NCHS birth tables with a variety of variables for selection are available at http://www.cdc.gov/nchs/datawh/vitalstats/VitalStatsbirths.htm.
By selecting the national or subnational (i.e., state and some county) levels, you can find specific statistics for national, state, and some county birth rates, fertility rates, method of delivery (vaginal or cesarean), length of pregnancy, birthweight, characteristics of the mother (i.e., age, race, marital status, education), prenatal care, and risk factors (i.e., diabetes, hypertension, and smoking). For journalists who need assistance, feel free to contact the NCHS press office.
