Maternal mortality rates, state by state

KFF has released a new analysis outlining maternal mortality rates for every state and Washington, D.C.

KFF used 2018-22 data from the CDC's National Center for Health Statistics to compile maternal deaths and mortality rates. Maternal deaths are defined as deaths of women while pregnant or within 42 days of pregnancy termination. Only causes of death from or aggravated by pregnancy are included.  

Nationwide, 4,295 maternal deaths were reported between 2018 and 2022, resulting in a maternal mortality rate of 23.2 deaths per 100,000 live births. The U.S. has the highest maternal mortality rate of any developed nation, according to The Commonwealth Fund. 

To address this issue, CMS has proposed adding obstetrical standards for hospitals as part of its conditions of participation requirements. Hospitals and physicians have pushed back on the suggestion, arguing the approach is too punitive and could inadvertently hinder access to obstetrical care. 

Below is a breakdown of maternal mortality rates by state.

Note: KFF expressed caution at making comparisons between states, as data for many states are based on small numbers and could be statistically unreliable. The organization suppressed data for several states, if mortality rates were based on fewer than 20 deaths. Variation in state rates is likely due to differences in the quality of maternal mortality data, KFF said.
