I was tired of the media only reporting total cases, it's meaningless for me. 500 new cases in Nevada is significant, 500 in California is not.
I want to know the probability of meeting someone in the grocery store with coronavirus. To get that I need the Attack Rate, how many people are infected per 100,000 population. I started with Northern California where I live, but have expanded to include national and international data.
Note: Media is doing a better job of reporting rates so I don't have to do my own calculations in most cases.
Some data only updated every several weeks.

Objective:
I was tired of the media only reporting total cases, it's meaningless for me. 1,000 new cases in Nevada is significant, 1,000 in California is not.
I want to know the probability of meeting someone in the grocery store with coronavirus. To get that I need the Attack Rate, how many people are infected per 100,000 population.
I have gone thru several iterations concentrating on death rates in the beginning because of the lack of testing.

Joshua SA. Weitz at Georgie Tech developed a tool to assess the risk that one (or more) individuals in a group was infected which was documented in nature research in October.
. You specify the group size and an ascertainment bias of 5 or 10. i.e. actual infections are 5 to 10 times higher than what is reported.
See COVID-19 Event Risk Assessment Planning Tool
and Substantial underestimation of SARS-CoV-2 infection in the United States | Nature Communications Sept 2020.

We are concentrating on trends now from the world down to some towns in California. Where are the outbreaks, relative size of the them, history of safety plans etc..
Also listing death rates, hospitilazions and positivity rate where possible.

Test Positivity Rate
Experts advise looking at three measurements together: number of cases, case positivity rates and number of deaths to understand what is going on.
Test Positivity Rate is important because a high positivity rate probably means that the case count is low. See Positivity Rate.
WHO guidelines want it to be below 5%. When a positivity rate is higher, epidemiologists start worrying that means only sicker people have access to tests and a city or region is missing mild or asymptomatic cases.

United States Coronavirus: - Worldometer

COVID has been the third leading cause of death in the United States:

Provisional Death Counts for Coronavirus Disease 2019 (COVID-19) | CDC
The average percent of COVID-19 deaths from Mar. 21, 2020 to May 22, 2021 was 14.4%.
That made it #3 behind heart disease (28%) and cancer (25%) as cause of death.
Note: These are the 2019 rates for heart disease and cancer.
They may be lower in 2020 because people weakened from these diseases may have succumbed to COVID first. I don't know how the CDC counts someone who dies of heart disease because of stress from COVID.
See Cause of Death

1918 Flu:
Note: It was called the Spanish Flew because Spain was neutral in WWI so had not imposed wartime censorship on pandemic news like other countries, so were able to report on it.
One theory has it starting on American soil, in Kansas, where it migrated from birds to humans..

1. Fatality rate is difficult to measure because infections are difficult to count and the 1918 death toll varies.
2. Other estimates for the 1918 death toll range from 7 million to 100 million.
I think the rate in the chart below should be per Million not per 1,000. The American Lung Association has the same chart.
But "Comparison of Estimated Excess Deaths in New York City During the COVID-19 and 1918 Influenza Pandemics" | JAMA Network shows the peak in New York city to be similar for the flu and COVID-19.
It still doesn't add up 20 new cases/million/day x 10 ½ months would be 657,500 total cases in the US, but the average cases/day according to this chart would be less than 20.
Why the Second Wave of the 1918 Flu Pandemic Was So Deadly - HISTORY says 195,000 died in the US in October; That would be an average of 63 per million per day.

Some of the early talk about flattening the curve during COVID-19 may have came from this comparison of Philatelphia vs St. Louis during the 1918 flu.

The epicenters keeps changing:
The first confirmed case relating to the COVID-19 pandemic in the United States was announced by the state of Washington on January 21, 2020. Washington made the first announcement of a death from the disease in the U.S. on February 29 Washington had the highest absolute number of confirmed cases (500) and the highest number per capita (7 cases per 100,000)of any state in the country, until it was surpassed by New York state on April 10.

I moved back to California from New Jersey a couple of years ago. In April my friends in New Jersey had 10 times the chance of encountering a person with COVID-19 than I did in California. In July the numbers have flipped with California having 6 times and Florida 12 times the incidence of NJ.
By the end of November the average rate for the whole country was 5 times higher than it was in April.

Orange Tier: What's open.
The Red Tier:
According to California's Blueprint for a Safer Economy, the red tier opens up the possibilities for more things to do in a county. However, the red tier also means there is still "substantial spread" in the county. There are between four and seven new daily cases per 100,000 residents, or between 5% to 8% testing positivity rate. What restrictions are relaxed? What's still closed?
Holiday surge:

The increase of infections after holidays confirms the dangers of personal social gatherings.
There is a drop in infections durring the holidays because of reduced testing. Johns Hopkins University reported a high of more than 2 million tests a few days before Thanksgiving as people prepared to travel, but that number had dropped to less than 1.2 million tests on Thanksgiving Day.

Rational:
I started counting cases, but at the advice of my, Son, a medical journal editor, I changed this to report deaths which is likely more accurate than cases.
Case numbers are under reported because of a lack of testing, pre-symptomatic, and non-symptomatic people, which vary by location.
There are issues with death counts too, but fewer than with case counts.
See Deaths vs Cases.
After the Surge in the Southwestern US at the end of June, I started counting cases again, because of better testing and the 2 week lag between cases and deaths. Also the death rate is going down,

  There are other measurements that would be helpful in understanding the progress of the epidemic in different places, such as the number of new hospitalizations, the number of tests administered or the number of people showing any symptoms of respiratory illness. But confirmed coronavirus cases and deaths, however incomplete, are the most useful daily statistics currently available at a local level everywhere in the country.
Hospitalizations and deaths lag cases by one to two weeks.
