Quarterly Census of Employment and Wages

Employment, wages, and establishment counts in hurricane flood zones

Latest Storm Information

Hurricane Idalia

Hurricane Idalia The Quarterly Census of Employment and Wages (QCEW) program has created a set of maps and data for hurricane flood zones on the Gulf and Atlantic Coasts. Where permitted by State regulations, maps include dots indicating the location of business and government establishments. This product is the combination of geocoded BLS establishment data and flood zones created by the U. S. Corps of Engineers and State emergency management authorities. For more information, see the flood zone Questions and Answers page.

The summarized data are presented for each zone. If a Category I storm is experienced, the subject establishments are represented by the zone 1 sums. The zone 2 sums represent the establishments which are not affected by Category I storms, but are affected by Category II storms. To get a total for establishments subject to a Category II storm, users should add the zone 1 and zone 2 values. The zone 3 sums represent the establishments which are not affected by Category I or II storms, but are affected by Category III storms. To get a total for establishments subject to a Category III storm, users should add the zone 1, 2, and 3 values. The zone 4 sums represent the establishments which are not affected by Category I, II, or III storms, but are affected by Category IV storms. To get a total for establishments subject to a Category IV storm, users should add the zone 1, 2, 3, and 4 values.
