That’s why an
item posted April 9, 2013 by the MacIver Institute caught our attention.
That’s a much larger number of jobs created under Walker than we’ve ever heard -- even from the governor himself.
In December 2012, Walker said the state had created "just under 100,000 jobs" since he took office. We rated that statement
Pants on Fire.
Why?
Walker had combined full and partial year data sets from the Quarterly
Census of Employment and Wages compiled by the federal Bureau of Labor
Statistics. His staff explained that he was using a "raw number."
But state experts and the governor’s own staff have long said that
while the quarterly census is more accurate than monthly measures, the
census data should only be viewed in one-year blocks. That is, January
to January, or July to July. In other words, you can’t combine partial
years of census data with full years to create a running total, due to
major seasonal fluctuations in the workforce.
Here is what Walker spokesman Cullen Werwie told us when we asked about
job numbers in the summer of 2012: "Please don’t, as John Koskinen, an
economist at DOR would say, compare February temperatures to July."
When we asked MacIver to show us their math, spokesman Nick Novak responded:
"We used Bureau of Labor Statistics QCEW figures for each month from
January 2011 to September 2012 (the most recent month available). To
get to the number of 137,372, we simply subtracted the January 2011 jobs
number from the September 2012 jobs number."
Novak provided a link to
a BLS report that showed the two numbers.
But, this isn’t just a simple math problem. MacIver made two critical errors in their calculations.
Starting point
Walker took office at the beginning of January 2011. MacIver used the
number for the end of January 2011. To properly measure the governor’s
promise, you need to start with the number of jobs that existed at the
start of his term. That is a difference of 65,401 jobs.
Here’s how it plays out the way the MacIver Institute calculated the numbers.
January 2011 census number: 2,205,584
September 2012 census number: 2,342,956
Increase: 137,372.
Here’s how it plays out with the December 2010 number.
December 2010 census number: 2,270,985
September 2012 census number: 2,342,956
Increase: 71,971
In summary: MacIver’s math nearly doubles Walker job count because it
started counting one month later. In effect, they used a lower starting
point, which makes the growth seem larger -- by 65,401 -- than it really
is.
And even that is a bad number.
Apples to oranges
There’s a second, more important -- and more familiar -- problem. Like
Walker in December, MacIver failed to line up a year-to-year
comparison. It measured February temperatures against July.
What’s more, the item itself notes that Koskinen, the state economist,
told them they should not combine the data sets in this manner:
While Koskinen called the numbers "literally true" the article goes on
to note: "Koskinen said economists typically use the same month from
different years to avoid seasonal variations in employment."
The MacIver Institute posted an item that says Wisconsin has 137,372
more private sector jobs than when Gov. Scott Walker first took office,
meaning that Walker is more than halfway to his goal of 250,000 jobs.
The jobs promise will be the No. 1 yardstick used to measure Walker’s performance as governor.
But the conservative group’s number is wrong, two times over.
MacIver started with the wrong month of data. That alone nearly doubled
the number of jobs they claim were created under Walker.
They compounded their error by combining full and partial years of data
-- even though they (like the governor himself) were told not to do so.
