As confirmed by official data shared, for the second consecutive year, a rise in the birth rate among teens had been recorded for 2007, fueling concerns that all efforts to curb teen pregnancies are not giving out the results that they once did.

Between 2005 and 2007, the rate of teen births hiked by 5%, which had come after a 34% drop that, was recorded from 1991 to 2005.

2007 was the last year for which the figures were available, and revealed that the birth rate among teens surged by nearly 1%, with "42.5 babies born for every 1,000 teens aged 15 to 19". Also, the overall birth rate hiked by 1% as well between 2006 and 2007, with a record number of 4.3 million babies born across the US.

"The average woman is still having two children. hat hasn’t really changed much in recent years", said CDC chief of reproductive statistics Stephanie J. Ventura, while stressing that the record number of births is a direct result of the "growing population", and definitely "not indicative of a new baby boom".

The team which conducted the analysis was led by researcher John Santelli, MD, MPH, who chairs Columbia University’s Clinical Population and Family Health department, and details of the research have been published in the online edition of the journal Pediatrics.
