Reminds me of Dianne's line from Bojack Horseman: "I can't believe this country hates women more than it loves guns"
In an episode where there's a huge uptick in women carrying firearms, instead of helping to make society a better place for women, they just decide to ban guns instead.
That doesn't account for population increases, but that still looks like per-capita increase nevertheless, which is embarrassing in a developed country. Especially if you compare that with other similarly developed countries with comparable populations, which mostly have a line declining to double digit totals.
EDIT: Here's data looking at the maternal mortality rate, over the same period, with a few comparable countries.
