WIRELINE COMPETITION BUREAU ANNOUNCES CONVERSION TO2010 CENSUS TRACTS FOR BROADBAND SUBSCRIBERSHIP
REPORTING IN FUTURE FCC FORM 477 FILINGS
WC Docket No. 07-38The Commission requires facilities-based wired, terrestrial fixed wireless, and satellite broadband
service providers to report on FCC Form 477 the number of broadband subscribers they have in each
census tract they serve.1 The Census Bureau changed the boundaries of some census tracts as part of the
2010 Census. This public notice announces, in response to informal inquiries from broadband service
providers, that broadband service providers must use the revised census tracts (i.e., the 2010 census tracts)
to report broadband subscribership information in the FCC Form 477 filing that is due no later than
March 1, 2012. That filing will collect information about the filers’ operations as of December 31, 2011.
Broadband service providers also will use the 2010 census tracts in subsequent FCC Form 477 reports
pending further revisions in census tract boundaries by the Census Bureau.
This is a change from earlier Form 477 filings in which entities reported broadband
subscribership information using the census tract boundaries that the Census Bureau employed in the
FORM 477 FILING SYSTEM MODIFICATIONSTo facilitate the transition to reporting based on the 2010 census tracts, the Wireline Competition
Bureau staff is modifying the Commission’s Form 477 electronic filing system. These modifications will
be largely transparent to filers.
For submissions of information as of December 31, 2011 and subsequent data-collection
dates, the system will recognize as valid only the census tract codes that were valid for
the 2010 Census.
For revisions of information as of June 30, 2011 and earlier data-collection dates, the
system will continue to recognize as valid only the census tract codes that were valid for
the 2000 Census.

Further Notice of Proposed Rulemaking, 23 FCC Rcd 9691, 9695-97, paras. 10-12 (2008) (2008 Broadband Data
Gathering Order). Although facilities-based mobile broadband providers report subscribership by state, they are
required to identify the census tracts that best represent their broadband service footprint for each of the speed tiers
in which they offer service. Id. at 6998, para. 16.
