The whole argument is null without some hard facts behind it. we need economic data, social data. This really is very very poor research, if indeed this is what it it.
anecdotal therefore:
the teenage part of the question hasn't been discussed and i would like to address it.
IMO and Experience ( life and working with socially isolated/disadvantaged people) there are three factors
education - not just sex ed - but education in general
hope
culture
To be frank, the Conservatives are butchering the support mechanisms which allow severely disadvantaged children to access basic education in schools - because this requires support to the parents - and the Conservatives consider them feckless and workshy.
without support for the existing parents, some children don't get even a basic education
Schools are spending their time sorting out problems, support mechanisms and the like for families instead of educating children
and this is becuase our education system is like a funnel where you, or jamie oliver or anyone who wants to do anything with or to our children, can do it through this system
you are not letting children learn - the ones that get there. You are not letting teachers teach. they are becoming some kind of school/socialworkery/media bandwagony/multiagency place.
some wanker in whitehall probably showed another wanker in higher political office a chart and said the word 'streamlining' 'funneling' 'interagency co-operation' rubbish.
i digress
so those children from the most vulnerable families the most socially and economically disadvantaged........do not get hope and they don't get to dream.
These kids aren't stupid, at 13 they know already - that childhood imaginings of a fireman or some such is unreachable. they disconnect - why bother when your future for the next 55 years is minimum wage at the new asda down the road.
the kids who do dream, go to college, uni etc - if you actually did your own real research and got some graphs, i would wager that those with low educational achievement ergo - no hopes, no dreams were the most likley candidates to be pregnant or get someone pregnant as a teenager. now, not all of course .
at 16 you get out of that shithole you call a home ( the one the Labout and Conservative governments shat all over and didn't give enough support via services and intervention) someone loves you and you can have your own family.
There is a lot of naivity involved too - some schools do the crying doll thing
but then they cost money - so actually some do a fucking bag of flour.
why bother? really? a bag of flour.
there needs to be a change in prevailing societal culture.
All parents need parenting classes - we aren't given an instruction leaflet you know,
its not like a washing machine. and your target audience probably isn't going to read the mumsnet guide to rearing a boden baby fnar fnar. or similar.
jamie oliver ( god bless his little scooter) DID absolutely change britains ddietary habits
supermarkets got in on the thing, kids were saying " no mum i am not allowed a penguin bar in my lunch box" etc
and in societal terms, that happened so very very very very quickly.
You can - if you wanted to ( which Conservative govts dont really want to) change the societal culture.
by introducing some from pf parent support and education group (class) where dads and mums learn before birth about breastfeeding, great nutrition, how to handle a colicky baby, what to do when you thing you want to throw your baby out of the window, how to talk to your baby, how to set boundries for your toddler. that smacking isn't the best way, that smoking in front of children in your house is so 10 years ago. That as a parent, your job is to keep your child safe, not be a threat to them - that you sare allowed to have hope for yourself - still - that there are educational opportunities available to you still ....my god the list is endless.
and this should be on condition of receiving child benefit. thsi then could be your new social interagency wanky bolockses 'HUB' for professionals to work through and let the schools teach the kids.
