The Business Register Bridge (BRB) is a link between LEHD employer<br />
microdata <strong>and</strong> Business Register (BR) firms, <strong>and</strong> establishment<br />
microdata. Since the concepts of “firm” <strong>and</strong> “establishment” differ<br />
between the LEHD employer microdata <strong>and</strong> the BR, the BRB provides<br />
a crosswalk at various levels of business-unit aggregation. The most<br />
detailed crosswalk is at the level of Employer Identification Number<br />
(EIN)—State-four-digit St<strong>and</strong>ard Industry Classification (SIC) Industry-<br />
County. The bridge includes the full list of establishments in the<br />
LEHD data <strong>and</strong> in the BR that are associated with the business units<br />
(e.g., EIN-four-digit SIC-State-County) in the crosswalk <strong>and</strong> measures<br />
of activity (e.g., employment, sales).<br />
The Employer Characteristics File (ECF) consolidates most firm-level<br />
information (size, location, industry, etc.) into two easily accessible<br />
files. The firm-level file has one record for every year <strong>and</strong> quarter in<br />
which a firm is present in either the covered Employment <strong>and</strong> Wages<br />
(ES-202) program data or the unemployment insurance system<br />
(UI) wage records. Firms are identified by the LEHD State Employer<br />
Identification Number (SEIN). The data in the firm-level file is aggregated<br />
from the core establishment-level file, where establishments<br />
are identified by reporting unit number within SEIN, called SEINUNIT.<br />
The Employment History File (EHF) provides a full time series of<br />
earnings at all within-state jobs for all quarters covered by the LEHD<br />
system <strong>and</strong> provided by the state. It also provides activity calendars<br />
at a job, firm <strong>and</strong> sub-firm reporting unit level. It can be linked to<br />
other <strong>Census</strong> <strong>Bureau</strong> files through the Protected Identity Key (PIK)<br />
<strong>and</strong> the LEHD SEIN.<br />
The Geocoded Address List (GAL) is a dataset containing unique<br />
commercial <strong>and</strong> residential addresses in a state geocoded to the census<br />
block <strong>and</strong> latitude/longitude coordinates. It consists of the GAL<br />
<strong>and</strong> a crosswalk for each processed file-year. The GAL contains each<br />
unique address, a GAL identifier, its geocodes, a flag for each fileyear<br />
in which it appears, data quality indicators, <strong>and</strong> data processing<br />
information. The GAL Crosswalk contains the GAL identifier.<br />
The Individual Characteristics File (ICF) for each state contains one<br />
record for every person who has ever been employed in that state<br />
over the period spanned by the state’s unemployment insurance<br />
records. It consolidates information from multiple input sources on<br />
gender, age, citizenship, point-in-time residence, <strong>and</strong> education.<br />
Information on gender, education, <strong>and</strong> age is imputed ten times<br />
when missing.<br />
