>Here are some CDC data: http://www.cdc.gov/Features/dsTeenPregnancy/ Current US teen pregnancy rate is 39.1% compared to 72.2% in the 2005 data. Current rates are the lowest since recording began in the 1940s. US Black and Hispanic rates still are an order of magnitude higher than US whites whose rates now are only slightly higher than those for the UK.

As Alan points out there is nothing in that link attempting a correlation between pregnancy rates and type of sex education provided - the link I posted, while old, at least provides that. And although the link says 'TeenPregnancy' the figures relate to teen birth rates which, to my mind, is not the same thing at all - it would be interesting to see how international comparisons look using the former measurement.....
