The average available internet speed is measured as the average of the maximum advertised commercial internet speeds available to households in each census block in the County. The data on commercial internet availability come from the Federal Communications Commission (FCC), which requires internet providers to report advertised speeds delivered within each census block in the U.S. Where multiple providers offer service, the highest speed was used to calculate the average for all census blocks, using the number of households in the block as a weighting factor.
