# Proving or disproving hypothesis?

I took statistics class years ago in my college and I don't remember much of it now. I am into public policy research now and I am bit confused about about what conclusion to make from available evidence.

Poverty is the 'root cause' of child labour is what is claimed by International Labour organization (ILO) and thus by lot of other countries. Evidence often cited for this is: most of the child labourers are from poor backgrounds in most of the countries where child labour is prevalent. So there is a correlation and for causality, if we think about it, no money => to earn money => all healthy individuals must work including children => child labourers.

Now I've read few research studies which claim that Poverty is not the root cause of child labour and the evidence they cite is,

1. There are poor countries where there is hardly any child labourers.
2. There are children studying in schools who are lot more impoverished than those who are working.
3. There doesn't exist a poverty line below which a parent is compelled to send their child to school.

So people on this end say, if poverty is the root cause then could we explain this. But this argument could be reversed too. Either way, I'm confused.

How should I go about interpreting and understanding this?

What data is required, and what analysis has to be carried out to settle the question, whether poverty is the cause or not? In other words, I want to set my hypothesis to be "Poverty is not the root cause of child labour", what should I do to either prove or disprove it?

I want to see this to the end. So feel free suggest some readings if you need to.

• If you assume that the parents are rational then they weigh in the benefit of getting some money from a child now vis-a-vis this child's expected earning potential in future. In the economy where education doesn't impact expected earnings in future, it's rational to make a child work now rather than sending it to school. – Aksakal Oct 8 '15 at 13:10
• Can you clarify the statistical content here? At present this seems like it belongs on Economics or a sociology SE site, if there is one. – gung Oct 8 '15 at 14:13
• @gung: Honestly, I too was in confusion regarding where to ask this question. Kindly migrate it to which ever the site where this is appropriate. – claws Oct 8 '15 at 16:37
• There isn't a sociology SE, as far as I can tell. You could look at econ.SE & decide if you like the idea of going there. If so, flag your Q for the moderators to migrate it. – gung Oct 8 '15 at 16:39

• but making a statistical case for causality would require digging much further into the data. This is also why I asked question in this forum. If it is not too much to ask, can you tell me, what data is required, and what analysis has to be carried out to settle the question, whether poverty is the cause or not? In other words, I want to set my hypothesis to be "Poverty is not the root cause of child labour", what should I do to either prove or disprove it? – claws Oct 8 '15 at 13:34
• ... precludes the possibility that child labour is a necessary condition of poverty. Did you intend to write ... precludes the possibility that poverty is a necessary condition of child labour. – claws Oct 8 '15 at 13:39
