This table provides metadata for the actual indicator available from US statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from US statistics, this table should be consulted for information on national methodology and other US-specific metadata information.
|Actual indicator available
|Percentage of the U.S. population covered by at least a 3G mobile network. Percentage of the U.S. population covered by at least a 2G mobile network.
|Actual indicator available - description
|The definitions for the FCC indicators are: (1) percent of population covered by 3G or faster service, and (2) percent of population covered by 2G or faster service; where "3G" and "2G" have esssentialy the definitions given above. "Coverage" here indicates that at least one operator can provide a signal above the required m1nimum, but it is not necessarily true that at least one operator is actually offering service at that speed.
|Date of national source publication
|September 2017, releasing year-end 2016 data.
|Method of computation
|Scheduled update by national source
|U.S. method of computation
|Three methods were employed over this time period. 2015-2016: "Form 477" data and "centroid" computation method. 2007-2013: data from American Roamer (company renamed Mosaik as of 2011 data) and "centroid" computation method. 2000-2005: entire county treated as covered if any coverage in county. Population data from most recent U.S. census available.
|Comments and limitations
|The FCC’s annual report, the Mobile Wireless Competition Report, prepared by the Wireless Telecommunications Bureau, usually includes the most recent year's data on 3G+ and 2G+ coverage, either in the body of the report or in its associated web appendices and "quick facts." These two time series were created by pulling data from the 6th through 20th annual reports. Note the three different data/computation methods used over this period, as described above. Other notes: (1) 2G+ coverage often appears in the reports simply as total mobile coverage, since "2G or faster" captures all digital air interfaces, and (1G) analog service is no longer offered. (2) Since the measures are 3G or faster and 2G or faster, it is the gap between the two figures that gives the coverage of 2G only, or narrowband, service. (3) Percentages are shown rounded to one decimal place, as presented in the public reports. (4) "n/a" indicates "not available."
