Clark was keenly aware of the potential for bias in his data and did
his best to verify that it was representative. He comments that
wills became common fairly early, reached way down the social ladder
and that many of the will makers were illiterate, signing their wills
with an x. His conclusion is robust because you can see in the will
data a strong link between the number of *surviving* children and the
economic class determined by the assets described in the
wills. There is also a link between literacy and assets in these wills.

To a very close approximation the population was constant. If you
show that the rich as a group were more than replacing themselves,
and constrain the total population to a constant, then it's a
mathematical certainty that the poor were not replacing themselves.
If you can see a flaw in this reasoning, please point it out.
