Not the Parent but the orignal numbers come form the CDC but I'm not sure where the graph is from. Here are links to the last two years of data, embedded in a comment I made on HN recently:

From the CDC: In 2019, a total of 2,854,838 resident deaths were registered in the United States—15,633 more deaths than in 2018. In 2020, approximately 3,358,814 deaths occurred in the United States (Table). The age-adjusted rate was 828.7 deaths per 100,000 population, an increase of 15.9% from 715.2 in 2019.

Here is the one I look at (might need desktop version), https://www.cdc.gov/nchs/nvss/vsrr/covid19/excess_deaths.htm

It was generated from the CDC data available here: https://gis.cdc.gov/grasp/fluview/mortality.html
