Edit: as pointed out below, these numbers are for type 1 and 2, so the population is requiring insulin is much lower than this.

Among the U.S. population overall, crude estimates for 2021 were:

• 38.4 million people of all ages—or 11.6% of the U.S. population—had diabetes.

• 38.1 million adults aged 18 years or older—or 14.7% of all U.S. adults—had diabetes (Table 1a; Table 1b).

Sure, the majority of folks don’t have diabetes, but come on, this affects a huge number of people, and I would bet that a vast, vast majority of people at least know someone with diabetes.

And yes, those are national whereas this is California—but it’s also about changing hearts and minds. When someone from Texas, struggling to pay for their kid’s insulin, learns about this, they might just question some things.
