It's true, there is a slightly higher risk of death for women who have children later, but nothing like the risk from 100 years ago or more. Thanks science! (oh right, science is fake, damn. Forgot about that.)
All in all it might be a worthy trade-off for many women.
Again, Texas is an outlier here. Their rates doubled in the space of 4 years (actually 1 year essentially), which coincided with the closure of a lot of women's health care clinics. Clearly something else is going on there besides older women having children.
Here is the long term trend through the late 1990s:
At the beginning of the 20th century, for every 1000 live births, six to nine women in the United States died of pregnancy-related complications, and approximately 100 infants died before age 1 year (1,2). From 1915 through 1997, the infant mortality rate declined greater than 90% to 7.2 per 1000 live births, and from 1900 through 1997, the maternal mortality rate declined almost 99% to less than 0.1 reported death per 1000 live births (7.7 deaths per 100,000 live births in 1997) (3) (Figure 1 and Figure 2).
