NOTES: The general fertility rate refers to the total number of births per 1,000 women aged 15-44.

Rates for "12 months ending with quarter" (also called moving average rate) are the average rates for the 12 months that end with the quarter on the horizontal (time) axis. Estimates for the 12-month period ending with a specific quarter include all seasons of the year and, thus, are insensitive to seasonality.

A hollow circle indicates that estimates for the most recent quarter are significantly different from the same quarter of the previous year (p < 0.05); these estimates are also flagged in the data table with an asterisk (*).

Race and Hispanic origin refers to the mother.

NOTES: Age-specific birth rates refer to the total number of births per 1,000 females in each age group.

Early preterm refers to infants born at less than 34 weeks gestation, while late preterm refers to infants born at 34-36 weeks gestation. Percentages are presented to the second decimal point to better identify smaller changes and differences.
