Okay yeah but
FCC data is zoomed out, by nature. Rather than provide information on a household level, it offers data for census tracts. If you’re studying city neighborhoods — say you’re trying to figure out how internet use in poor neighborhoods is different from in rich ones — this lack of granularity can be a problem.
It's not like census tracts are huge. The grocery store (which my 5-year-old daughter has walked to several times) is in a different tract. Her school, which she has also walked to, is in yet another. Her old daycare, which we have also walked to, is in yet another. It's disingenuous to suggest that TIGER data isn't granular enough to cover neighborhoods; they're sized for accurate population measurement.
