To disentangle things, we look at the original relationship between wealth
and residence, controlling for family size. Table 21.9 shows that when we do
that, the effect of residence on economic status remains insignificant for rural
people, but it makes a big difference for urban residents. When we look at
the relationship between wealth and education in table 21.10, we see that the
influence of education on wealth is insignificant for large families, but is
highly significant for small families.
To get the full picture, we now produce table 21.11, which shows the bivariate
relationship between wealth status and education, now controlling for both
family size and residence simultaneously.
