In 2010 there were 34.3 births among every thousand girls between the ages of 15 and 19. That’s down 9 percent from 2009. And it’s the lowest number in nearly seven decades of reporting.
2010年每一千個15歲到19歲的少女里，就有34.3個做媽了。這個數(shù)據(jù)比2009年低了9個百分點。同時，也是近70年來的最低值。

The figure comes from a new report from the Centers for Disease Control and Prevention called Births: Preliminary Data for 2010. [Brady E. Hamilton, Joyce A. Martin and Stephanie J. Ventura] And it’s filled with interesting stats. For one, teen births have hit that record low. And that statistic includes more good news – birth rates are at record lows for all ethnic and racial groups, and even for younger teenagers.
這個數(shù)據(jù)來自于疾病預防控制中心的一份新的報告，報告名為“出生：2010的初步數(shù)據(jù)”。這份報告中充滿了有趣的數(shù)據(jù)。比如，青少年分娩創(chuàng)歷史新低。當然，也有好消息：各種族的出生率都創(chuàng)歷史新低，即使是對青少年群體來講也是一樣的。

The number of births to unmarried moms also declined. And pre-term births declined. The trend towards lower numbers is general - the birth rate fell overall by 3 percent. It’s also down for women in their twenties and thirties.
未婚媽媽的數(shù)量也減少了。而且早產率也下降了。各項數(shù)據(jù)下降是主流，出生率總體下降了3%。20到30歲的婦女的分娩率也下降了。?

The one place where there was a rise? Births to women in their early forties. That figure rose slightly, from 10 births per thousand women to 10.2. Which is the highest rate since 1967. The data include nearly every recorded birth in all 50 states, DC, and the U.S. territories. To access the report, just go to
難道就沒有個增長的數(shù)據(jù)了嗎？40歲出頭的女性的分娩率從1%上升到1.02%，同時這也創(chuàng)了1967年來的新高。在每一塊美國國土上，幾乎每一個有記錄的出生情況都是這份報告的數(shù)據(jù)來源。
