Clayton, IA Internet Speeds — Measured 2024
Real speed tests run in Clayton County, Iowa during 2024 recorded a median download of 39.7 Mbps, upload of 11.8 Mbps and latency of 27.8 ms, across 628 measurements. That is 0.5× the US median and places it #2,160 of 2,425 US counties.
What these numbers mean here
The median is the typical connection, not the best one available. Half the tests in Clayton came in below 39.7 Mbps and half above. The slower quarter of connections measured under 20.5 Mbps, while the faster quarter exceeded 73.4 Mbps — a spread that usually reflects a mix of fibre, cable and older DSL lines in the same area rather than one uniform service level.
At 39.7 Mbps down and 11.8 Mbps up, a typical household here can manage standard streaming and browsing, but will feel the limits with multiple users or large uploads. Latency of 27.8 ms is acceptable for most real-time use.
