2010年至2011年间，美国的出生人数下降了1%，总数为3953 593人。一般生育率也下降了1%，降至每1000名妇女生育63.2个孩子，这是有报告以来的最低比率。2011年，总生育率下降了2%（每1000名妇女生育1894.5个孩子）。2011年，青少年生育率降至历史最低点，每1000名妇女生育31.3个孩子。20岁至29岁女性的出生率也有所下降，但35岁至39岁和40岁至44岁女性的出生率有所上升。未婚女性生育的比例从2010年的40.8%略微下降到2011年的40.7%。2011年剖宫产率与2010年持平，为32.8%。2011年早产率连续5年下降，为11.72%；低出生体重率略有下降，为8.10%。2011年，婴儿死亡率为每千名活产婴儿死亡6.05人，与2010年6.15人的死亡率相比没有显著下降。2011年出生时的预期寿命为78.7岁，与2010年持平。2010年至2011年期间，1至19岁儿童的粗死亡率没有显著变化。在这一年龄组中，意外伤害和凶杀分别是第一和第二大死因。2011年，这两种死因合计占儿童和青少年死亡总数的47.0%。儿科2013;131:548 - 558
The number of births in the United States declined by 1% between 2010 and 2011, to a total of 3 953 593. The general fertility rate also declined by 1% to 63.2 births per 1000 women, the lowest rate ever reported. The total fertility rate was down by 2% in 2011 (to 1894.5 births per 1000 women). The teenage birth rate fell to another historic low in 2011, 31.3 births per 1000 women. Birth rates also declined for women aged 20 to 29 years, but the rates increased for women aged 35 to 39 and 40 to 44 years. The percentage of all births to unmarried women declined slightly to 40.7% in 2011, from 40.8% in 2010. In 2011, the cesarean delivery rate was unchanged from 2010 at 32.8%. The preterm birth rate declined for the fifth straight year in 2011 to 11.72%; the low birth weight rate declined slightly to 8.10%. The infant mortality rate was 6.05 infant deaths per 1000 live births in 2011, which was not significantly lower than the rate of 6.15 deaths in 2010. Life expectancy at birth was 78.7 years in 2011, which was unchanged from 2010. Crude death rates for children aged 1 to 19 years did not change significantly between 2010 and 2011. Unintentional injuries and homicide were the first and second leading causes of death, respectively, in this age group. These 2 causes of death jointly accounted for 47.0% of all deaths of children and adolescents in 2011. Pediatrics 2013;131:548-558
