Looking a Raj's variants dashboard…
For August, Colorado (with a population of 6 million) was the source of more variant sequences to GISAID than California (with six-and-a-half times the population).
Colorado sourced three-and-a-half times as many sequences to GISAID as did New York, despite New York having over three times the population of Colorado.
Meanwhile, Utah, with a population of only three-and-a-half million, provided more sequences than dozens of states with larger populations, including not only New York, but such other Democrat trifecta states as Oregon, Maryland, New Jersey, Washington, Illinois, Connecticut and Massachusetts—all with larger populations than Utah.
GISAID, here, is a proxy for data being received by the #CDC. They've switched to "empiric proportions" reporting because they don't have enough data to build historical models from.
This being a problem that started during prior administration, when CDC would regularly publish regional maps with no data.
