The CDC updated its variant prevalence estimates this week, reporting that the Delta variant makes up 10% of U.S. cases as of June 5. This aligns with other estimates I cited last week, and suggests that the variant is spreading here at a truly rapid pace—its prevalence multiplied by four times in two weeks, according to CDC data.
Since early January, the COVID-19 Data Dispatch has maintained a page of detailed annotations on all the major sources for vaccination data in the U.S. This includes government sources (the CDC, all 50 states, and D.C.), along with a few notable news publications and independent dashboards.

Excess deaths are those deaths that occur above a region’s past baseline. Data scientists calculate the metric by determining the average deaths for a country or region over a period of several years—then comparing this past average to the deaths that occured in the current year. The deaths occurring in the current year above that […]
