How to use the map:
- Hover over different circles to see the zip code, the number of deliveries in our data between 2010-2015, and the C-section rate for that area.
- The size of the circle represents the number of deliveries—the bigger the circle, the more babies delivered in that area.
- The color of the circle represents the C-section rate—orange indicates a higher-than-average C-section rate, blue indicates a lower-than-average C-section rate.
- In the upper right-hand corner, look for the “Choose a group” menu to switch from looking at data for all deliveries to just the data for women who had a previous C-section.
