An Assessment of the “All-In” Assumption for FCC 477 Data
Until recently, the only source for broadband availability data was the Form 477 data collected (since 2014) by the Federal Communications Commission. These data are collected by the FCC from broadband providers at the census block level (averaging about 20 homes). Under an “all-in” assumption, a census block is deemed to have broadband (at a specified speed threshold) if a provider serves (or could serve in a few months) a single location within the block. This assumption tends, of course, to overstate broadband availability.
