Saloni Dattani, a researcher at Our World in Data, joins Tim Harford to uncover how a simple tick box on death certificates led to a doubling of US maternal mortality rates. The podcast explores the impact of changes in data collection methods, discrepancies in maternal mortality data due to checkbox usage, and the implications of counting all deaths with the checkbox ticked as maternal deaths.
Misleading rise in US maternal mortality rates due to flawed data collection methods.
Implementation of a pregnancy checkbox system led to significant inaccuracies in reported maternal deaths.

Understanding the Rise in US Maternal Mortality Rates
The podcast delves into the increase in maternal mortality rates in the US since the early 2000s, a stark contrast to the global decline. The World Health Organization's broad definition of maternal deaths led to a discrepancy in counting these deaths. The US introduced a pregnancy checkbox system that significantly increased reported maternal deaths, regardless of the actual cause being pregnancy-related. This method created a misleading rise in maternal mortality rates, making accurate data interpretation challenging.
Challenges with US Maternal Mortality Data Collection
The US implemented the pregnancy checkbox gradually across states over 15 years, resulting in a gradual rise in reported maternal mortality rates. Research revealed that the checkbox system led to false positives, with cases of older women marked as pregnant, highlighting inaccuracies in the data collection method. The introduction of more quality checks and revised rules aimed to address these data collection challenges, but the overall US maternal mortality data from 2003 to 2018 remains unreliable and complicates international comparisons.
he US has been portrayed as in the grip of a maternal mortality crisis. In contrast to most other developed nations, the rate of maternal deaths in the US has been going up since the early 2000s.
But why? With the help of Saloni Dattani, a researcher at Our World in Data, Tim Harford explores how a gradual change in the way the data was gathered lies at the heart of the problem.
