Britain’s National Health Service turns 75 years-old this week. But as reporter Suzi Ring and editor Andre Tartar explain in the latest episode of In the City, rather than being a cause for celebration, the NHS anniversary comes at a critical, maybe even dire moment for the service.

Ring and Tartar unpack Bloomberg’s first-of-its-kind analysis of NHS data for eight indicators—including ambulance waiting times, cancer treatment times, overnight hospital bed availability and wait times for diagnostic tests. The study underscores how deep the problems run at the publicly-funded health service—and how difficult they may be to fix.
