Hurricane impact on CES‐SA Benchmark 2017

A series of hurricanes struck Florida, Texas, Puerto Rico, and the U.S. Virgin Islands in August and September 2017, complicating the post-benchmark (October-December 2017) re-estimation process for these areas. Hurricane Harvey made landfall on the Texas Gulf Coast in late August. The population counts obtained from QCEW indicated that the September CES sample-based estimates suitably captured the employment drops associated with this event. No modifications were made for Texas October or November re-estimates, which saw corresponding returns in employment.

Hurricane Irma hit Florida just prior to the September reference period for many establishments. The benchmark data showed a much larger decline in September than the CES estimates did. A large part of this discrepancy was attributed to a spike in employment loss associated with business deaths, although there was information that many of these establishments returned to normal operation prior to October. Consequently, establishments which reported positive employment to the CES survey in August and October, and zero in September, were used in the Florida October re-estimates matched sample, a modification of the standard handling of business births and deaths. In the same fashion, a small number of establishments that reported they were shut down through the October reference period but reported positive employment in November were used in November’ s matched sample.

Hurricane Irma also struck Puerto Rico, although job losses there were more evident in October following the destruction caused by Hurricane Maria. Modifications were made to the birth/death procedure for re-estimates in Puerto Rico as well, to use reported zero employment for establishment deaths attributed to the storm in the October matched sample, and to use returning units in November and December. This procedure was also used when making the initial sample-based estimates for October through December.

The U.S. Virgin Islands showed large job losses in the aftermath of both Irma and Maria. No modifications were made to the re-estimation procedures for the U.S. Virgin Islands, which uses a quota-based sample design that differs from the rest of the CES program.
