Larch,
I'm afraid I must disagree with this assertion. Yes, they do come from less privileged backgrounds. This emphatically does not mean they have LESS access to good sex education, nor does it mean they have less access to contraception. In the extremely poor urban community I work, with a large immigrant and non-white, low SES population, the city and county have spent extravagant sums on sex education in middle and high school (6-12), contraception is readily available at county and city health clinics, the STD clinics and the numerous public health clinics in the city. These clinics are all on public bus routes, and are geographically dispersed. I personally work in one on Saturday mornings. In addition the several Planned Parenthood offices, to their credit do distribute birth control, but they charge for it. The public clinics do not.
I agree that the issue is significantly higher in the low SES, but do not have the statistics to support this belief at hand. What is puzzling, is why this seems to be so? This is an issue not limited to birth control/abortions, but all areas of health in general. I have seen more bulky cervical cancer on initial exams in this group than I do in the suburban clinic, too. Paps are available in both communities, they cost the indigent far less than the suburbanites pay (free), yet women ignore something as basic as an annual.
Both issues are huge public health concerns, the cost for the low SES population in my community is borne by the county and state, (and probably the feds - which means you and I), yet, it remains a serious issue.
Certainly, Isle Five, is any number of impoverished communities in the US and I'm sure, elsewhere. With a full court press of education, free availability of contraception, we still have the problem, and abortions are still performed, and, if we consider abortion contraception, it is costly to the impoverished and wealthy alike, since the government is prohibited from paying for it, which is why electives are done off campus.
