases preliminary data on the third Friday after the conclusion of the reference week, i.e., the week which includes the 12th of the month, at 8:30 a.m. Eastern Time; typically this date occurs on the first Friday of the month.
Payroll refers to the payroll for full- and part-time workers who received pay for any part of the pay period that includes the 12th day of the month. The payroll is reported before deductions of any kind, such as those for old-age and unemployment insurance, group insurance, withholding tax, bonds, or union dues; also included is pay for overtime, holidays and vacation, sick leave paid directly by the firm, and commissions paid at least monthly. Bonuses (unless earned and paid regularly each pay period); other pay not earned in the pay period reported (such as retroactive pay); and the value of free rent, fuel, meals, or other payment in kind are excluded. Employee benefits (such as health and other types of insurance, contributions to retirement, and so forth, paid by the employer) also are excluded.
The data comes Current Employment Statistics (CES) and have been revised by the BLS typically by one and two months after the preliminary release. First preliminary estimates of employment, hours, and earnings, based on less than the total sample, are published immediately following the reference month. Final (third) revised sample-based estimates are published 2 months later when nearly all the reports in the sample have been received.
Revisions to CES over-the-month changes are calculated by comparing each month's second preliminary over-the-month change to the first preliminary over-the-month change, the final sample-based over-the month change with the second preliminary over-the-month change, and the final sample-based over-the-month change to the first preliminary over-the-month change.
