One year of births. Many different paths.

The bigger picture
One generation.
Four different clocks.
At birth · United States, 2024
More births.
Lower fertility.
The birth count rose in 2024, while fertility reached a record low. A bigger annual count does not necessarily mean larger families.
Counts tell us how many babies arrive. Rates describe childbearing relative to the population.

Compare maternal groups
The national rate is only one view. Choose an indicator to compare reported birth outcomes and prenatal care across maternal race and Hispanic-origin groups.
First-trimester prenatal care · U.S. rate 75.5%
Each square = 0.5 percentage points. More squares means a higher rate, not a larger population. Select a group to compare all five indicators.
Square counts are rounded; labels retain the reported precision. “pp” means percentage points. Race groups are non-Hispanic and single-race. Hispanic origin includes any race. These categories describe the source data and do not explain the causes of disparities.

Data & definitions
Behind the numbers
How to read this atlas
The main source is the CDC National Center for Health Statistics’ final 2024 natality file, covering 3,628,934 registered U.S. live births.
Treemap tiles share one frame. Each tile’s area is proportional to its reported percentage; color identifies categories. The square view represents the distribution with 1,000 equal-sized marks, rounded while preserving the total. These are separate national distributions, not linked patient journeys.
The comparison grids show rates within each maternal group. Every square represents 0.5 percentage points. A group’s number of squares does not represent its population size.
Mortality uses a different scale
Maternal mortality is shown as deaths per 100,000 live births within each group. These rates do not add up to 100%, so they use a bar chart rather than a treemap.
The CDC definition includes death while pregnant or within 42 days of the end of pregnancy from a cause related to or aggravated by pregnancy or its management. It does not include every death during or after pregnancy.

Evidence across generations
Four datasets, four perspectives
These charts connect population-level findings. They do not follow the same individuals or identify the causes of fertility change, employment differences, or school enrollment change.
Total fertility rate is the number of births per woman implied by a given year’s age-specific birth rates. It is a period measure, not a prediction of an individual’s completed family size. The historical series uses final CDC data for 2010–2024.
Labor-force participation means working or actively looking for work. BLS figures describe parents with their own children under 18 living in the household. The two age groups are different groups of parents observed in 2024; the difference is not an estimate of the effect of childcare or giving birth.

California’s August 2026 enrollment series compares observed 2025–26 public enrollment with projected 2035–36 enrollment, including transitional kindergarten. The model uses births, grade progression, and county migration patterns. It does not forecast school closures. Counts shown come from the source workbook, before rounding.
The population chart uses the Census Bureau’s 2023 main projection, Table 2. The 2022 point is the base estimate; later points are projections under that series’ fertility, mortality, and migration assumptions. Connecting lines join the published years, not annual observations. The 2029 crossover comes from the Bureau’s accompanying release.
The cohort milestones show calendar ages only: children born in 2024 turn five in 2029 and 18 in 2042. School entry varies by birthday and local rules; turning 18 does not imply employment. School and population projections include many birth cohorts, migration, and mortality.
