ITHACA, NY – A couple folks might be concerned this week after Jason Tillberg’s latest piece about Ithaca’s deflating economy. But there’s a caution light before this data is taken to be hard truth. Frankly, the BLS estimates suck.

A lot.

The numbers are subject to big revisions. Case in point, here are the pre-revision and post-revision 2013 and 2014 data:

It’s not uncommon for the numbers to be changed by thousands, because it’s based on a random sampling of non-government multi-person employers. 500,000 are sampled over the whole country each month, but only about 55 of the 3,300 or so oranizations in Tompkins and Cortland Counties are included in the Ithaca metro sample (Cortland’s jobs numbers are included with Ithaca’s because jobs are measured by Combined Statistical Area [CSAs].

However, Ithaca is considered a separate metropolitan area [MSA] from the Cortland micropolitan area [µSA], so population stats are always distinct). The overall trend of the selected orgs is then applied to a base number.

For places like Ithaca where the local economy is dominated by a few employers, random sampling isn’t the best approach because it misses crucial components of the local economic picture. But the BLS sticks with its current approach for consistency’s sake across regions and time periods.

During the first quarter of each year, the BLS conducts a full analysis and re-analysis of data going back the last three years. The general rule is, the data from three years ago is very good, the data from two years ago is okay, and the data from the previous year is…very, very preliminary. Tompkins County hasn’t had any large layoffs reported the state’s WARN database this year, and the only major retail closings recently have been A.C. Moore and Tim Horton’s.

In short, don’t let it keep you up at night, and wait until March before passing judgement on the 2015 economy.
