COVID-19 Forecasts: Deaths

COVID-19 Forecasts: Deaths
Updated Nov. 25, 2020

Observed and forecasted new and total reported COVID-19 deaths as of November 23, 2020.

Interpretation of Forecasts of New and Total Deaths

  • This week, CDC received forecasts of COVID-19 deaths over the next 4 weeks from 36 modeling groups that were included in the ensemble forecast. Of the 36 groups, 33 provided forecasts for both new and total deaths, two groups forecasted total deaths only, and one forecasted new deaths only.
  • This week’s national ensemble forecast predicts that the number of newly reported COVID-19 deaths will likely increase over the next 4 weeks, with 10,600 to 21,400 new deaths likely to be reported in the week ending December 19, 2020. The national ensemble predicts that a total of 294,000 to 321,000 COVID-19 deaths will be reported by this date.
  • The state- and territory-level ensemble forecasts predict that over the next 4 weeks, the number of newly reported deaths per week will likely increase in 39 jurisdictions, which are indicated in the forecast plots below. Trends in numbers of future reported deaths are uncertain or predicted to remain stable in the other states and territories.

National Forecast

  • The top row of the figure shows the number of new COVID-19 deaths reported in the United States each week from September 19 through November 21 and forecasted new deaths over the next 4 weeks, through December 19.
  • The bottom row of the figure shows the number of total COVID-19 deaths in the United States each week from September 19 through November 21 and the forecasted number of total COVID-19 deaths over the next 4 weeks, through December 19.
  • Models make various assumptions about the levels of social distancing and other interventions, which may not reflect recent changes in behavior.

State Forecasts

Plots of individual state forecasts, each state-level ensemble forecast, and the underlying data can be downloaded below. Each state forecast figure uses a different scale, due to differences in the number of COVID-19 deaths between states.

Ensemble Forecast

An “ensemble” forecast combines each of the independently developed forecasts into one aggregate forecast to improve prediction over the next 4 weeks. Both national- and state-level ensemble forecasts are developed for predicting new and total COVID-19 deaths reported each week for the next 4 weeks. Ensemble Forecasts of Coronavirus Disease 2019 (COVID-19) in the U.S.external icon describes its accuracy in short-term predictions and its usefulness as a real-time tool to help guide policy and planning.

Forecast Inclusion and Assumptions

The forecast included in the ensemble are displayed below. Forecasts are included when they meet a set of submission and data quality requirements, further described here: https://github.com/reichlab/covid-19-forecast-hub#ensemble-modelexternal icon.

The forecasts make different assumptions about social distancing measures. Information about individual models is available here: https://github.com/cdcepi/COVID-19-Forecasts/blob/master/COVID-19_Forecast_Model_Descriptions.mdexternal icon. The list below includes all models that submitted a national- or state-level forecast.
