12 economic code change indicator ecci
Economic Code Change Indicator (ECCI) (IMTQ-ECON-CODE-CHG-IND(1))
The current quarter economic code change indicator is a 2-byte, generally numeric composite field found in locations 720 and 721. Like the Field Locks indicator (IMT-FIELD-LOCK, described on page 19), this is a "pseudo-binary" representation, using the decimal values of binary digits (1, 2, 4, 8, 16, and 32) in a summed numeric notation to show any combination of economically-based changes to key quarterly fields. Those codes that require an economic basis for mid-year (defined as second through fourth quarter, or April through December) alterations include the NAICS (value = 32), county (value = 8), ownership (value = 4), and New England township (value = 1) codes. Originally, the SIC code (value = 2) and the NSTA code (value = 16) were also listed as valid values. Those are now ignored, however, since NSTA and SIC changes carry no economic weight.
Warning: The ECCI values used in the Micro File record are not identical to the ones found in the IMT record. When the NAICS became NSTA, the Aux-NAICS became NAICS, and SIC and NSTA were no longer considered refiling-related fields, the SIC’s value (2) was transferred to the NAICS code so that the range of values in the micro field is 00 through 15. In the above sample, the county and NAICS changes would have a value of 10 (8 + 2).
The numeric values involved in economic code changes are summed to produce the quarter's economic code change indicator. For example, a combined change to the county (8) and NAICS (32) codes will have an economic code change value of 40 (or 8 + 32).
The determination of the economic significance of a code change is made by the QCEW-unit analyst, rather than by any algorithmic calculation. The code change must take place over a 30-day time span and be discovered in time to include it with the quarterly deliverable. Because these are manual determinations, it is best to leave this field set to low-values unless economic significance of code changes has been stored elsewhere to make a clear and unambiguous field setting possible. Any values entered into this economic code change indicator on the IMT record will also be incorporated into the corresponding field in the Micro File (except for the 32 to 2 NAICS change mentioned earlier). However, when an economic code change is claimed, it will be verified in on-line Micro File checks whenever the account is called up for display. If an economic code change was claimed, but the identified field has not been modified, the setting will be removed.
