Jefferson, IN Internet Speeds — Measured 2024
Real speed tests run in Jefferson County, Indiana during 2024 recorded a median download of 71.0 Mbps, upload of 22.2 Mbps and latency of 34.8 ms, across 1,872 measurements. That is 0.8× the US median and places it #1,604 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 Jefferson came in below 71.0 Mbps and half above. The slower quarter of connections measured under 22.8 Mbps, while the faster quarter exceeded 140.6 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 71.0 Mbps down and 22.2 Mbps up, a typical household here can handle HD streaming and video calls, though simultaneous heavy use may compete for bandwidth. Latency of 34.8 ms is acceptable for most real-time use.
