Quarterly Provisional Estimates for Selected Birth Indicators, 2022-Quarter 2, 2024

View interactive dashboard of quarterly provisional estimates of natality.

Provisional estimates are based on a snapshot of all vital statistics birth certificate data received and processed by the National Center for Health Statistics (NCHS) as of a specified cutoff date. Provisional estimates closely match final data, but they are subject to revision in future quarterly releases as additional records for that quarter are received. See Technical Notes for more details.

In this release of Quarterly Provisional Estimates, NCHS presents estimates of selected reproductive indicators from birth data for 2022 through the second quarter of 2024. Estimates for 2022 and 2023 are based on final data (1); estimates for 2024 are based on provisional data. The estimates are based on all birth records received and processed by NCHS as of July 31, 2024. Estimates are presented for: general fertility rates, age-specific birth rates, total and low-risk cesarean delivery and vaginal birth after cesarean rates, preterm and other gestational age birth rates, low birthweight, neonatal intensive care unit admission and Medicaid as a source of payment for the delivery. These indicators were selected based on their importance for public health surveillance as well as the feasibility of producing reliable estimates using available provisional data (2). Future quarterly releases may include additional birth indicators from natality data. The rates and percentages for a 12-month moving average are presented to account for seasonality. Estimates for the 12-month period ending with the fourth quarter in each year can be interpreted as an annual provisional estimate for that year. Differences are reported only if statistically significant (p<0.05).
