Practical Suggestions :)

I would recommend that under causes, that culture and race be addressed indepth because there are definite differences in instances of teen pregnancy based on this. An example would be that within certain cultures abortion is frowned upon for numerous reasons that may also differ between culture. Meanwhile, abortion is much more widely accepted in other cultures/societies and would greatly impact the incidences of reported teen pregnancies and pregnancies seen through. Additionally, in different cultures it is more acceptable to become pregnant at younger ages and would also influence whether or not they would choose to proceed (and report) with the pregnancy. This could also be addressed within the effects section, because culture and religious beliefs can have an effect on the outcome of the pregnancy and how it effects the parents and child's life as well.

Geography as well as race are important factors within Canada (this is tied in with low SES). In Canada there are significantly higher rates of teen pregnancy for First Nations women and those rates vary greatly depending on their region (SES varies with region, also urban vs. rural areas having differences between pregnancy rates). Addressing the experience for First Nations women during pregnancy would also be a valuable topic to cover generally as their experience often is often quite a bit different than that of other women.

Here is an article that covers some of this from the perspective of women in Manitoba: http://ir.lib.uwo.ca/cgi/viewcontent.cgi?article=1117&context=iipj

Here is some statistical information in regards to pregnancy and First Nations women from the government of Canada: http://www.hc-sc.gc.ca/fniah-spnia/pubs/aborig-autoch/2009-stats-profil-vol2/index-eng.php

Here is a figure of First Nation birthrates in comparison to other Canadians by age group: http://www.hc-sc.gc.ca/fniah-spnia/pubs/aborig-autoch/stats-profil-atlant/index-eng.php#fig5

A final note that I would like to make is under effects of teenage pregnancy to include fathers as main category like "Mothers" and "Child". Although many times fathers are not involved, there are many who are and it definitely does effect them too!

This is a really interesting topic and you covered a lot of material!
