ADP reported January 2013 non-farm private jobs growth at 192,000. The market expected 175K (versus the 192K reported). These numbers are all seasonally adjusted.
- This month, ADP’s analysis is that small and medium sized business created the majority of the jobs.
- Manufacturing remains the headwind to employment gains
- trade / transport / utilities sectors provided almost 1/3 of the employment increase.
- This was the largest monthly job growth since February 2012.
- The December 2012 ADP jobs, which reported job gains of 215,000, was revised downward by 30,000 to 185,000 jobs
ADP had been the best real time indicator of jobs growth, and we are monitoring their current new methodology which began with their October 2012 report. Jobs growth has been over economic potential until recently – and now jobs growth is near potential.
Jobs growth of 150,000 or more is calculated by Econintersect to the minimum jobs growth to support population growth (see caveats below). The graph below shows ADP employment gains by month. A comparison between the ADP jobs estimates and the BLS estimates is in the caveats section below.
From the press release:
“U.S. private sector employment got off to a good start in 2013, as 192,000 jobs were added during the month of January,” noted Carlos A. Rodriguez, president and chief executive officer of ADP. “According to the ADP National Employment Report, private sector employers created an average of183,000 new jobs per month during the last three months. This is an encouraging sign of steady improvement in the job market.”
Mark Zandi, chief economist of Moody’s Analytics, said, “The job market is slowly, but steadily, improving. Monthly job gains appear to have accelerated from near 150,000 to closer to 175,000. Construction is finally kicking into gear and more than offsetting the weakness in manufacturing. The recent gains may be overstating any improvement, particularly in the context of recent revivals in growth at the start of the past three years, but the gains are encouraging nonetheless.”
Employment is a rear view indicator, and looking at this ADP data – the overall trend for the rate of growth had been slightly less good for 2012 – but relatively flat since mid-2010. (red line in graph below). The year-over-year jobs growth has been in a tight range of 1.6% to 1.7% for the last 4 months – but this month year-over-year jobs growth was less good at 1.5%. The rate of improvement of employment growth is less good.
ADP Non-Farm Private Employment – Total (blue line) and Year-over-Year Change (red line)
Small and medium sized business historically create most of the new jobs (analysis here) when using the ADP data. A continuing take from the ADP data is that small and medium size business continue to be the employment driver. However, the BLS totally disagrees (see caveats below). The current ADP methodology is showing more jobs growth in big business (and therefore less in small business). Likely they are slowly correcting their data base.
Ratio of ADP Under 500 person Business Growth to Total Business Growth
The relative strength is in the service sector which has driven the jobs growth in 2012. Manufacturing jobs contracted this month – and they have been up and down for six months.
The graph below breaks down employment growth by size of company.

This month large business created all the jobs.

In our November 2012 economic forecast released in late October, we estimated non-farm payroll growth at 140,000.
Finally, this is a breakdown by sector of contribution this month to employment.
Caveats on the Use of ADP Employment Data
Historically employment is the confirmation that real economic growth is occurring. As background, many economic factors impact jobs growth. How many jobs businesses create in any one month is not directly dependent on these economic factors, but on individual decisions. The impact of all the economic factors is averaged out over many months.
Here is the revised methodology beginning with the October 2012 data:
Working in close collaboration with Moody’s Analytics, Inc. and its experienced team of labor market researchers, the ADP Research InstituteSM has further enhanced the monthly ADP National Employment Report® in order to more closely align it with the final print of the U.S. Bureau of Labor Statistics (BLS) numbers.
Beginning with its November 1, 2012 report, the ADP National Employment Report’s new methodology now utilizes ADP payroll data, U.S. BLS employment data, and the Philadelphia Federal Reserve Bank’s Aruoba-Diebold-Scotti Business Conditions Index.
In addition, the sample size of the ADP data set from which the newly enhanced ADP National Employment Report is derived has been expanded from 344,000 U.S. companies to 406,000, and from 21 million employees to 23 million, which accounts for more than 20 percent of all U.S. private sector employees. This larger data set is expected to help enable the ADP National Employment Report to more closely match the final print of the BLS numbers.
According to the new methodology, Moody’s Analytics’ monthly analysis for the ADP National Employment Report begins with processing ADP data according to the following steps:
- Classification by industry and size class based on the North American Industrial Classification system (NAICS)
- Creation of matched pairs for employment during the pay period including the 12th of the month
- Seasonal adjustment
- Removal of outliers
- Adjustments are made to match the industry and size distribution to the Quarterly Census of Employment and Wages (QCEW) industry and size data reported each March
- Regressions are run to predict the current month’s BLS number by industry
- These are then aggregated to derive the growth in total nonfarm private employment
- Industry, size and total growth rate estimates are then converted into differences.
Additional information about Moody’s Analytics’ methodology can be found at ADPEmploymentReport.com.
Basically this employment index is designed to mimic BLS private non-farm employment – which does not include government employment. The headline BLS Employment Report includes government employment.
Econintersect believes the simplistic sampling extrapolation technique of ADP yields a far better picture of the employment situation in real time than Bureau of Labor Statistics (BLS) methodology. Although the BLS employment numbers eventually are correct, their data gathering technique does not support the quick release schedule.
Because of the differences in methodology, many pundits ignore the ADP numbers. Although there can be a low correlation in a particular month, the different methodologies tend to balance out, and the correlations are excellent outside of the data turning points. We are now 22 months past the post recession turning point in employment. Based on current estimates, BLS non-farm private jobs growth in 2011 was 1,920,000 while ADP was 1,925,000. The difference is insignificant. The graph below shows ADP’s monthly change (blue line) versus BLS non-farm private change (red line).
ADP versus BLS – Monthly Jobs Growth Comparison
There is now a known disconnect between BLS and ADP on the breakdown of jobs growth between small, medium and large business – as the graphs below illustrate. Basically the BLS sees large business as the employment driver, while ADP sees small and medium size business as the employment driver.

Comparing Jobs Growth Per Month – ADP vs BLS
There is the proverbial question on what is minimal jobs growth each month required to allow for new entrants to the market. Depending on mindset, this answer varies. According to Investopdia, the number is between 100,000 and 150,000. The Wall Street Journal is citing 125K. Mark Zandi said 150K. Econintersect is going with Mark Zandi’s number:
- If Econintersect used employment / population ratios to determine the number, the exact number seems to be between 140,000 and 160,000. The graph below uses the historical employment-population ratios to show jobs growth per month if the population was 300 million.
Historical Monthly Jobs Growth Comparison if Population was 300 Million
- If Econintersect uses employment – population ratios, the correct number would be the number where this ratio improved. Using the graph below, the ratio began to improve starting a little after mid-year. This corresponds to the period where the 12 month rolling average of job gains hit 150,000.
Employment to Population Ratio
Note: The ratio could be fine tuned by adjusting to the ratio of employment to working age population rather than the total population. However, this would not change the big picture that an increase of somewhere around 150,000 (+/-) is needed for the growing population numbers. We have estimated 140k – 160k. The number might possibly be within the range 125k – 175k. Econintersect cannot find reason to support the estimates below 125k.
The question of how changing demographics impact the employment numbers is at the margins of analysis. Econintersect will publish more on this fine tuning going forward, both in-house research and the work of others.
The following graph (not seasonally adjusted non-farm private payroll) shows that most of the employment growth are in the first half of the year, and there is little real growth of employment in the second half of the year. Therefore seasonal adjustment algorithms understate employment growth in the first half of the year, and overstate growth in the second half of the year.
