The Problem

Most U.S. maternal deaths are preventable.

The United States has the highest maternal mortality rate of any wealthy nation — and unlike its peers, that rate is getting worse. This project investigates why, where intervention would matter most, and what policy exports from top-performing countries could look like in practice.

58.6

the highest regional MMR — Southeast Arkansas. More than 3× the rate of the safest region in the same three states.

17.8

the lowest — Northern Mississippi. Still nearly 10× the rate in Norway, the world's safest country to give birth.

If the U.S. matched Norway's maternal mortality rate, roughly 9 out of every 10 American mothers who die each year would live. Back-of-envelope · OECD 2020 · CDC 2023
01 · Purpose

Why this project exists.

Maternal mortality is one of the only headline health indicators where the U.S. has gone backwards while every comparable country has improved. Our goal is to make the scale of that reversal unignorable — and to trace it to specific, fixable causes.

We're building a data-first investigation that (a) examines regional and racial disparities in maternal death, (b) identifies the leading causes and how they've shifted, (c) benchmarks U.S. performance against top-performing countries to surface transferable policy, and (d) investigates why U.S. rates continue to rise while peer countries' fall.

02 · Assumptions

What we're taking as given.

The data sources we rely on — CDC NCHS, the World Bank, OECD, and peer-reviewed work out of NEJM and NIH — each involve methodology choices. These are the priors we're operating under:

Definition

We use the WHO definition of a maternal death: a death during pregnancy or within 42 days of its end from pregnancy-related causes.

Preventability

We accept the CDC's Maternal Mortality Review Committees' standard that a death is "preventable" if reasonable changes by patient, provider, facility, system, or community could have averted it.

Comparability

Cross-country comparisons use OECD harmonized rates. U.S. state and county-level numbers may be noisier and we flag small-n rows.

Scope

We focus on deaths within the 42-day window. Extending to 1 year (late maternal deaths) roughly doubles the U.S. figure, but that's for a later build.

Findings

The data.

Three tables pulled directly from our database, each paired with three visualizations. Every number on this page comes from one of our three PHP endpoints — the same feeds that will power live, interactive versions in M3.

Disparity scrubber

A slider across the 14 regions that re-sorts the chart in real time — by MMR, by birth center count, or by the ratio between the two. A second toggle lets the user isolate one state at a time for apples-to-apples comparison. The goal: turn this static ranking into a hands-on comparison tool.

Access-desert spotter

A filterable county explorer: set a minimum population and a maximum birth-centers threshold, and the map + table update to show only qualifying access deserts. Hover reveals drive-time to the nearest center in a neighboring county. This turns a static 230-row dataset into a targeting tool for policy advocacy.

Counterfactual calculator

If a user picks any access-desert county, the tool models what its MMR would look like if it matched the access ratio of the best-performing county in the same region. Converts a statistical relationship into a concrete number: "In my county, X preventable deaths per year."
