Original post made on Mar 31, 2020

Can more be said on theories why we are increasing higher than other counties?

I would like to see stats: ages, male, female, race, etc.

Everything is a just a quick snapshot in time of an ever changing picture.
SCC was about two weeks ahead of SMC when this all started.
Wait two weeks and the chart will look different. SMC will catch up and SCA will hopefully be trending down.

I'm not sure that this is the correct way to look at these data. By plotting on a scale by day (X-axis), the fact that the "seeding" of the virus could have been at different times in the two counties is ignored and thus incorrect. This is borne out by the fact that Santa Clara's first case was on Jan 31 and San Mateo's was on Mar 2. What matters for spread in the community is once seeding takes place. If you look at the San Mateo plot and move it to the left about five days, it is almost the same shape and slope characteristics as the Santa Clara plot, indicating that the spread rate isn't all that different in the counties, just that the initial seeding was earlier in Santa Clara.

The graph of absolute counts isn't really a good comparison. San Mateo population is 760K people. Santa Clara population is 1.9M people. So it's not surprising if the count for Santa Clara is 2.5x that of San Mateo.

Amazed at how poor our so-called experts lack statistical skills other than being able to graph data using excel. A proper graph should be stated in terms of per capita to control for population differences. A betta comparison of curves would adjust the starting dated in order to compare the process across areas.

The headline implies that the two counties are comparable. Santa Clara County is not at all comparable to San Mateo County. SCC county with pop of 2M includes city of San Jose, 3rd largest city in CA (Pop. over 1M). SCC is 3 times the size of San Mateo Country (land mass). So I would expect SCC to have more cases, increasing at a higher rate.

Am I missing something? The per capita plots map dead on top of each other. Title should read “ Charts reveal how virus has spread at identical rates in two counties.l

Most beach communities are pleading with people not to drive to the beach if they cannot walk or ride their bike.

MidPen's large open parking lot policy fits better with this thinking:

Hate this guy's take on things? Complain to MidPen about keeping their large lots open

Aren't you tired *yet* of spamming every thread on these websites?
