This report presents several key demographic and maternal and infant health indicators using 2016 final birth data. Trends in the general fertility rate (the number of births per 1,000 women aged 15–44), age-specific birth rates, cesarean delivery, preterm, and triplet and higher-order multiple birth rates are presented by age of mother. For each indicator, data for 2016 are compared with 2015, and also with a year representing a recent high or low rate.
