Births and delivery volume

Births are the denominator for everything else in this market. This layer uses the Census Bureau's Vintage 2024 county population estimates, which publish births as a component of population change for every county with no suppression — a county-complete series, which the more commonly cited natality extracts are not.

The county map

Births by U.S. county, 2024 A county choropleth of births recorded in 2024 for every U.S. county.
Births, 2024 ≤ 50 > 5,000 withheld / not published (0)

Counties are drawn from Census cartographic boundary files (2023, 1:20,000,000) and projected to an Albers equal-area conic at build time. This map contains no JavaScript mapping library, loads no external resource, and makes no network request. Hatched counties are withheld at source — they are not zero and they are not estimated.

Figure 1. Every county is present and coloured; there is nothing hatched on this map, because this source suppresses nothing. That is unusual and it is the reason we chose it.

Figure 2 — four years, six series. Direction differs by state, and the national figure hides it. Every value is a published Census estimate; none is interpolated. A market sized on the national trend will be wrong in most individual states. Size your own.

Where the volume is

Twenty highest-volume counties, 2024. With legal and delivery capacity alongside, because volume alone is not opportunity.

Ten largest counties by births. Births in 2024 for the ten highest-volume U.S. counties. Los Angeles, CA 93,953 Harris, TX 65,668 Cook, IL 51,412 Maricopa, AZ 50,770 Dallas, TX 36,983 San Diego, CA 35,738 Kings, NY 31,350 Orange, CA 30,291 Miami-Dade, FL 29,253 Tarrant, TX 28,013
Figure 3 — volume is extremely concentrated. The ten largest counties account for a substantial share of national births. That concentration is why national benchmarks are close to useless for a single-market firm, and why we build geographic bid modifiers from this layer rather than from platform defaults.

What this measure is, exactly

Definition and limits. Read before quoting any figure on this page.
QuestionAnswer
What is counted?Births occurring during the estimate year to residents of the county, as recorded in the Census Bureau’s components-of-change series.
Residence or occurrence?Residence. A birth at a hospital in the next county is counted in the mother’s county of residence. This matters when reading the delivery-capacity layer alongside it.
Is it suppressed anywhere?No. That is why this source was chosen over county-level natality extracts, which restrict county identification below a population threshold.
Is it an estimate?Yes — it sits inside the population estimates programme and is revised with each vintage. It is not the final natality file. We state the vintage on every figure.
Does it say anything about birth injury?No. It is a denominator. It carries no information about outcomes, adverse events, or claims, and we never present it as though it does.

A limit we will not cross. Nothing on this page links a clinical outcome rate to a legal claim. Adverse-event rates measure medicine. Litigation measures a legal process. They are different quantities, they are collected by different agencies for different reasons, and correlating them would be the fastest way to publish something false. Where we present clinical data and legal data together, it is to describe a market — never to imply that one causes, predicts, or justifies the other.
